01 / Domains
Domain intelligence
DNS records, nameservers, resolved IP addresses, server observations, reachability and historical changes as our probe network revisits the domain.
Building a public map of Internet infrastructure
Mapping the Internet,
one host at a time.
HostProbe is building a searchable catalogue of the world's domains, the IP addresses connected to them and the DNS servers that keep them reachable.
Search is being connected to the live catalogue.

The catalogue
Domains, addresses and DNS — connected.
We are not building another single-domain lookup box. HostProbe connects the pieces so you can move from a domain to its nameservers, addresses and network infrastructure — and back again.
02 / IP addresses
Where hosts actually live
See which domains point to an address, the network behind it, observed services and whether it is reachable from different HostProbe locations.
03 / DNS servers
The infrastructure behind DNS
Catalogue nameservers, the domains that depend on them, their addresses and availability, and the relationships that connect DNS infrastructure together.
Distributed probing
A host can be up here and unreachable somewhere else.
HostProbe uses multiple probe locations to observe reachability and infrastructure from different parts of the network. The goal is to show not just what a DNS record says, but what can actually be reached.

A growing, crawlable map of the Internet.
Public domain, IP and DNS pages will be permanent, linkable and readable by both people and search engines. As HostProbe discovers and analyzes more infrastructure, the catalogue grows with it.
