ISP (Internet Service Provider) and IP Address

What is ISP?

ISP (Internet Service Provider) is a company that provides internet connection. ISPs assign IP addresses to customers and route internet traffic.

ISP and IP Address Management

ISPs obtain IP address blocks from RIR (Regional Internet Registry) organizations and distribute them to customers. Each ISP manages its own IP address pool.

ISP Information and IP Query

When an IP address is queried, which ISP the IP address belongs to can be seen. This information is important for network analysis and security research.
