# What Is My IP Address? — Full IP, ASN, Registry and Leak Report > Your public IPv4 and IPv6 address with the routing, registry, blocklist and VPN-leak detail behind it. Your public IP address is the one your connection presents to every site you visit, and it is shown here the moment the page loads — alongside the autonomous system that announces it, the registry record for its block, its reverse DNS name, an approximate location, whether six mail blocklists carry it, and whether your IPv6 or WebRTC configuration leaks a second address around a VPN. Enter any other address to run the same report against it. **URL:** https://convertto.tech/t/what-is-my-ip **Category:** Network Tools (https://convertto.tech/c/network-tools) **Privacy:** Uses a server request **Cost:** Free, no sign-up **Last updated:** 2026-08-01 ## Key facts - **Privacy:** Uses a server — the address you enter is sent to perform the lookup - **Routing data:** Team Cymru IP-to-ASN — the global routing table, not a vendor guess - **Registry data:** RDAP, direct from the RIR that allocated the block - **Accuracy:** Location is city-level at best; ASN and registry data are exact - **API:** curl /api/net/ip?format=text — no key, no account - **Cost:** Free, unlimited, no sign-up ## How to use 1. Open the page — your address, location and network appear without pressing anything. 2. Read the VPN and proxy signals to see what a website would infer about you. 3. Run the WebRTC leak test to check whether a second address is exposed. 4. Enter any other IP or hostname to run the same report against it. ## FAQ ### Why is my IP location wrong? Geolocation maps an address block to wherever its operator registered it, which is often a regional office rather than your street. Mobile networks route thousands of subscribers through a handful of gateways, and a VPN deliberately reports its exit server. The autonomous system and registry data on this page are exact; the city is the only part that is a guess. ### What is an ASN and why does it matter? An autonomous system number identifies the network that announces your address to the rest of the internet — usually your ISP. It is the most reliable thing on this page, because it comes from the routing table itself. Sites use it to tell a home broadband customer from a datacentre, which is how VPN blocking mostly works. ### Can this tell me if I am really behind a VPN? It shows you the signals, not a verdict. A timezone that disagrees with the IP country, a hosting network rather than a consumer ISP, and a WebRTC address that differs from your routed one are the three cheap checks a website runs. Any one of them can fire on an honest connection, which is exactly why they are listed separately rather than totalled into a score. ### What is a WebRTC leak? WebRTC gathers every address your machine can be reached on so that peer connections work. For years that handed sites the real address of anyone behind a VPN. Browsers now replace local addresses with mDNS names by default, so a clean result usually means the browser is doing its job — but a public address that differs from your routed one is a genuine leak. ### Why does IPv6 matter for privacy? Many VPNs tunnel IPv4 and quietly ignore IPv6. If both stacks work and only one address changes when you connect, every IPv6-capable site sees your real address regardless of the tunnel. That is why both are probed separately here. ### My IP is on a blocklist — what now? Blocklists index the address, not you, and on a residential connection it is usually a neighbour on the same dynamic pool or an infected device on your network. Each list publishes a delisting form; use the abuse contact from the registry record if the address is one you actually control. ### Is my IP address personal information? Under GDPR it is treated as personal data, and every server you connect to sees it because that is how replies are routed. On its own it identifies an ISP and an approximate area, not a person — connecting it to a name needs subscriber records only the ISP holds. ### Can I look up someone else's IP address? You can run the same report on any public address using the box at the top. What comes back is network ownership, not identity: the ISP, the registered block, the abuse contact and an approximate location. Nothing here reveals who is using the address. ## Sources - [RFC 791 — Internet Protocol](https://www.rfc-editor.org/rfc/rfc791) — IETF - [RFC 8200 — IPv6 Specification](https://www.rfc-editor.org/rfc/rfc8200) — IETF - [RFC 7239 — Forwarded HTTP Extension](https://www.rfc-editor.org/rfc/rfc7239) — IETF - [RFC 9083 — RDAP JSON Responses](https://www.rfc-editor.org/rfc/rfc9083) — IETF - [Team Cymru IP-to-ASN Mapping](https://team-cymru.com/community-services/ip-asn-mapping/) — Team Cymru ## Related tools - [DNS Lookup](https://convertto.tech/t/dns-lookup): Pull every DNS record for a domain at once, check SPF and DMARC, and compare four public resolvers. - [SSL Certificate Checker](https://convertto.tech/t/ssl-certificate-checker): Open a real TLS handshake to any host and read the certificate it is serving right now. - [HTTP Header Checker](https://convertto.tech/t/http-header-checker): Follow every redirect, grade the security headers and read the cookie and caching settings. - [Open Graph Preview](https://convertto.tech/t/open-graph-preview): Render your share card the way each platform really draws it, with the og:image measured. - [WHOIS / RDAP Domain Lookup](https://convertto.tech/t/whois-lookup): Registration dates, transfer locks and status codes in plain English, cross-checked against live DNS. - [AI Photo Redactor](https://convertto.tech/t/ai-photo-redactor): Detect people, faces, plates and screens with an object-detection model in your browser, then blur or black them out. - [Connection & Network Information](https://convertto.tech/t/connection-info): See what your browser reports about the network: connection type, downlink estimate and round-trip time. - [CSV Data Anonymiser](https://convertto.tech/t/data-anonymiser): Mask, hash or replace personal data in a CSV so it can be shared safely.
