Online DNS lookup Full DNS lookup, find all subdomains
Law of Available Space: If there are n bytes in a crucial software program, the available space for its convenient storage or loading is equal to n-1 bytes.

PTR record lookup (Reverse DNS lookup).

Enter IP address or hostname to find the PTR record.
Please note that PTR record is commonly needed only for mailservers.
If you don't have a valid PTR record, you may not be able to send email to some sites.
If you don't know your mailserver ip address or FQDN, use our full DNS report tool first.

This is a beta version of subdomain lookup tool, sorry for any bugs.

If you are looking for subdomains of site.com, subdomains lookup tool will return
subdomain.site.com, lookup.subdomain.site.com and subdomain-site.com, lookup.subdomain-site.com also.
