PTRDNAME A <domain-name> which points to some location in the

domain name space.

PTR records cause no additional section processing. These RRs are used

|
in special domains to point to some other location in the domain space.
|
|
These records are simple data, and don't imply any special processing
|
|
similar to that performed by CNAME, which identifies aliases. See the
|
|
description of the IN-ADDR.ARPA domain for an example.
