Germany · AI-generated

cloud hosting dedicated

An older Autonomous System of plusserver, the German cloud and hosting provider. This legacy block is now consolidated under plusserver's primary ASN.

What it's used for

  • German-based hosting, dedicated servers, and cloud infrastructure.

Notable

  • An IP here identifies plusserver as the host, not the operator of whatever runs on it.
  • See the primary plusserver ASN AS61157 (AS61157) and sibling AS6659 (AS6659).

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-16, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

Classification and threat

Hosting Datacenter or cloud provider. Addresses are servers, not people.

Spamhaus DROP

Not on ASN-DROP The network as a whole is not listed.

No DROP prefixes None of its announced space is on the DROP prefix list.

Spamhaus DROP ("Don't Route Or Peer") lists space and networks run by, or hijacked for, spam and cybercrime operations: 442 networks and 1,783 prefixes, as published 2026-10-17. A short, high-confidence list, so a match is worth taking seriously, and absence from it says little on its own.

FBI IC3

No IC3 indicators Nothing from the FBI IC3 feed.

IC3 threat data is alpha. Absence of an indicator is not evidence of good behaviour, only of absence from this one feed.
