A DNS Resource Record for Encoding Dynamic Host Configuration Protocol Information
RFC 4701, “A DNS Resource Record for Encoding Dynamic Host Configuration Protocol Information”, is a Proposed Standard document published in October 2006 by M. Stapp, T. Lemon, A. Gustafsson. It has since been updated by RFC 5494. The canonical text is published by the RFC Editor.
Abstract
It is possible for Dynamic Host Configuration Protocol (DHCP) clients to attempt to update the same DNS Fully Qualified Domain Name (FQDN) or to update a DNS FQDN that has been added to the DNS for another purpose as they obtain DHCP leases. Whether the DHCP server or the clients themselves perform the DNS updates, conflicts can arise. To resolve such conflicts, RFC 4703 proposes storing client identifiers in the DNS to unambiguously associate domain names with the DHCP clients to which they refer. This memo defines a distinct Resource Record (RR) type for this purpose for use by DHCP clients and servers: the "DHCID" RR. [STANDARDS-TRACK]
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.
