Summary

zeroBS GmbH

Germany · AI-generated

security consulting ddos business

The AS handle ZEROBS is held by zeroBS GmbH.

What it's used for

  • The space carries corporate infrastructure for an IT security firm, evidenced by the netname NET-87-76-213-0-24 and registrant Private Customer.
  • The inventory consists of 256 IPv4 addresses and 1 IPv6 prefix, with only 1 observed neighbour, indicating a small, self-contained business network rather than a transit or access provider.

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 1,845 prefixes, as published 2026-10-31. 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.
