Reverse DNS Checker

This tool will help you to check reverse dns records.

Let’s use the addresses you enter as the server.(Paste anyting. We will catch the first 50 valid ipv4s.)

Hide “name”, “rdata”, “type”, “ttl”, “rdlength” and “class” in results.

strict query mode means that if the hostname that was looked up isn’t actually in the answer section of the response, script will return an empty answer section, instead of an answer section that could contain CNAME records.

if we should set the recursion desired bit to 1 or 0.

request DNSSEC values, by setting the DO flag to 1; this actually makes the resolver add a OPT RR to the additional section, and sets the DO flag in this RR to 1.

set the DNSSEC AD (Authentic Data) bit on/off.

set the DNSSEC CD (Checking Disabled) bit on/off
