Summary

Publicompserver

Germany · AI-generated

business germany small

The AS handle PUBLICOMPSERVER is held by Ingo Klein.

What it's used for

  • The address space carries server infrastructure, indicated by the netnames PUBLICOMPSERVER-NET and ORG-IKPS1-RIPE and the reverse DNS record 3.nbg.publicompserver.de.
  • The network announces 1280 IPv4 addresses across 2 prefixes and 1 IPv6 prefix, with only 1 observed neighbour, indicating a small, self-contained business network rather than a transit or access provider.
  • Traffic from this AS consists of web and API endpoints hosted by the operator, consistent with the "server" designation in the handle and domain name.

Notable

  • Registrants for both announced prefixes are listed as Ingo Klein, matching the AS holder.
  • The address inventory is small and subdivided into two distinct IPv4 blocks, one of which is a /22 and the other a /24, alongside a single /48 IPv6 block.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-30, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

Classification and threat

Unclassified Not in the curated lists. Most of the ~80,000 allocated ASNs are not.

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: 447 networks and 1,849 prefixes, as published 2026-10-30. 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.
