Port Control Protocol Anycast Addresses
RFC 7723, “Port Control Protocol Anycast Addresses”, is a Proposed Standard document published in January 2016 by S. Kiesel, R. Penno. The canonical text is published by the RFC Editor.
Abstract
The Port Control Protocol (PCP) anycast addresses enable PCP clients to transmit signaling messages to their closest PCP-aware on-path NAT, firewall, or other middlebox without having to learn the IP address of that middlebox via some external channel. This document establishes one well-known IPv4 address and one well-known IPv6 address to be used as PCP anycast addresses.
What “Proposed Standard” means
An entry-level standards-track specification: stable, peer-reviewed and a solid basis for implementation, though it may still evolve before becoming an Internet Standard.
