Tools as reported by the server

• 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` field echoes it. Data so
• 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 the other stack, or —
• headers
  Return all HTTP request headers as seen by the IP.LS server (including X-Real-IP / X-Forwarded-For injected by the frontend proxy). Useful for debugging proxies and client identity.
• ua
  Return the User-Agent string of the current HTTP client.
• ip_summary
  Summarize a large batch of IPs into distributions by country, continent, ASN/operator and network prefix, each bucket with a sample of addresses. Use instead of ip_lookup once the input is in the hundreds or thousands — ip_lookup returns every row, which no context window holds. Up to 5000 addresses
