IPv6-Only Preferred Option for DHCPv4
RFC 8925, “IPv6-Only Preferred Option for DHCPv4”, is a Proposed Standard document published in October 2020 by L. Colitti, J. Linkova, M. Richardson, T. Mrugalski. It updates RFC 2563. The canonical text is published by the RFC Editor.
Abstract
This document specifies a DHCPv4 option to indicate that a host supports an IPv6-only mode and is willing to forgo obtaining an IPv4 address if the network provides IPv6 connectivity. It also updates RFC 2563 to specify DHCPv4 server behavior when the server receives a DHCPDISCOVER not containing the Auto-Configure option but containing the new option defined in this document.
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.
