Summary
3xK Tech GmbH
proxy hosting
The primary network of 3xK Tech GmbH, a German hosting provider whose address space is widely resold and used as proxy egress by third-party proxy services (e.g. PlainProxies, SX.ORG).
What it's used for
- Datacenter hosting whose IPs are heavily used as commercial proxy exits rather than as ordinary server hosting.
Notable
- An IP here identifies 3xK Tech as the host, not the tenant — much of the space serves as proxy egress, so an IP is typically a shared proxy exit rather than a single end user's real address. The network has been repeatedly flagged for proxy/abuse and appears on VPN/proxy detection lists.
Interesting
- 3xK runs a second Autonomous System — see sibling AS198571.

Spamhaus DROP ("Don't Route Or Peer") lists space and networks run by, or hijacked for, spam and cybercrime operations: 442 networks and 1,773 prefixes, as published 2026-10-13. A short, high-confidence list, so a match is worth taking seriously, and absence from it says little on its own.
