6 tools

• ip_lookup

  Look up geolocation, ISP and network info for any IPv4/IPv6 address or hostname, or an array of them for batch lookup. Returns ip, city, region, country, coordinates, ASN/ISP, timezone and continent (full name, e.g. North America); when a domain is queried, an extra `domain`…

• ip_resolved

  Resolve a domain to all its A and AAAA records (deduplicated, up to 6) and return geolocation for each address. Returns an array of { ip, protocol, domain, city, region, country, coordinates, ASN/ISP, ... }. For a bare IP, returns a single-element array.

• ip_self

  Get geolocation and network info about the caller's own public IP, plus the protocol stack (IPv4/IPv6) of the current connection. On dual-stack machines the stack is chosen by the client and may differ from `curl ip.ls`, which picks a random stack; use curl -4/-6 locally to get…
