What Is an ISP?

An internet service provider is the company that connects you to the internet and assigns you a public IP address. Every public IP is leased to an operator, so looking up the owner of your address tells you which network you are connected through right now.

The name shown is the registered owner of the IP block. That is usually your provider, but on mobile, business or resold connections it can be a parent network or a wholesale carrier instead of the brand you pay.

What Is an ASN?

An autonomous system number (ASN) is a unique identifier for a network operator. Each operator groups its IP addresses into an autonomous system and announces it under one ASN, which is how routers across the internet decide where to send traffic destined for those addresses.

Your IP address identifies a single connection. The ASN identifies the entire network it sits inside, and a single ASN can hold many thousands of addresses.

Why Your Provider Name Might Look Off

If the organisation above is not the brand you signed up with, one of these is usually why:

  • Reseller: your provider rents capacity from a larger network that owns the IP block.
  • Mobile carrier: phone networks route through carrier gateways registered to the parent operator.
  • Hosting or cloud: if you are on a VPN, proxy or cloud server, you see that provider, not your home ISP.
  • Transit provider: some blocks are registered to the upstream company that carries the traffic.

Frequently Asked Questions

What is my ISP?
Your ISP (internet service provider) is the company that connects you to the internet, such as your home broadband, fibre or mobile provider. The name above is the organisation that owns the IP address your connection is using right now.
What is an ASN?
An ASN (autonomous system number) is a unique ID assigned to a network operator, like AS15169 for Google. Each operator announces the blocks of IP addresses it controls under its ASN, which is how the rest of the internet knows where to route traffic for those addresses.
Why does my ISP show a different company than I expected?
The name reflects whoever owns the IP block, which is not always your retail brand. It can show a hosting or cloud provider, a mobile carrier, a wholesale network your provider resells, or the upstream transit company that carries the traffic.
Can my ISP see what I do online?
Your ISP can see which sites and servers you connect to, and the content of any unencrypted traffic. HTTPS hides the contents of the pages you load, but not the domains. A VPN hides the destinations from your ISP by routing your traffic through its own servers first.
How do I find out who my ISP is?
This page detects it from your IP address. You can also check your internet bill, your contract, or the brand on your router. The owner of the IP and the brand you pay may differ when your provider resells another network.
Is my ASN the same as my IP address?
No. Your IP address identifies a single connection, while the ASN identifies the whole network that the IP belongs to. Many thousands of IP addresses can sit inside one ASN.
