Summary

BIT-SERV

Germany · AI-generated

business corporate it-services

BIT-SERV is operated by Biesterfeld SE.

What it's used for

  • The address space carries internal corporate IT infrastructure, evidenced by netnames DE-BIT-SERV-20150227 and BIT-SERV-NET and reverse DNS entries like bit-000.185.89.229.bit-serv.de.
  • The AS announces 1536 IPv4 addresses across 2 prefixes and 1 IPv6 prefix, with only 2 observed neighbours, indicating a small internal corporate estate rather than a transit or access network.
  • Traffic consists of office workers and internal IT services for Biesterfeld SE's group headquarters and locations in Germany and abroad.

Notable

  • Registrants BIT-SERV Contact and Biesterfeld SE align with the announcer, confirming the space belongs to the same organisation.
  • The address inventory is finely subdivided into two distinct IPv4 blocks and one IPv6 prefix, consistent with site-by-site segmentation for a corporate IT provider.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-31, 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 1,843 prefixes, as published 2026-11-01. 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.
