URI record
In the Domain Name System, a Uniform Resource Identifier (URI) record (RFC 7553) is a means for publishing mappings from hostnames to URIs.
01Record format
The URI record is expressed in a master file in the following format:
_service._proto.name. TTL class URI priority weight target.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
02An example DNS URI resource record
