Discover relationships among web sites, domain owners and IP addresses with Name Server Reports, Reverse IP lookups and Reverse Whois Reports.

Find domains to register or buy with Domain Suggestions and Domain Search APIs.

Could not get this to work. It keeps complaining "Unauthorized access to API service"

The support site does not work: you can create a ticket but then you cannot access your own ticket anymore.

Then the people from domaintools / nameintel do not follow up my emails to their support address.

Sigh...
