Check your public IP or look up any IPv4, IPv6 or hostname for location, ISP and full connection details.
Columbus, OhioAn IP address (Internet Protocol address) is a unique numerical label assigned to every device connected to the internet or a local network. It serves two essential functions: identifying your device and providing its network location so data packets can be routed correctly across the internet. Every time you visit a website, stream a video or send a message, your IP address is embedded in those requests so the response knows exactly where to return. Without IP addresses, routing data between billions of devices would be impossible — they are the foundation of how the internet works.
IP addresses exist in two versions. IPv4 uses 32-bit addresses in the familiar dotted decimal format (e.g. 203.0.113.45), providing roughly 4.3 billion unique addresses. IPv6 uses 128-bit hexadecimal addresses (e.g. 2001:db8::1), providing a practically unlimited supply to accommodate the ever-growing number of internet-connected devices. Use our DNS Lookup tool to see how domain names map to IP addresses in real time.
A public IP address is assigned by your Internet Service Provider and is the address that the wider internet sees when you connect to any online service — it is exactly what this page detects and displays. A private IP address is assigned by your router and exists only within your local network. Typical private ranges are 192.168.x.x, 10.x.x.x and 172.16–31.x.x. Private addresses are never visible to the public internet — your router translates between them and your public IP using a process called NAT (Network Address Translation). To investigate which organisation owns any public IP, use our ASN Lookup tool.
Your public IP address can reveal your approximate city or region, your Internet Service Provider, your AS number, your timezone, and whether your connection is residential, mobile, a data centre or a known VPN. It does not reveal your exact street address, your full name, your browsing history or any personal account information. The location accuracy depends on how your ISP has registered its IP ranges — for mobile networks and large ISP blocks the location can be off by tens or hundreds of kilometres. To check what security headers a website sends, try our HTTP Headers Checker. To verify whether a specific port is open, use the Port Checker.
These flags indicate the likely nature of the connection associated with an IP address. Proxy / VPN means the IP is registered to a VPN service, commercial proxy, Tor exit node or anonymisation network. Hosting / Data Centre means the IP belongs to a cloud provider or hosting company (such as Amazon AWS, Google Cloud or Hetzner) rather than a typical residential or business broadband connection. These flags are widely used by fraud detection systems to distinguish human users from automated traffic. To investigate the full network that owns an IP, use our ASN Lookup to find the Autonomous System number, operator name and the full IP range it covers.
Yes — use the search box at the top of this page to look up any IPv4 address, IPv6 address or hostname. When you enter a hostname (like example.com), the tool automatically resolves it to an IP address first using DNS, then returns the full geolocation and network details. For a full view of a domain's DNS configuration including its A, MX and TXT records, use our DNS Lookup tool. To go in the other direction — from an IP back to a hostname — use our Reverse DNS tool.
Most home broadband connections use a dynamic IP address assigned by the ISP via DHCP. This can change when you restart your router, after the lease period expires, or when your ISP rebalances its pools. Mobile connections change IP addresses even more frequently as you move between cell towers. Businesses that run servers typically pay for a static IP address that never changes. After confirming a static IP or domain, use our SSL Certificate Checker to verify the HTTPS certificate on that host is valid and trusted.
Use our Port Checker tool, which tests whether any TCP port on your IP or any other host is publicly reachable. Common ports include 80 (HTTP), 443 (HTTPS), 22 (SSH), 25 and 587 (email), 3306 (MySQL) and 3389 (Remote Desktop). This is especially useful after configuring a firewall rule or port forwarding on your router to confirm the change has taken effect. You can also use our Ping Test to verify basic connectivity to any host.
An ASN (Autonomous System Number) is a unique identifier assigned to a collection of IP address ranges under the control of a single organisation — typically an ISP, a large company or a cloud provider. Every public IP belongs to exactly one Autonomous System. The Full IP Details panel above shows your ASN and the organisation name. For a deeper investigation of any ASN — including all IP ranges it owns, its registered country and its peering relationships — use our ASN Lookup tool.
IPv4 uses 32-bit addresses written as four groups of numbers separated by dots, such as 192.0.2.1. The total pool of roughly 4.3 billion addresses was exhausted around 2011. IPv6 uses 128-bit addresses written in eight groups of hexadecimal digits, such as 2001:0db8:85a3::8a2e:0370:7334 — providing a practically inexhaustible supply. Both protocols are currently in active use simultaneously via dual-stack networking. To check whether a domain supports both IPv4 and IPv6, run a DNS Lookup and look for both A (IPv4) and AAAA (IPv6) records. For granular subnet calculations across either protocol, use our Subnet Calculator.
No. Your IP is detected in real time purely to display the result on this page. It is not stored, logged, linked to any user profile or used for advertising purposes on our servers. The geolocation data is fetched live from a third-party API on each page load and is not retained. The lookup runs fresh every time you visit — there is no cached result tied to your address.
Every web server you connect to logs your IP address for security monitoring, abuse prevention and analytics. Many services use your IP to infer your approximate location for content localisation — showing prices in your local currency or auto-selecting your language. Security systems compare your IP against threat intelligence databases to detect suspicious logins or automated traffic. CDNs use your IP to route you to the nearest server, reducing latency. To see the full HTTP request details and security headers a web server sends when you connect to it, use our HTTP Headers tool. For full domain registration and ownership details, try our WHOIS Lookup.
