Abstract

The Dynamic Host Configuration Protocol (DHCP) provides a mechanism for host configuration that includes dynamic assignment of IP addresses and fully qualified domain names. To maintain accurate name-to-IP-address and IP-address-to-name mappings in the DNS, these dynamically assigned addresses and fully qualified domain names (FQDNs) require updates to the DNS. This document identifies situations in which conflicts in the use of fully qualified domain names may arise among DHCP clients and servers, and it describes a strategy for the use of the DHCID DNS resource record (RR) in resolving those conflicts.
