URI record explained

In the Domain Name System, a Uniform Resource Identifier (URI) record (RFC 7553) is a means for publishing mappings from hostnames to URIs.

Record format

The URI record is expressed in a master file in the following format:

where:

service: the symbolic name of the desired service.

proto: the transport protocol of the desired service; this is usually either TCP or UDP.

name: the domain name for which this record is valid, ending in a dot.

TTL: standard DNS time to live field.

class: standard DNS class field (this is always IN).

priority: the priority of the target host, lower value means more preferred.

weight: A relative weight for records with the same priority, higher value means more preferred.

target: This field holds the URI of the target, enclosed in double-quote characters ('"'), where the URI is as specified in RFC 3986
