Free online lookup of IPv4 and IPv6 network ranges for any ISP or organization
Enter a provider domain, a full URL, or any known IP address. The service resolves all IPv4 and IPv6 addresses, determines the ASN for each IP, and then shows the network ranges stored in the geoip_asn_blocks table.
If several ASNs are involved, each ASN is shown in a separate section so it is always clear which networks belong to which ASN.
Examples:
- beeline.ru
- https://beeline.ru/some/page
- 119.76.70.76
- 2001:4860:4860::8888
