Find other IP information
Searching the WHOIS IP address database helps find out who an IP address is registered to and provides other data once you have an IP address. However, in some cases, you may first need to find an IP address from a domain to search for it in the WHOIS lookup tool.
To find the IP address from a domain, look up the domain in the domain name system using the DNS lookup tool. To find a domain from an IP address, use reverse IP address lookup or reverse DNS lookup .
