NAPTR – Naming Authority Pointer

The NAPTR (Naming Authority Pointer) record specifies a regular expression based rewrite rule that, when applied to an existing string, produces a new domain label or URI (Universal Resource Identifier). This allows DNS to be used to look up services for a wide variety of resource names that are not in domain name syntax. For more information, see RFC 2915.
