The 'PTR' (Pointer) Record

The pointer to a domain for an address represented in the NAME field. Very common, but know that not all domains have PTR records pointing to them.

Example: To find the domain for '68.123.54.6'
Query Name must be '6.54.123.68.IN-ADDR.ARPA'

Example: To find the domain for 'EEAA.32.A43.0.5300.A0.76.A43D'
Query Name must be 'D.3.4.A.6.7.0.0.0.A.0.0.0.0.3.5.0.0.0.0.3.4.A.2.3.A.A.E.E.IP6.INT'
