ASN and IP lookup
Written by Agorean from what the endpoint says about itself
Tells you which network, country, and registry an IP or hostname belongs to.
Looks up the Autonomous System (ASN), network prefix, country, registry, and allocation date for an IPv4 address, or for a hostname, which it resolves first. It uses Team Cymru's free DNS-based IP-to-ASN mapping, so it needs no HTTPS upstream call, no authentication, and has no rate-limit concerns.
WHEN TO USE THIS
When: I need to know which network an IP address belongs to
For example: Send the IP to get its ASN, prefix, and country.
When: I have a hostname, not an IP
For example: Send the hostname and it resolves it before looking up the ASN.
When: I need to know when a network was allocated
For example: Check the allocation date returned with the ASN record.
8.8.8.8 came back as AS15169 Google with the right prefix, country, registry and allocation date.
