This is your internet provider, as every site sees it.
Every site you open can look up the company behind your connection in an instant. This page shows you the same answer: your provider, its network, and the kind of line sites take it for.
The provider sites see
Amazon.com, Inc.
AS16509 · United States
This address sits in a datacenter, so it belongs to a server rather than a home or mobile line. On a VPN, a proxy or a work network that sends traffic through the cloud, the company above runs that server and your own provider stays hidden behind it. Turn the service off and reload this page to see your own.

What the lookup shows
Your provider is the company that connects you to the internet and holds the address your traffic comes from. Every address carries a public record, and the card above is yours.
Provider
The company the address block is registered to. That is often the parent company or the network behind the brand on your bill.
Network (ASN)
The autonomous system number of the provider's network. Every public address is announced under one of these numbers, and sites group traffic by them.
How sites classify it
Home or business line, mobile carrier, datacenter, VPN, proxy or Tor. Fraud and security systems decide how far to trust a visit partly on this.
Reverse DNS
The name the provider gave your address. It often carries the provider's domain and hints such as static, dsl or a region code.
Approximate location
Country and region are usually right. The city is often the provider's hub, far from your home.
Address block
The range your address belongs to, and the regional registry that recorded it.
Why the name may not match your bill
The lookup names the company that registered the addresses, and that can differ from the brand you pay. Spectrum customers usually see Charter Communications, the company behind the Spectrum brand. A provider that rents another company's network can show that company's name. A provider that merged or renamed itself can keep its old name in the records for years. And on a VPN, a proxy or a cloud desktop, the name belongs to the company that runs that server.
Why your provider matters to the sites you visit
Sites weigh a visit partly by the network it comes from. Home and mobile providers serve people, so their addresses get the benefit of the doubt. Datacenter networks mostly serve machines, so traffic from them meets more captchas and checks. Mobile carriers and many home providers put a crowd of customers behind one shared address, so one subscriber's abuse can follow everyone on it. If a site keeps challenging you, the network shown here is one of the first things to check.
What your provider can see
Your provider carries all of your traffic, so it sees which servers you connect to and when, and usually the names of the sites you visit. On sites that use HTTPS it cannot read the pages, messages or passwords you send. A VPN hides that view from your provider and hands it to the VPN company instead.
Questions people ask.
Your ISP, short for internet service provider, is the company that connects you to the internet. Yours is shown at the top of this page, read from the address your connection reached us from. On a VPN or a proxy, the name shown belongs to that service.
Open this page on the connection you want to check, and the provider is shown at the top. Your bill and your router's settings page name it too. On a phone, turn Wi-Fi off to see your mobile carrier, or on to see your home provider.
Address blocks are registered to companies, and that company can be your provider's parent, the network it rents, or an older name. Spectrum, for example, shows as Charter Communications. If the name belongs to a VPN or hosting company, a VPN, a proxy or a work network is carrying your traffic.
Yes, every site you visit can. Your address travels with every request, and the provider behind an address is public record. That is how this page knows it, and it is one of the first things a fraud check looks at.
It sees which servers you connect to and usually the names of the sites, because it carries the traffic. On HTTPS sites it cannot read the content: pages, messages, passwords and card numbers stay encrypted. A VPN moves that view from your provider to the VPN company.
Most home connections get an address that changes now and then, often when the router restarts or after a set time. Mobile connections change addresses often. Business plans can pay for a static address that stays the same. The provider shown usually stays the same either way, because the new address comes from the same network.
Location from an address is an estimate, and providers often register their blocks to a central hub. Country and region are usually right; the city often is not. Your provider knows your real address from your contract and does not publish it.
From the outside you cannot: the VPN replaces your address, so every site, this one included, sees the VPN's provider. Disconnect the VPN and reload this page to see your own.
