Summary
Colba Net
isp legacy
COLBANET — Colba Net Inc., an independent internet service provider based on
rue du Collège in Montreal, Quebec. It announces roughly 12.5k IPv4 addresses.
What it's used for
- Retail internet access in the Montreal area. Reverse DNS across the space is full of subscriber-style names such as
5-80-252-216-dsl.colba.netand10-96-180-199-dsl.colba.net— DSL lines sold to homes and small businesses. - Part of the block carries
enter-net.comhostnames, a second brand riding the same network.
Notable
- Eyeball address space, not hosting or transit: the
-dslnaming convention on customer addresses is the tell. - A regional Canadian independent, not one of the national incumbents — the routed footprint is a handful of prefixes rather than the thousands a large cable or telco operator carries.
Interesting
- Colba Net has held this ASN since 1996, making it one of the longer-lived independent ISPs in Quebec.
