Vultr

What it is

Vultr's RFC 8805 geofeed, published under its parent company's domain, naming the country and city of every prefix.

What it answers

In the IP response this source feeds is_datacenter, hosting_provider, location_source, city. Every answer names the datasets it read in its sources block with the date each was synced, so the figure on this page and the one in an answer are the same figure.

curl https://spaw.co/api/v1/ip \
  -H "Authorization: Bearer $SPAW_KEY" \
  -H "Content-Type: application/json" \
  -d '{"ip": "203.0.113.9"}'

How to read this page

A source names a network or an operator, never a person. An address inside one of these ranges tells you what the connection is — a cloud instance, a VPN exit, a gateway, a listed host — and nothing about who is behind it.

This page is a reference about detection, not a mirror of the operator's list: it prints counts and dates, not addresses. The operator publishes the list itself, at the address above, and is the place to read it.
