The URI record is expressed in a master file in the following format:
_service._proto.name. TTL class URI priority weight target.
- 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
