This document requests the allocation of an IPv4 /10 address block tobe used as Shared Address Space to accommodate the needs of Carrier-Grade NAT (CGN) devices. It is anticipated that Service Providerswill use this Shared Address Space to number the interfaces thatconnect CGN devices to Customer Premises Equipment (CPE).
Shared Address Space is distinct from RFC 1918 private address spacebecause it is intended for use on Service Provider networks.However, it may be used in a manner similar to RFC 1918 privateaddress space on routing equipment that is able to do addresstranslation across router interfaces when the addresses are identicalon two different interfaces. Details are provided in the text ofthis document.
This document details the allocation of an additional special-useIPv4 address block and updates RFC 5735. This memo documents an Internet Best Current Practice.
This memo reiterates the assignment of an IPv4 address block(192.0.0.0/24) to IANA. It also instructs IANA to restructure itsIPv4 and IPv6 Special-Purpose Address Registries. Upon restructuring,the aforementioned registries will record all special-purpose addressblocks, maintaining a common set of information regarding each addressblock.
This memo updates the IANA IPv4 and IPv6 Special-Purpose AddressRegistries to address issues raised by the definition of a "global"prefix. It also corrects several errors in registry entries toensure the integrity of the IANA Special-Purpose Address Registries.
This memo updates RFC 6890.
