Identify the internet service provider, organization, ASN and approximate network location associated with an IP address.
An ISP lookup identifies the internet service provider and network information associated with a public IP address. This can help you understand which provider operates a network and where the IP address is approximately located.
Enter an IPv4 or IPv6 address above to check available information such as the ISP, organization, autonomous system number (ASN), country, region, city and timezone.
Depending on the IP address and available registration data, an ISP lookup may provide several types of network information.
An ASN, or Autonomous System Number, identifies an autonomous system that exchanges routing information with other networks on the internet. Internet service providers, hosting companies, cloud platforms and large organizations can operate autonomous systems.
ASN information is useful when investigating network ownership, routing, hosting infrastructure and the organization behind a public IP address.
No. An IP address generally does not provide a person's exact physical address through a normal public lookup. Geographic information shown by IP databases is approximate and may represent a city, region, datacenter, exchange point or another location associated with the network.
ISP lookup results should therefore be treated as network-level information rather than an exact representation of where a person is physically located.
An ISP, or Internet Service Provider, is a company or organization that provides internet connectivity to customers, businesses or other networks.
You can check public IPv4 or IPv6 addresses. Private addresses such as 192.168.1.1 are not publicly routable and normally cannot be mapped to a public ISP in the same way.
They overlap, but an ISP lookup focuses primarily on the network provider and related information, while a general IP lookup may provide additional geographic or technical details.
IP databases are based on network registration, routing and geographic datasets. Addresses can move between providers, organizations or datacenters, so results may not always represent the current physical location perfectly.
