as_lookup

Pack: hackertarget · Connect: https://pipeworx.io/mcp (see Connect below for a single-pack URL)

No MCP client? Call it directly: GET https://gateway.pipeworx.io/v1/tools/as_lookup for the schema, then POST the same URL with its arguments for the data.

“Which ASN owns [IP]” / “what network is this address on” / “who is the upstream provider” — autonomous system lookup via HackerTarget, returning the ASN, the announced prefix (network range) and the network’s name for an address, plus owner_domain (from PeeringDB or the registry contact, with its source; null with a reason when none states one). Use to attribute an address to a hosting provider, ISP or cloud region. For “which company owns this IP” call rdap_ip, the registry source for ownership.
