About the What Is My IP
Tezmy's What Is My IP shows the public IP address your connection uses on the internet, the moment the page opens. With it you see whether it is IPv4 or IPv6, whether it is public, private or shared by your provider, its hostname (reverse DNS), your internet provider and network number, and the approximate city, region, country, coordinates and time zone linked to it, with a map link. A second part shows what your browser shares about your device: browser and version, system, device type, screen, languages, time zone, touch support, network speed estimate and more. Copy just the IP or every detail at once. A short explainer covers why other sites sometimes show a different address. Your IP is read from your own request and is never stored.

How to use the What Is My IP
- 1Open the page: your IP address appears at the top within a second.
- 2Press Copy IP (or Copy all details) for a support ticket, firewall rule or setting.
- 3Read the Location, Network and Device sections for the details behind it.
- 4Turn a VPN on or off and press Check again to see the address change.
What each detail means
- Version: IPv4 (four numbers) or IPv6 (groups of letters and numbers).
- Type: public addresses are what websites see; private ones (192.168.x.x, 10.x.x.x) exist only inside a home or office network.
- ISP and ASN: the company and network block that owns the address.
- Nearest data centre: the Cloudflare location that served this page, usually close to you.
- HTTP version and encryption: how your browser connected, such as HTTP/3 and TLS 1.3.
When you need your IP address
- IT support or a hosting company asks for it to allow access or fix a problem.
- Setting up remote desktop, a game server, a camera or a VPN.
- Adding your address to a firewall, email or database allow-list.
- Checking that a VPN or proxy really hides your address.
Why your IP address changes
Most home and mobile connections get a dynamic address that the provider can change when your router restarts or from time to time; businesses often pay for a static one. Switching between Wi-Fi and mobile data, joining another network or using a VPN also gives you a different public address. Your address is one clue to how you appear online, so build a strong sign-in with the Password Generator and protect it with the Hash Generator for testing. The URL Encoder & Decoder and the Base64 Encoder & Decoder help when you share addresses or headers with a support team.

Frequently asked questions
Why do other websites show a different IP address?
Usually because your connection has two addresses: an IPv4 one and an IPv6 one. Each site sees whichever your device used to reach it, so one can show IPv6 while another shows IPv4, and both are correct. VPNs, iCloud Private Relay and some browsers' privacy features can also route different sites through different servers, and mobile networks change addresses often.
What is the difference between IPv4 and IPv6?
IPv4 addresses look like 203.0.113.42 and there are only about 4 billion of them, so providers now share them. IPv6 addresses look like 2001:db8::1 and there are enough for every device on Earth. If this page shows an IPv6 address, your network supports IPv6.
Why is my location wrong?
IP location is only approximate. It usually shows where your internet provider's equipment or address block is registered, which can be a nearby city or even another region. Mobile data and VPNs make it less accurate still. It never shows your street or house.
What is the hostname or reverse DNS?
Many providers give each address a name, such as 81-2-3-4.broadband.example.net. It often reveals the provider and sometimes the area, and mail servers and network tools use it. Not every address has one, so the field can be empty.
What does “shared by your provider (CGNAT)” mean?
Some providers, especially mobile networks, give many customers one public IPv4 address using Carrier-Grade NAT. You then see an address from the 100.64.0.0 range inside the network, and websites see the provider's shared address. It can make hosting a game server or remote access harder.
Can someone find my home from my IP address?
Not your address. An IP shows roughly which provider and area you connect from. Only your internet provider knows which customer used an address at a given time, and they share that only when the law requires it.
How do I check if my VPN is working?
Note your IP and location here, turn the VPN on and press Check again. If the address, provider and location change to the VPN's, your traffic goes through the VPN. If you also see IPv6 from your own provider, your VPN may not cover IPv6.
Do you store my IP address?
No. The page asks our server for the address your own request came from and shows it only to you. We don't save it, log it with anything else or share it. Device details are read in your browser and never sent to us.
