But does a PTR record exist? The double reverse lookup should succeed so long as there is a valid A <-> PTR pair. Regardless of whether it was launched into from another A or CNAME or IP. Unless I'm way off base here, it goes presented name -> IP lookup -> PTR lookup -> IP lookup. If the two IP lookups match, the test is passed.
