Summary

B2 Network

France · AI-generated

business france small

The AS handle NLN-AS is held by B2 Network SARL.

What it's used for

  • The space carries a single IPv4 block with netname FR-NOLIMITNETWORK-20130709 and registrant B2 Network SARL; B2Network DBM.
  • The AS announces 1024 IPv4 addresses and 1 IPv6 prefix, with 2 observed neighbours, indicating a small-scale business or internal network rather than a transit or large access provider.

Notable

  • The registrant B2 Network SARL matches the registry holder and the AS name NLN-AS in the CAIDA as2org data.
  • The address inventory consists of one contiguous /22 block and one /31 IPv6 prefix, representing a compact and simple allocation.

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: 432 networks and 1,768 prefixes, as published 2026-10-12. 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.
