lookup_ipLABSCO SUMMARY
Whose network is this address on?
It answers the question that normally costs a browser tab in the middle of an investigation — country, ASN, owner — and can answer it about the machine you are on without you finding your own address first.
What it is
A GeoIP and ASN lookup against the IPRout API. Give it an IPv4 or IPv6 address and it returns location and network ownership; ask without one and it resolves the caller's own address.
What you get
- GeoIP and ASN detail for any IPv4 or IPv6 address
- The same for the caller's own address, with nothing to pass
- Country, ASN and owning organization in a single response
Requirements
Node.js 18 or higher and an IPRout API key, which travels as an X-API-Key header. The API base URL is configurable and defaults to https://api.iprout.com.
Setup effort
Build from source — git clone https://github.com/IProut2026/mcp-server
USE CASES
01
Checking where a suspicious address comes from
One lookup gives the country and the network behind it, which is usually enough to decide whether a login or a request deserves more attention.
02
Finding out which network you are on
No argument needed — it reports the address IPRout sees you from, which is the quickest way to confirm a VPN or a proxy is doing what you think.
03
Attributing traffic in a log to its owner
Addresses resolve to the organization that owns the ASN, so a list of hits becomes a list of providers and companies.
