As with any investigation, domain/host investigation is only as good as the resources it uses. We have therefore amassed what is one of the world’s largest private domain databases – 765+ million registered and expired domain names and counting!
It covers all gTLDs (.com, .net, .info, .biz, .org), new gTLDs (.club, .city, .shop, etc.), and ccTLDs (.uk, .de, .ca, etc.) which include about 90% of the domains registered in all ccTLDs.

Combining that with a team of highly qualified experts and one of the world’s largest private domain databases, we can offer you flexible and ever-improving domain services:

All Relations Lookup

A domain lookup that allows you to search for the domain’s NS records, A and AAAA records, MX records /if available/, Whois details and lists of all related domains by NS, IP, MX or host.

It offers you unique search interconnectedness among all these results that enables you to find relations among any of the domains or domain data above by simply clicking on any result.

Related Names Lookup

You can find related domains by searching a keyword or a phrase in our active domain database and get a list of all the domains that contain your search.

Reverse Whois

This lookup allows you to find all domain names owned by the same organization or natural person by searching their name, email address, or other identifiers from a Whois record.

Reverse IP

If you search an IP address the lookup provides you with all the domains on the same IP.

Reverse NS & MX

You can find all domains sharing the same nameservers with Reverse NS. Reverse MX allows you to find all domains using the same MX records.

Reverse NS* & MX*

This new lookup works like Reverse NS & MX, but allows you to find a much broader range of results of connected domains by NS and MX. Why not check it out now!

Archive DNS Data

We can provide archive DNS data on request. Simply write to us with your query and we’ll get back to you with more details.
