Summary
Vaxxine Computer Systems Inc.
isp legacy
VAXXINE is Vaxxine Computer Systems Inc., a small independent internet provider based in St. Catharines, Ontario, serving the Niagara region of Canada. ARIN records the organisation at 80 Grantham South, St. Catharines.
What it's used for
Consumer and small-business internet access. The AS announces just two IPv4 prefixes — 192.161.96.0/19 and 209.159.176.0/20, about 12,288 addresses in total — and no IPv6. Reverse DNS on the second block resolves to names like ppp5.dsl.ontario.net and ppp1021.dsl.ontario.net: PPP session numbers on a DSL access concentrator, which is the signature of a subscriber access pool rather than a server estate. Both prefixes are registered to Vaxxine's own ARIN handles (VAXXINE-COM-2, and a block explicitly named for dynamic DSL in Ontario), so the space is first-party rather than leased in, and the network is a real operator rather than a shell announcing other people's address space.
Notable
Only two observed BGP neighbours. That is an eyeball network buying transit from a couple of upstreams, not a carrier — a wholesale transit AS of comparable size would peer with hundreds of others.
Interesting
The rDNS zone dsl.ontario.net is a nicely generic piece of naming for a network whose actual footprint is one corner of the province.

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.
Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-14, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

Classification and threat
Residential Fixed-line consumer ISP. Addresses here are homes.
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 1,772 prefixes, as published 2026-10-15. 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.
