FAQ
What is my ISP?
Your ISP (Internet Service Provider) is the company that provides your internet connection — for example Comcast, AT&T, Vodafone, or a local broadband provider. This page looks up the network that announces your current public IP and displays the registered provider name.
Why does a VPN show a different ISP?
A VPN routes your traffic through the VPN provider's network. The ISP shown here will be the VPN company or their upstream datacenter — not your home broadband provider. Disconnect the VPN and refresh to see your real ISP.
How accurate is ISP detection?
ISP names come from public IP geolocation and WHOIS databases. They are accurate for major residential and mobile carriers. Corporate networks, satellite links, and some hosting IPs may show a parent company or datacenter name instead of a retail brand.
What is the difference between ISP and organization?
The ISP field is the consumer-facing provider name. The organization field often shows the legal entity or network operator registered for the IP block — they may differ when a brand operates under a parent ASN.
Does mobile data show a different ISP?
Yes. On cellular, your ISP is your mobile carrier (for example T-Mobile, EE, Telstra). On Wi‑Fi at home, it is your broadband provider. Switch networks and refresh to compare.
How is this different from What Is My IP?
What Is My IP leads with your address and adds location and timezone. This page leads with your ISP name and adds organization, ASN, and location context for provider-focused questions.
Introduction
What Is My ISP identifies the Internet Service Provider associated with your current public IP address, displayed front and center with a one-click copy button. Below it, a details panel adds the registered organization, your public IP, approximate location, and ASN so you have the full network context in one view.
ISP name is a common question in support, compliance, and streaming troubleshooting — it tells you who operates the network you are on, whether that is home broadband, mobile data, office fiber, or a VPN exit. Looking it up should not require WHOIS commands — this page resolves it from your live connection.
What is an ISP?
An ISP (Internet Service Provider) is the company that sells you internet access and assigns your public IP address from their allocated IP blocks. ISPs register those blocks with regional registries and announce them on the internet via BGP routing.
| Connection type | Typical ISP shown |
|---|---|
| Home broadband | Comcast, BT, NTT, Telmex, etc. |
| Mobile data | Verizon, Vodafone, Airtel, etc. |
| VPN active | VPN provider or their datacenter host |
| Office / cloud | Corporate entity or cloud provider (AWS, Azure) |
The name shown here comes from the network that currently announces your public IP — refresh after changing networks or toggling a VPN.
Common use cases
- Streaming and geo-restriction debugging — confirm which provider and region your IP maps to.
- Support tickets — tell an ISP or SaaS vendor who provides your connection when they ask.
- VPN verification — check that your ISP changed to the VPN provider after connecting.
- Network audits — document which upstream provider a remote employee or kiosk is using.
Best practices
- ISP detection reflects your public IP right now — it updates when you switch Wi‑Fi, mobile data, or VPN servers.
- The location row is approximate (city or region level) and may reflect the ISP's hub, not your exact address.
- For the numeric network identifier behind your ISP, see what is my ASN; for the raw address, see what is my IP.
- To investigate any IP that is not your own, use IP address lookup.
