AS6145 SYNAPSIS-NET - Synapsis.io
Hosting ARIN Network Services
Summary
Synapsis.io
enterprise legacy
SYNAPSIS-NET is operated by Synapsis.io, a small Canadian software-development company that runs its own BGP-speaking network out of the Toronto area.
What it's used for
- A handful of prefixes: two IPv4 /24s and a small set of IPv6 /48s, supporting the company's own infrastructure rather than a customer hosting business.
- The network peers at ONIX, the Ontario Internet Exchange in Toronto, and takes transit from a single upstream.
Notable
- ARIN registered this ASN to Synapsis.io in 2022. The low number is a reassignment of a recycled ASN, not a survivor of the early internet, and the card should not be read as implying any older pedigree.
- The IPv6-heavy prefix list relative to a very small IPv4 footprint is typical of a network built recently and from scratch.

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: 448 networks and 1,851 prefixes, as published 2026-11-04. 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.
