How do I check a reverse PTR record

How do I check a reverse PTR record

From linux type:

dig -x xx.yy.zz.aa

xx.yy.zz.aa = The IP address you’re trying to resolve

You’ll get an answer with your authority of aa.zz.yy.xx.in-addr.arpa and server resolving to this address.

From windows type in command prompt  : nslookup xx.yy.zz.aa

Testing reverse dns on Google’s DNS server of 8.8.8.8:

dig -x zz.yy.xx.aa @8.8.8.8

or nslookup zz.yy.xx.aa 8.8.8.8 from Windows
