RFC3306 - Unicast-Prefix-based IPv6 Multicast Addresses
RFC3314 - Recommendations for IPv6 in Third Generation Partnership Project (3GPP) Standards
RFC3316 - Internet Protocol Version 6 (IPv6) for Some Second and Third Generation Cellular Hosts
RFC3484 - Default Address Selection for Internet Protocol version 6 (IPv6): This document describes two algorithms, for source address selection and for destination address selection. The algorithms specify default behavior for all Internet Protocol version 6 (IPv6) implementations. They do not override choices made by applications or upper-layer protocols, nor do they preclude the development of more advanced mechanisms for address selection. The two algorithms share a common context, including an optional mechanism for allowing administrators to provide policy that can override the default behavior. In dual stack implementations, the destination address selection algorithm can consider both IPv4 and IPv6 addresses - depending on the available source addresses, the algorithm might prefer IPv6 addresses over IPv4 addresses, or vice-versa. All IPv6 nodes, including both hosts and routers, must implement default address selection as defined in this specification. [STANDARDS-TRACK]
RFC3493 - Basic Socket Interface Extensions for IPv6: The de facto standard Application Program Interface (API) for TCP/IP applications is the "sockets" interface. Although this API was developed for Unix in the early 1980s it has also been implemented on a wide variety of non-Unix systems. TCP/IP applications written using the sockets API have in the past enjoyed a high degree of portability and we would like the same portability with IPv6 applications. But changes are required to the sockets API to support IPv6 and this memo describes these changes. These include a new socket address structure to carry IPv6 addresses, new address conversion functions, and some new socket options. These extensions are designed to provide access to the basic IPv6 features required by TCP and UDP applications, including multicasting, while introducing a minimum of change into the system and providing complete compatibility for existing IPv4 applications. Additional extensions for advanced IPv6 features (raw sockets and access to the IPv6 extension headers) are defined in another document. This memo provides information for the Internet community.
RFC3513 - Internet Protocol Version 6 (IPv6) Addressing Architecture: This specification defines the addressing architecture of the IP Version 6 (IPv6) protocol. The document includes the IPv6 addressing model, text representations of IPv6 addresses, definition of IPv6 unicast addresses, anycast addresses, and multicast addresses, and an IPv6 node's required addresses. [STANDARDS-TRACK]
RFC3531 - A Flexible Method for Managing the Assignment of Bits of an IPv6 Address Block: This document proposes a method to manage the assignment of bits of an IPv6 address block or range. When an organisation needs to make an address plan for its subnets or when an ISP needs to make an address plan for its customers, this method enables the organisation to postpone the final decision on the number of bits to partition in the address space they have. It does it by keeping the bits around the borders of the partition to be free as long as possible. This scheme is applicable to any bits addressing scheme using bits with partitions in the space, but its first intended use is for IPv6. It is a generalization of RFC 1219 and can be used for IPv6 assignments. This memo provides information for the Internet community.
RFC3542 - Advanced Sockets Application Program Interface (API) for IPv6: This document provides sockets Application Program Interface (API) to support "advanced" IPv6 applications, as a supplement to a separate specification, RFC 3493. The expected applications include Ping, Traceroute, routing daemons and the like, which typically use raw sockets to access IPv6 or ICMPv6 header fields. This document proposes some portable interfaces for applications that use raw sockets under IPv6. There are other features of IPv6 that some applications will need to access: interface identification (specifying the outgoing interface and determining the incoming interface), IPv6 extension headers, and path Maximum Transmission Unit (MTU) information. This document provides API access to these features too. Additionally, some extended interfaces to libraries for the "r" commands are defined. The extension will provide better backward compatibility to existing implementations that are not IPv6-capable. This memo provides information for the Internet community.
RFC3587 - IPv6 Global Unicast Address Format: This document obsoletes RFC 2374, "An IPv6 Aggregatable Global Unicast Address Format". It defined an IPv6 address allocation structure that includes Top Level Aggregator (TLA) and Next Level Aggregator (NLA). This document makes RFC 2374 and the TLA/NLA structure historic. This memo provides information for the Internet community.
RFC3697 - IPv6 Flow Label Specification: This document specifies the IPv6 Flow Label field and the minimum requirements for IPv6 source nodes labeling flows, IPv6 nodes forwarding labeled packets, and flow state establishment methods. Even when mentioned as examples of possible uses of the flow labeling, more detailed requirements for specific use cases are out of scope for this document. The usage of the Flow Label field enables efficient IPv6 flow classification based only on IPv6 main header fields in fixed positions. [STANDARDS-TRACK]
RFC3769 - Requirements for IPv6 Prefix Delegation: This document describes requirements for how IPv6 address prefixes should be delegated to an IPv6 subscriber's network (or "site"). This memo provides information for the Internet community.
RFC3879 - Deprecating Site Local Addresses: This document describes the issues surrounding the use of IPv6 site-local unicast addresses in their original form, and formally deprecates them. This deprecation does not prevent their continued use until a replacement has been standardized and implemented. [STANDARDS-TRACK]
RFC4007 - IPv6 Scoped Address Architecture: This document specifies the architectural characteristics, expected behavior, textual representation, and usage of IPv6 addresses of different scopes. According to a decision in the IPv6 working group, this document intentionally avoids the syntax and usage of unicast site-local addresses. [STANDARDS-TRACK]
RFC4022 - Management Information Base for the Transmission Control Protocol (TCP): This memo defines a portion of the Management Information Base (MIB) for use with network management protocols in the Internet community. In particular, it describes managed objects used for implementations of the Transmission Control Protocol (TCP) in an IP version independent manner. This memo obsoletes RFCs 2452 and 2012. [STANDARDS-TRACK]
RFC4087 - IP Tunnel MIB: This memo defines a Management Information Base (MIB) module for use with network management protocols in the Internet community. In particular, it describes managed objects used for managing tunnels of any type over IPv4 and IPv6 networks. Extension MIB modules may be designed for managing protocol-specific objects. Likewise, extension MIB modules may be designed for managing security-specific objects. This MIB module does not support tunnels over non-IP networks. Management of such tunnels may be supported by other MIB modules. This memo obsoletes RFC 2667. [STANDARDS-TRACK]
RFC4113 - Management Information Base for the User Datagram Protocol (UDP): This memo defines a portion of the Management Information Base (MIB) for use with network management protocols in the Internet community. In particular, it describes managed objects used for implementations of the User Datagram Protocol (UDP) in an IP version independent manner. This memo obsoletes RFCs 2013 and 2454. [STANDARDS-TRACK]
RFC4191 - Default Router Preferences and More-Specific Routes: This document describes an optional extension to Router Advertisement messages for communicating default router preferences and more-specific routes from routers to hosts. This improves the ability of hosts to pick an appropriate router, especially when the host is multi-homed and the routers are on different links. The preference values and specific routes advertised to hosts require administrative configuration; they are not automatically derived from routing tables. [STANDARDS-TRACK]
RFC4193 - Unique Local IPv6 Unicast Addresses: This document defines an IPv6 unicast address format that is globally unique and is intended for local communications, usually inside of a site. These addresses are not expected to be routable on the global Internet. [STANDARDS-TRACK]
RFC4291 - IP Version 6 Addressing Architecture: This specification defines the addressing architecture of the IP Version 6 (IPv6) protocol. The document includes the IPv6 addressing model, text representations of IPv6 addresses, definition of IPv6 unicast addresses, anycast addresses, and multicast addresses, and an IPv6 node's required addresses.; This document obsoletes RFC 3513, "IP Version 6 Addressing Architecture". [STANDARDS-TRACK]
RFC4292 - IP Forwarding Table MIB: This document defines a portion of the Management Information Base (MIB) for use with network management protocols in the Internet community. In particular, it describes managed objects related to the forwarding of Internet Protocol (IP) packets in an IP version-independent manner. This document obsoletes RFC 2096. [STANDARDS-TRACK]
RFC4293 - Management Information Base for the Internet Protocol (IP): This memo defines a portion of the Management Information Base (MIB) for use with network management protocols in the Internet community. In particular, it describes managed objects used for implementations of the Internet Protocol (IP) in an IP version independent manner. This memo obsoletes RFCs 2011, 2465, and 2466. [STANDARDS-TRACK]
RFC4294 - IPv6 Node Requirements: This document defines requirements for IPv6 nodes. It is expected that IPv6 will be deployed in a wide range of devices and situations. Specifying the requirements for IPv6 nodes allows IPv6 to function well and interoperate in a large number of situations and deployments. This memo provides information for the Internet community.
RFC4311 - IPv6 Host-to-Router Load Sharing: The original IPv6 conceptual sending algorithm does not do load sharing among equivalent IPv6 routers, and suggests schemes that can be problematic in practice. This document updates the conceptual sending algorithm in RFC 2461 so that traffic to different destinations can be distributed among routers in an efficient fashion. [STANDARDS-TRACK]
RFC4389 - Neighbor Discovery Proxies (ND Proxy): Bridging multiple links into a single entity has several operational advantages. A single subnet prefix is sufficient to support multiple physical links. There is no need to allocate subnet numbers to the different networks, simplifying management. Bridging some types of media requires network-layer support, however. This document describes these cases and specifies the IP-layer support that enables bridging under these circumstances. This memo defines an Experimental Protocol for the Internet community.
RFC4429 - Optimistic Duplicate Address Detection (DAD) for IPv6: Optimistic Duplicate Address Detection is an interoperable modification of the existing IPv6 Neighbor Discovery (RFC 2461) and Stateless Address Autoconfiguration (RFC 2462) processes. The intention is to minimize address configuration delays in the successful case, to reduce disruption as far as possible in the failure case, and to remain interoperable with unmodified hosts and routers. [STANDARDS-TRACK]
RFC4443 - Internet Control Message Protocol (ICMPv6) for the Internet Protocol Version 6 (IPv6) Specification: This document describes the format of a set of control messages used in ICMPv6 (Internet Control Message Protocol). ICMPv6 is the Internet Control Message Protocol for Internet Protocol version 6 (IPv6). [STANDARDS-TRACK]
RFC4489 - A Method for Generating Link-Scoped IPv6 Multicast Addresses: This document specifies an extension to the multicast addressing architecture of the IPv6 protocol. The extension allows the use of Interface Identifiers (IIDs) to allocate multicast addresses. When a link-local unicast address is configured at each interface of a node, an IID is uniquely determined. After that, each node can generate its unique multicast addresses automatically without conflicts. The alternative method for creating link-local multicast addresses proposed in this document is better than known methods like unicast-prefix-based IPv6 multicast addresses. This memo updates RFC 3306. [STANDARDS-TRACK]
RFC4620 - IPv6 Node Information Queries: This document describes a protocol for asking an IPv6 node to supply certain network information, such as its hostname or fully-qualified domain name. IPv6 implementation experience has shown that direct queries for a hostname are useful, and a direct query mechanism for other information has been found useful in serverless environments and for debugging. This memo defines an Experimental Protocol for the Internet community.
RFC4861 - Neighbor Discovery for IP version 6 (IPv6): This document specifies the Neighbor Discovery protocol for IP Version 6. IPv6 nodes on the same link use Neighbor Discovery to discover each other's presence, to determine each other's link-layer addresses, to find routers, and to maintain reachability information about the paths to active neighbors. [STANDARDS-TRACK]
RFC4862 - IPv6 Stateless Address Autoconfiguration: This document specifies the steps a host takes in deciding how to autoconfigure its interfaces in IP version 6. The autoconfiguration process includes generating a link-local address, generating global addresses via stateless address autoconfiguration, and the Duplicate Address Detection procedure to verify the uniqueness of the addresses on a link. [STANDARDS-TRACK]
RFC4941 - Privacy Extensions for Stateless Address Autoconfiguration in IPv6: Nodes use IPv6 stateless address autoconfiguration to generate addresses using a combination of locally available information and information advertised by routers. Addresses are formed by combining network prefixes with an interface identifier. On an interface that contains an embedded IEEE Identifier, the interface identifier is typically derived from it. On other interface types, the interface identifier is generated through other means, for example, via random number generation. This document describes an extension to IPv6 stateless address autoconfiguration for interfaces whose interface identifier is derived from an IEEE identifier. Use of the extension causes nodes to generate global scope addresses from interface identifiers that change over time, even in cases where the interface contains an embedded IEEE identifier. Changing the interface identifier (and the global scope addresses generated from it) over time makes it more difficult for eavesdroppers and other information collectors to identify when different addresses used in different transactions actually correspond to the same node. [STANDARDS-TRACK]
RFC5072 - IP Version 6 over PPP: The Point-to-Point Protocol (PPP) provides a standard method of encapsulating network-layer protocol information over point-to-point links. PPP also defines an extensible Link Control Protocol, and proposes a family of Network Control Protocols (NCPs) for establishing and configuring different network-layer protocols.; This document defines the method for sending IPv6 packets over PPP links, the NCP for establishing and configuring the IPv6 over PPP, and the method for forming IPv6 link-local addresses on PPP links.; It also specifies the conditions for performing Duplicate Address Detection on IPv6 global unicast addresses configured for PPP links either through stateful or stateless address autoconfiguration.; This document obsoletes RFC 2472. [STANDARDS-TRACK]
RFC5075 - IPv6 Router Advertisement Flags Option: The IPv6 Neighbor Discovery's Router Advertisement message contains an 8-bit field reserved for single-bit flags. Several protocols have reserved flags in this field and others are preparing to reserve a sufficient number of flags to exhaust the field. This document defines an option to the Router Advertisement message that expands the available number of flag bits available. [STANDARDS-TRACK]
RFC5095 - Deprecation of Type 0 Routing Headers in IPv6: The functionality provided by IPv6's Type 0 Routing Header can be exploited in order to achieve traffic amplification over a remote path for the purposes of generating denial-of-service traffic. This document updates the IPv6 specification to deprecate the use of IPv6 Type 0 Routing Headers, in light of this security concern. [STANDARDS-TRACK]
RFC5175 - IPv6 Router Advertisement Flags Option: The IPv6 Neighbor Discovery's Router Advertisement message contains an 8-bit field reserved for single-bit flags. Several protocols have reserved flags in this field and others are preparing to reserve a sufficient number of flags to exhaust the field. This document defines an option to the Router Advertisement message that expands the number of flag bits available. [STANDARDS-TRACK]
