About this network

A small German nonprofit network association (F3NETZE, F3 Netze e.V.). It is not a commercial VPS provider despite some registry labels — it runs privacy and community internet infrastructure, and is best known for operating Tor exit relays.

What it's used for

• Hosting community/privacy infrastructure, most visibly Tor exit nodes in the well-known 185.220.100.0/24 range.

Notable

• Traffic from an IP here is typically Tor exit traffic, not a hosted customer service — the real source is an anonymous Tor user, so it is frequently seen in abuse and anonymised-traffic contexts.
• The network is tiny (a handful of prefixes), run by volunteers rather than a hosting business.

Interesting

• The 185.220.100.0/24 block is one of the more recognisable Tor exit ranges on the internet.
