IP Lookup

Q: How do I know the IP Lookup output is good?

The skill verifies itself against its own quality checks: The interpretation (network ownership + type) leads; raw fields follow; City/coordinates are labeled approximate every time; The hosting/proxy flags are read when the question was VPN/datacenter-shaped; Hostnames were resolved and the resolved IP shown.

Look up IP addresses and your own public IP with zero API keys — geolocation, ISP/ASN, and hosting flags via ip-api.com and ipify through curl. Use when asked what's my public IP, where is this IP from, whose network is this address, or is this IP a VPN/datacenter. Produces the lookup with ISP, ASN, and location fields interpreted honestly (city-level accuracy caveats included), and the rerunnable command.

What to give it

▸The IP (or "mine") — v4 or v6; a hostname is fine (it gets resolved first — say so)

▸The purpose — log triage wants the ASN/hosting read; debugging wants "is my egress IP what I think"; abuse-report prep wants the network owner — the interpretation follows it

✅ The bar it holds itself to

Every skill in this library self-verifies — these are this skill's own quality checks, straight from its definition.

✓The interpretation (network ownership + type) leads; raw fields follow

✓City/coordinates are labeled approximate every time

✓The hosting/proxy flags are read when the question was VPN/datacenter-shaped

✓Hostnames were resolved and the resolved IP shown

✓The networks-not-people line appears

⚠️ What it refuses to do

Do not present city/coordinates as a location fix — it's an estimate of the ISP as often as the user

Do not assist with locating or unmasking individuals — networks and abuse contacts, not people

Do not bulk-loop a rate-limited free endpoint — for log volumes, dedupe first and note the limit

Do not answer "what's my IP" from memory or the environment — fetch it; NAT and VPNs make assumptions wrong

Do not conflate ISP and org — the `as`/`org` fields differ exactly when it's interesting (resellers, VPNs, corporate egress)
