## Tools (as reported by the server, not verified)

- `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
