Your internet provider

Checking your connection…

Asking our server how your connection looks from the internet.

The location is where your provider registers this address, often a nearby city, not your home.

How to use What Is My ISP

  1. Open the page: it checks your connection straight away.
  2. Read your provider’s name at the top, with the brand people know when the registered name is a company’s legal name.
  3. Check the details: your IP address, network number, approximate location and the Cloudflare data center you reached.
  4. Turn your VPN, iCloud Private Relay or Wi-Fi on or off and click Check again to see what changes.
  5. Copy the details if support asks for them.

How it works

Every address on the internet belongs to a network, and every network is registered to a company. When this page loads, it asks the QuickFixBase server, which runs on Cloudflare, how your connection looks from the internet. Cloudflare already knows your IP address and the network it belongs to, so no outside service is asked. The answer comes straight back to you and isn’t stored or logged.

Detail What it means
Provider (ISP) The company that owns the network your IP address belongs to, as registered
IP address Your public address, shared by every device on your home network
Network number The network’s Autonomous System Number (ASN), like AS7922
Approximate location Where the provider registers the address, often a nearby city
Cloudflare data center The Cloudflare city you reached, as an airport code like ORD (Chicago)
Connection HTTP version, encryption, and the round trip to Cloudflare when it’s measured

When the provider looks wrong

  • VPN, iCloud Private Relay, Cloudflare WARP: your traffic leaves through their network, so you see it instead of your provider. The result says so when the network belongs to a VPN or cloud company.
  • Work or school network: you see the organization’s provider, or its security service.
  • Phone on mobile data: you see the carrier. Connect to Wi-Fi and check again to see your home provider.
  • Smaller providers: some rent a bigger company’s network, so its name shows. The network number is still yours to quote to support.
  • Legal names: networks are registered under company names. Comcast shows as Xfinity and Charter as Spectrum, with the registered name underneath.

Using it to check a VPN

Check once with the VPN off and once with it on. If the provider and IP address change, the VPN is working. If they stay the same, your traffic isn’t going through the VPN.

Your IP address and privacy

Your public IP address is shared by every device on your home network, and websites see it whenever you visit. It shows your provider and a rough area, not your street or name. Many providers change it from time to time, and restarting your router sometimes gets you a new one.

Questions

How do I find out who my internet provider is?

Open this page: it names the provider your connection comes from, read from the network your IP address belongs to. On a phone, turn off Wi-Fi to see your mobile carrier instead. Your bill, your router’s label and your provider’s app name it too.

Why does it show the wrong internet provider?

A VPN, iCloud Private Relay, Cloudflare WARP or a work network sends your traffic through someone else’s network, so you see theirs. Turn them off and check again. Smaller providers sometimes use a bigger company’s network; then the network’s owner is shown.

Is the location my home address?

No. It’s where your provider registers this IP address, often a nearby city or the provider’s hub, sometimes far away. Nobody can find your home from it; only your provider knows which customer had an address at a given time.

What is an ASN?

An Autonomous System Number identifies a network on the internet, like AS7922 for Comcast. Each provider has one or more. Support teams and network tools use it to know exactly which network an address belongs to.

Can my internet provider see what websites I visit?

It can see which sites you connect to, but not the pages or what you type on sites that use HTTPS. A VPN or encrypted DNS hides the sites from your provider; the VPN company can see them instead.

Why do I see an IPv6 address instead of IPv4?

Many providers give you both kinds. Your browser picks one for each connection, usually IPv6 when it works, and this page shows the one it used. Both belong to the same provider.
