What Is My ISP?
Instantly identify your Internet Service Provider and detailed network information.
What Is an ISP?
An Internet Service Provider (ISP) is the company that provides you with access to the internet. They are the bridge between your personal devices (like your computer, smartphone, or smart TV) and the vast network of servers that make up the internet. Without an ISP, you wouldn't be able to send emails, stream videos, or browse websites like this one.
ISPs come in various forms, including:
- 1Cable/Fiber: Common for home internet (e.g., Comcast, AT&T, Verizon).
- 2Mobile/Cellular: Provides data to mobile phones (e.g., T-Mobile, Vodafone).
- 3Satellite: Used in remote areas (e.g., Starlink, HughesNet).
- 4DSL: Older technology using telephone lines.
Why Check Your ISP?
Knowing your ISP isn't just trivia—it's practical information that can help you solve real-world problems. Here’s why using our What Is My ISP tool is valuable:
Security Verification
Ensure your VPN or Proxy is working. If you see your real ISP name while connected to a VPN, your data might be leaking.
Network Troubleshooting
Pinpoint connection issues. Knowing if you are on the correct network (e.g., home vs. public Wi-Fi) is the first step in fixing lag.
Geolocation Check
See where websites think you are located. ISPs assign IPs based on regions, which affects available content.
How to Find Your ISP
Method 1: The Automatic Way (Recommended)
The easiest way is to use the tool at the top of this page. It automatically analyzes your connection and tells you:
- Your ISP Name
- Your Public IP Address
- Your Estimated Location
- The Organization managing your IP
Method 2: Manual Checks
If you are offline or need physical verification:
- Check your billing statement: Your monthly internet bill will clearly state your ISP's name.
- Look at your router: The device connecting you to the internet often has the ISP's logo branding.
- Speed Test sites: Most speed tests will also display your provider's name before starting the test.
Understanding ISP Data
When you check your ISP, you often see other technical terms. Here is a quick glossary:
- Public IP Address
- Your unique identifier on the internet. It's like your digital home address.
- Hostname
- A human-readable label assigned to your IP, often containing your ISP's name and location codes.
- ASN (Autonomous System Number)
- A unique number assigned to your ISP's network for routing traffic globally.
Frequently Asked Questions
Common questions about ISPs, IP addresses, and privacy.
What is my ISP and how do I check it?
Your Internet Service Provider (ISP) is the company providing your internet connection. You can instantly check it using our free tool above, which detects your public IP address and the associated ISP name.
Why does my ISP location show a different city?
ISP locations are based on where they register their IP blocks, not necessarily your physical house. It is common for the location to show a nearby major city or your ISP's regional hub rather than your exact street address.
Can I see my ISP just from my IP address?
Yes, every public IP address belongs to an Autonomous System (AS) managed by an ISP. Our tool performs a reverse lookup to identify the company owning your IP.
Does this tool show my Private or Public IP?
This tool detects your Public IP address. This is the external address visible to the internet. Your private IP (usually starting with 192.168.x.x) is only used inside your home network and is not visible here.
What does "Network Error" or "Connection Timed Out" mean?
A "Connection Timed Out" usually means your device cannot reach the ISP verification server. This can be caused by a firewall, poor signal strength, or a temporary outage with your local internet service provider.
Can my ISP see my browsing history?
Generally, yes. Unless you use encryption like HTTPS (which hides the specific page content) or a VPN (which hides everything), your ISP can see which domains you visit. Using a VPN is the best way to prevent ISP tracking.
How can I hide my ISP info and location?
To hide your ISP and location, you should use a Virtual Private Network (VPN). A VPN routes your traffic through a different server, masking your real IP and making it appear as if you are browsing from a different location and ISP.
