Your public IP address

What is my IP address?

Your IP address is the unique number that identifies your connection on the Internet, and IPKit is a free IP checker that shows it to you instantly the moment this page loads. Every website you visit, every app you use, and every online service you connect to sees this address, because it is how the Internet knows where to send data back to you. The IP address shown at the top of this page is your public IP: the address assigned by your Internet provider or mobile carrier that represents you on the open Internet. It is different from the private IP address your router gives your device at home (usually something like 192.168.1.x), which only exists inside your local network. When people search for "what is my IP", "check my IP", or "find my IP address", this public address is the one they are looking for.

Why would I need to check my IP?

Checking your IP address is one of the most common tasks in everyday tech life. Support agents ask for it when diagnosing connection problems. Servers and firewalls need it when you whitelist your home or office for remote access. Gamers use it for hosting sessions and port forwarding. Remote workers check it to confirm their VPN is actually connected, because when the VPN is on, your displayed IP, location, and provider all change. Website owners use an IP address lookup to understand where traffic comes from, and developers check what address their API requests arrive from. With IPKit you get the answer in one second, with a copy button, your connection type (IPv4 or IPv6), your approximate location, and your Internet provider with its network number.

IPv4 vs IPv6: which one am I using?

There are two versions of IP addresses in use today. IPv4 is the classic format made of four numbers separated by dots, such as 203.0.113.25, and it is still the most common. IPv6 is the newer, much longer format written in hexadecimal groups separated by colons, created because the world ran out of IPv4 addresses. IPKit detects which version your connection is using and shows it as a chip next to your address. The IP lookup and converter tools support both versions fully, including expanding and compressing IPv6 addresses and converting between IPv4 and its binary, decimal, and hexadecimal forms.

How accurate is IP location?

An honest IP checker tells you the truth: IP-based location is an estimate of where your network connects to the Internet, not your exact address. Country-level results are usually reliable, city-level results are often close but can be wrong, and the location may reflect your Internet provider's equipment, your mobile carrier's gateway, your company's head office, or your VPN server rather than where you are sitting. IPKit labels every result with its confidence level (country, region, or city), shows the accuracy radius when available, and never pretends to know your street address, because no IP tool honestly can. All location data comes from a local database on our own server, so your lookups are fast and are never forwarded to third-party services.

A complete IP address lookup and network toolkit

IPKit goes far beyond a simple "what is my IP" page. Enter any public IPv4 or IPv6 address into the IP lookup and you get its approximate location, time zone, coordinates, the autonomous system (ASN) and organization that operate the network, and the address in every technical format. The reverse DNS tool finds the PTR hostname behind an address, and the RDAP lookup fetches official registration records from the five regional Internet registries: ARIN, RIPE NCC, APNIC, LACNIC, and AFRINIC. For network professionals and students there is a full set of calculators: a CIDR calculator that gets /31 and /32 right, a subnet calculator that splits networks by required subnets or hosts, a range calculator for CIDR-to-range conversion and overlap checks, and converters between binary, decimal, hexadecimal, and IPv6 forms. You can also inspect the safe HTTP headers your browser sends and see your device details exactly as websites detect them. Every result can be copied, downloaded as TXT or JSON, printed to PDF, or shared through an expiring link.

Free, private, and mobile friendly

IPKit is free with no ads and no trackers. It works without an account, and the location disclaimer on every result means you always know what the data can and cannot tell you. Creating a free SmartKit account adds a personal dashboard with your lookup history and one-tap re-run, higher limits for shares and exports, and quick access to all nine tools. Whether you are on a phone, a tablet, or a desktop, every page, calculator, and report is designed mobile-first, so checking your IP or subnetting a network works just as comfortably on a small screen as on a big one.
