Detailed Domain Profiles
The DomainTools Whois results page goes beyond traditional Whois lookup tools by providing a detailed profile of the specified domain.

Reverse IP and Reverse Name Server
- Reverse IP: This feature shows what other domains are hosted on the same IP address, helping to identify potential security threats or malicious activities clustered on a single IP.
- Reverse Name Server: This feature lists other domains served by the selected name server, which can help in identifying domains that might be managed by the same entity.
