What this site provides
The site includes tools for checking your public IP address, looking up any public IPv4 or IPv6 address, identifying ASN routing context, checking MAC address vendor prefixes, testing IPv6 reachability, checking WebRTC exposure, and measuring internet speed with M-Lab NDT7.
How results are produced
Results come from public network data, browser APIs, Cloudflare request metadata, and third-party diagnostic endpoints. IP geolocation is approximate and normally identifies a network, ISP, VPN exit, proxy, or data-center location rather than a precise physical address.
Editorial standards
Tool pages are written to explain what each diagnostic result means, where the data can be uncertain, and which related checks can help confirm a result. Content is reviewed when tools change or when data-source behavior needs clearer explanation.

For your current network, open What Is My IP. For a specific address, use IP Lookup. For routing ownership, use ASN Lookup.
