Summary
Synapsecom Telecoms
hosting colo transit legacy
SYNAPSECOM-AS is the network of Synapsecom Telecoms S.A., an Athens-based Greek carrier and data-centre operator founded in 2007. It runs carrier-neutral colocation facilities in Athens (Ano Liosia) and Thessaloniki, and sells IP transit, leased lines, cloud and IaaS.
What it's used for
- Colocation, cloud and IP transit for Greek and regional customers. The AS peers widely and shows a large neighbour count for its size, which is what a transit and peering-heavy data-centre network looks like.
- Its own RIPE allocations (
78.108.32.0/20,46.227.56.0/21,185.51.132.0/22) carry the netnamesGR-SYNAPSECOM-20070613andGR-SYNAPSECOM-20110127.
Notable
- Not all the space is Synapsecom's own. Several announced /24s are registered to third parties and clearly labelled as such:
212.52.16.0/24,151.236.29.0/24and188.190.25.0/24all carry the description "EDIS Infrastructure in Greece" and are maintained by the Austrian hosting provider EDIS, and another /24 belongs to a Bulgarian data-services company. These are hosting tenants and transit customers, not brokered address space. - Consequently an address in this AS may belong to a customer's brand rather than Synapsecom, but the country is reliable: EDIS's blocks here are registered to Greece and sit in Synapsecom's Greek facilities.
- Little reverse DNS on Synapsecom's own allocations, which is normal for colocation space named by the tenant, not the landlord.

Classification and threat
Hosting Datacenter or cloud provider. Addresses are servers, not people.
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: 442 networks and 1,783 prefixes, as published 2026-10-17. 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.
