Use our core tools to diagnose network issues, verify ownership, and improve email and security reputation.
Each tool is optimized for fast results, privacy-friendly lookups, and clear explanations so you can act on what you learn.
Each tool answers a specific networking question. If you are troubleshooting a domain, start with DNS Lookup to confirm records, then use Reverse DNS to verify hostnames tied to the IP. If you need ownership or routing details, ASN Lookup tells you who announces the IP range and how traffic is routed across networks. For reputation checks, IP Blacklist can reveal if mail or security systems are flagging an address.
You can also chain tools together. For example, if a hostname resolves to an unexpected IP, run ASN Lookup to see which network is advertising it. If you suspect a VPN or proxy is involved, run Proxy Check before trusting geolocation or ownership results.
These tools are designed for quick diagnostics and easy explanations, so you can move from data to action without digging through raw records.
