Autonomous system
AS57157 BI-AS
Unclassified RIPE
Summary
bi. SAS
business france small
The AS handle BI-AS is held by bi. SAS.
What it's used for
- The address space carries business infrastructure, evidenced by the reverse DNS record
mail.isd-sa.comand netnamesFR-INIFLUX-20130703,FR-INIFLUX-20090624, andFR-INIFLUX-20030512. - The network announces 1536 IPv4 addresses across 3 prefixes and 1 IPv6 prefix, while maintaining 40 observed neighbours. This ratio of limited address space against a high number of peering partners indicates a transit or interconnection role rather than a large-scale access network.
Notable
- All registrants for the announced prefixes are listed as
bi. SAS, which agrees with the AS holder. - The address inventory consists of three distinct IPv4 blocks and one IPv6 /32, all located in France.

Interconnection
Peering at a glance
Internet exchanges
No exchange port on file. Many exchanges publish no participant list, so this is not proof of absence.
Transit providers
8 upstream, 0 downstream and 9 adjacent networks observed; most-used upstreams first.
Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-11, 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: 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.
