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.

Find subdomains


This is a beta version of subdomain lookup tool, sorry for any bugs.
Subdomains lookup will be performed using DNS. If it fails, this tool will try to get information from search engines.
Enter domain name eg site.com without WWW. to find subdomains.
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.
