Summary
IP Synergies
transit isp france
The AS handle IPSYN-AS is held by Association IP Synergies.
What it's used for
- The space carries transit and gateway infrastructure, evidenced by reverse DNS entries such as
bcast-transit-ovh.routers.ipsyn.netandgw-ild.ipsyn.net. - The AS announces 512 IPv4 addresses and 1 IPv6 prefix, with 44 observed neighbours. This ratio of limited address space to a high number of peering partners indicates a transit or upstream provider role rather than a large access network.
Notable
- The registrant
IPsyn Admins; Association IP Synergiesaligns directly with the AS holder name. - The address inventory consists of a single IPv4 prefix,
193.109.142.0/23, and one IPv6 prefix,2001:67c:6cc::/48, representing a compact and focused routing footprint.

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 1,852 prefixes, as published 2026-10-27. 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.
