Identify Internet Service Providers (ISPs) associated with any IP address, including network details and location info.
What is an ISP Lookup?
An ISP Lookup tool helps you identify and understand details about Internet Service Providers associated with any IP address. Just as every house needs a postal service to deliver mail, every internet connection requires an ISP to provide access to the web. Our ISP Lookup tool instantly reveals which company provides internet service for any IP address, along with detailed network information and location data.
Why use an ISP Lookup?
Whether you're troubleshooting network issues, investigating suspicious activity, or simply curious about network infrastructure, our ISP Checker provides valuable insights into the companies powering internet connections. Network administrators use ISP Lookup to verify legitimate service providers, while security researchers utilize it to track potential threats. Businesses can also use this data to understand their visitors' connection types and optimize their services accordingly.
Understanding ISP Lookup Results
When you use our ISP Lookup tool, you'll receive comprehensive information about the Internet Service Provider, including the organization name, network details, and geographic location. The results also show whether the connection is residential, business, or datacenter-based, along with autonomous system numbers (ASN) and network ranges. This information helps you understand not just who provides the service, but how the network is structured and managed.

Can ISP Lookup show historical ISP information?
Our ISP Checker shows current ISP information only, as IP addresses can be reassigned between different ISPs over time.
Will ISP Lookup work if someone is using a VPN?
No, our ISP Checker will show the VPN provider as the ISP, not the person's actual internet service provider.
Is using ISP Lookup legal?
Yes, ISP Lookup is completely legal as it only accesses publicly available information that ISPs and regional internet registries publish for transparency and network management purposes.
How often is the ISP database updated?
Our ISP Lookup tool uses real-time data from regional internet registries and is automatically updated as ISPs register changes to their networks.
