Attributes

port[R]

The port on this target host of this service.

The range is 0-65535.

priority[R]

The priority of this target host.

A client MUST attempt to contact the target host with the lowest-numbered priority it can reach; target hosts with the same priority SHOULD be tried in an order defined by the weight field- The range is 0-65535- Note that it is not widely implemented and should be set to zero-

target[R]

The domain name of the target host.

A target of “-” means that the service is decidedly not available at this domain-

weight[R]

A server selection mechanism-

The weight field specifies a relative weight for entries with the same priority- Larger weights SHOULD be given a proportionately higher probability of being selected- The range of this number is 0-65535- Domain administrators SHOULD use Weight 0 when there isn't any server selection to do, to make the RR easier to read for humans (less noisy)- Note that it is not widely implemented and should be set to zero-
