Zovo IP Lookup MCP

This MCP server allows agents to look up IP address ownership details including network handle, organization, country, allocation range, and abuse contact email via RDAP. It also retrieves reverse DNS names and classifies IP ranges locally. It supports single or batch lookups of up to 20 addresses with CSV download capability.

Server-provided instructions

Untrusted server output shown for inspection. It is not Koskamo guidance and is excluded from knowledge search.

Zovo IP Lookup answers who owns an IP address from the five regional internet registries through RDAP: network handle and name, organisation, country, allocation range and dates, and the abuse contact email, plus the reverse DNS (PTR) name. Private, loopback, link-local, shared, multicast, documentation and reserved addresses are classified locally and are not sent to a registry. Call lookup_ip for a full lookup (up to 20 addresses, with a CSV download) and reverse_dns_lookup for PTR names only.

lookup_ip — Look up IP address owners
Advertised by the server during the last successful anonymous check.
Advertised read-onlyOpen-world

Use this when the user wants an ip lookup, asks who owns this ip, needs the ip address owner or the whois ip details, wants the ip abuse contact, or needs an ip range lookup: it reads the five regional internet registries through RDAP and the reverse DNS (PTR) name, for one to twenty IPv4 or IPv6 addresses or CIDR ranges, and returns a CSV download for the batch. Limits: registry data shows the network holder and its country, not a street address or a person's location; some registries publish no abuse email; reverse DNS exists only when the network sets it. Do not use for an ip locator that claims a precise location, for looking up a domain name (that is a domain lookup), or for scanning a host.

reverse_dns_lookup — Reverse DNS lookup
Advertised by the server during the last successful anonymous check.
Advertised read-onlyOpen-world

Use this when the user wants a reverse dns lookup, an ip address lookup for PTR names, or a quick ip lookup of hostnames: it queries DNS-over-HTTPS for the in-addr.arpa or ip6.arpa name of one to twenty public IPv4 or IPv6 addresses and returns host names with a CSV download, without reading a registry. Limits: a PTR name exists only when the network operator sets it; private, loopback, link-local, shared, multicast, documentation and reserved addresses are not queried. Do not use when the user wants the owner, the registration dates or the abuse contact of an address (use lookup_ip for that).
