About ipneighbour.com

ipneighbour.com is a free network intelligence tool that provides detailed information about IP addresses and domain names using publicly available, authoritative data sources.

What we do

When you look up an IP address or domain, we query multiple authoritative and public data sources to assemble a comprehensive view of the resource, including:

  • DNS resolution (A, AAAA, MX, NS, CNAME, TXT records)
  • Reverse DNS (PTR records)
  • ASN and BGP routing context via Team Cymru
  • Registry and allocation data via RDAP
  • Approximate geolocation
  • HTTP/TLS probing for domains
  • Infrastructure and hosting insights

Data accuracy

We clearly label our data by confidence level:

  • Authoritative: Data from official registries (RDAP, DNS, Team Cymru ASN mapping)
  • Derived: Conclusions drawn from authoritative data (e.g., provider inference from AS name)
  • Best effort: Approximate data that may not be accurate (e.g., geolocation)

The "neighbour" concept

The name "ipneighbour" reflects our interest in network context — understanding not just a single IP or domain, but its place within the broader network infrastructure. This includes identifying the ASN, prefix, hosting provider, and other contextual relationships.

We deliberately avoid overpromising capabilities like "all domains on the same IP" unless we can source this data reliably and lawfully.
