Get access to our Reverse DNS (IP to Domain) database in Excel CSV format below. It contains IPv4 and IPv6 address mappings to all known domain names. A domain name can resolve to multiple IP addresses, and an IP address can reverse-resolve to multiple domain names. The same data can be used to map IP addresses to domain names as well as domain names to IP addresses.

Database Contents

This database contains IPv4 and IPv6 addresses with the domain names pointing to them. Each line contains one IP address to domain name mapping. Since some domains resolve to multiple IP addresses, these have multiple entries in the database.

Purchase & Update Prices

When you first purchase the database, the purchase price applies. If you later buy an update and check out with the same user account, the update price will apply.
