AS6145 — SYNAPSIS-NET

Network type: hosting

AS6145 announces 2 IPv4 prefixes covering 512 addresses and 1 IPv6 prefixes.

About this network

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.
