DHCPv6 Prefix-Length Hint Issues
RFC 8168, “DHCPv6 Prefix-Length Hint Issues”, is a Proposed Standard document published in May 2017 by T. Li, C. Liu, Y. Cui. The canonical text is published by the RFC Editor.
Abstract
DHCPv6 Prefix Delegation allows a client to include a prefix-length hint value in the IA_PD option to indicate a preference for the size of the prefix to be delegated, but it is unclear about how the client and server should act in different situations involving the prefix-length hint. This document provides a summary of the existing problems with the prefix-length hint and guidance on what the client and server could do in different situations.
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.
