IP Lookup — Your IP Address, Location and Network Details
See your own IPv4 and IPv6 instantly, or look up any IP address or domain: geolocation, ISP, ASN, reverse DNS, hosting detection, VPN and proxy flags, and blacklist status.
What an IP lookup can and cannot tell you
Every device on the internet is reachable through an IP address, and that address carries a surprising amount of public context: which network operator announces it, which organisation the block is allocated to, roughly where that block is used, and whether it belongs to a datacentre rather than a home connection. This tool shows your own address by default and will look up any other address or domain on request.
What you get back
- Your IPv4 and IPv6 — both are detected separately, since many connections have one and not the other.
- Geolocation — country, region, city, postal code, coordinates and timezone, with a map.
- Network — the ISP, the organisation holding the block and the ASN that routes it.
- Reverse DNS — the PTR hostname, which often reveals the hosting provider and the server's role.
- Connection type — flags for mobile networks, datacentre or hosting ranges, and known proxy or VPN exits.
- Reputation — DNSBL blacklist status across major lists, which matters if you send email from the address.
How accurate is IP geolocation?
Country-level accuracy is high, typically 95 to 99 percent. City-level accuracy is much softer — commonly 50 to 80 percent — because databases map an address block to where the ISP registered it, not to where the device physically is. Mobile networks often report the location of the gateway rather than the handset, and a VPN reports the exit node. An IP address is a network identifier, not a home address.
Finding where a website is hosted
Enter a domain instead of an IP and the tool resolves it first, then looks up the resulting address. The organisation and reverse DNS fields usually name the hosting provider directly, and the location tells you which region the site is served from — the single biggest factor in response time for a local audience.
Frequently asked questions
What is my IP address?
Your public IP address is shown at the top of the tool as soon as the page loads, for both IPv4 and IPv6 where your connection supports them. This is the address websites see when you visit them — not the private address your router assigns inside your home or office network.
How do I look up a different IP address?
Type any IPv4 address, IPv6 address or domain name into the lookup box and run the check. Entering a domain resolves it to its server address first, which is how you find out where a website is hosted.
How accurate is IP geolocation?
Country-level results are accurate roughly 95 to 99 percent of the time. City-level results are far less reliable, typically 50 to 80 percent, because geolocation databases map network blocks to registered ISP locations rather than to physical devices. VPNs, mobile networks and satellite connections shift the result to the network gateway.
What is an ASN?
An Autonomous System Number identifies the network that announces an IP range to the global routing table. ISPs, hosting companies and large organisations each operate one or more. The ASN tells you who controls the address at the routing level, which is often more useful than the organisation name when investigating traffic.
Can someone find my home address from my IP?
No. A public IP lookup returns the approximate area your ISP registered the address block to, along with the ISP name. Linking an address to a specific subscriber requires records only the ISP holds, which are released to law enforcement under legal process.
What does it mean if my IP is blacklisted?
A DNSBL listing means a mail-reputation service has flagged the address, usually because spam was sent from it or from a neighbouring address on a shared range. Mail from a listed IP is frequently rejected or filtered. Each list publishes its own delisting procedure once the underlying cause is fixed.
