About NetworkWhois
NetworkWhois provides a growing set of free network tools built for real-world troubleshooting. Run IP WHOIS lookups to identify ownership and allocation details, check reverse DNS (PTR) when you need hostname context, and verify whether an IP is listed on common spam blacklists. For email teams, you can validate domain authentication signals like MX, SPF, DKIM, and DMARC, and for operations work you can inspect SSL certificates and test IPv6 connectivity. Most tools are usable instantly and the outputs are designed to be easy to copy and share in tickets or incident channels.
