Summary

B7C GmbH

Germany · AI-generated

business it-security datacenter

The AS handle BLUE7-AS is held by B7C GmbH.

What it's used for

  • The address space carries business and IT security infrastructure, evidenced by the netname DE-B7C-20190225 and registrant B7C NOC; B7C GmbH.
  • The AS announces 1024 IPv4 addresses across 1 prefix and 1 IPv6 prefix, with only 1 observed neighbour, indicating a small, self-contained business network rather than a transit or large access provider.

Notable

  • The registrant B7C NOC; B7C GmbH aligns directly with the AS holder, confirming consistent ownership of the announced space.
  • B7C GmbH operates a regional data center and provides IT security, GDPR compliance, and emergency management services, positioning the AS as a specialized business infrastructure provider.
  • The inventory consists of a single /22 IPv4 block and a /29 IPv6 block, representing a compact and focused address estate typical of a niche service 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: 448 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.
