How do you determine if a domain is hosted on an IP address?

We support the CIDR notation for subnets. For example x.x.x.x/8. See example below!

The Reverse IP Tool is now integrated in the new Domain Search interface. With the new interface you can search for domains on many different fields like name, MX/NS records and provider. See examples below!

Our DNS crawlers try to resolve every domain name every two weeks.
