How to Check and Identify Your Internet Service Provider

Having a reliable internet connection is crucial in the modern digital world. Your internet service provider (ISP) plays a key role in determining the quality of your internet access. This article provides a step-by-step guide on how to check and identify your ISP.

What is an Internet Service Provider (ISP)?

An ISP is a company that provides users and businesses access to the internet[1]. Some examples of major ISPs in the US include Comcast Xfinity, Spectrum, AT&T, Verizon Fios, CenturyLink, Cox, Optimum, Frontier, Mediacom, Suddenlink, and Windstream.

ISPs make internet access possible by operating network infrastructures and providing internet plans for consumers and businesses. They offer various types of internet connections, including:

  • DSL (Digital Subscriber Line) – Uses telephone lines to provide internet access with download speeds up to 100Mbps[2].
  • Cable – Uses the same coaxial cables that deliver cable TV services with speeds up to 1000Mbps.
  • Fiber – Offers the fastest speeds using fiber optic cables to deliver speeds above 1000Mbps.
  • Satellite – For rural or remote areas unreached by cables. Speeds vary between 12Mbps to 100Mbps.
  • Fixed Wireless – Uses radio towers to deliver internet with speeds around 30Mbps to 100Mbps.

Why You Should Identify Your ISP

There are several reasons why you need to identify your ISP:

  • Check Internet Speeds – You can verify if you are getting the internet speeds you are paying for through your ISP.
  • Troubleshoot Connection Issues – Identifying your ISP allows you to easily contact them for any connection problems.
  • Shop for Better Rates – You can compare plans and prices if you want to switch to another ISP serving your area.
  • Avoid Scams – Scammers often pretend to be from an ISP to get your personal information. Knowing your actual ISP protects you.

How to Identify Your Internet Service Provider

There are several easy ways to find out your ISP:

1. Check Your Bill or Bank Statement

Your ISP name will be clearly listed on your internet bill or bank statement for automatic payments. This is the simplest way to confirm your ISP if you have recently signed up for an internet plan.

2. Look Up Using Your IP Address

Your public IP address can be used to identify your ISP[3]:

  • Go to the website and enter your IP address.
  • Alternatively, simply search “What is my IP address” on Google to find your public IP address.
  • Enter that IP address on sites like or to see your ISP details.

3. Check Network Settings on Your Device

You can also identify your ISP from the network settings menu on your computer, smartphone and other devices connected to your home internet:

  • Windows – Go to Network Settings > Ethernet/Wifi > Network Properties
  • Mac – Apple Menu > System Preferences > Network > Advanced
  • iPhone – Settings > WiFi > The “i” icon next to network name
  • Android – Settings > Connections > WiFi > The “i” icon next to network name

Your ISP name will be displayed next to “Service Provider” in the details shown.

4. Identify Using Your Modem/Router

The model number and name listed on your modem or router often indicates the ISP. For example, an Xfinity router from Comcast or AT&T WiFi router.

You can also log into your modem/router admin interface by entering the default gateway IP address on your web browser. The ISP name is typically mentioned on the login page or home screen.

5. Check ISP Availability By Your Address

You can enter your zip code or full address on sites like and Allconnect to view all the ISPs providing service around your location. Identify the ISP you have signed up with to confirm the name.

Tips for Choosing Your Internet Service Provider

  • Compare internet plans and pricing from all ISPs in your area before selecting one. Avoid locked annual contracts if possible.
  • Confirm the type of internet connection to understand speed capabilities. Prioritize fiber, cable or fixed wireless over outdated DSL.
  • Check ISP rating on third-party sites like Consumer Reports and J.D. Power for customer satisfaction feedback.
  • Contact the ISP before signing up to inquire about any extra fees, data caps, and total monthly charges.

Reliable and fast internet access is vital for consumers and businesses today. Identifying your current ISP ensures you have all the details to make informed decisions about your internet service.
