Summary

TBits.net

Germany · AI-generated

business it security germany

The AS handle TBITS-NET-AS is held by TBits.net GmbH.

What it's used for

  • The address space carries corporate infrastructure, evidenced by the registrant netnames DE-TBITSNET-20100611 and DE-TBITSNET-20180913 and the reverse DNS entry pB2FAE3FF.dip1.tnip.net.
  • The network announces 3072 IPv4 addresses across 2 prefixes and 1 IPv6 prefix, with only 2 observed neighbours, indicating a small, self-contained corporate estate rather than a transit or large access provider.
  • Traffic from this AS consists of internal corporate endpoints for TBits.net's IT security and data protection services, located in Alfdorf, Germany.

Notable

  • The registrants for both announced IPv4 prefixes are TBits.net GmbH, matching the AS holder.
  • The address inventory is compact, consisting of one /21 and one /22 block, consistent with a single-site or small multi-site corporate deployment.

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: 442 networks and 1,771 prefixes, as published 2026-10-15. 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.
