Summary

Colba Net

Canada · AI-generated

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.net and 10-96-180-199-dsl.colba.net — DSL lines sold to homes and small businesses.
  • Part of the block carries enter-net.com hostnames, a second brand riding the same network.

Notable

  • Eyeball address space, not hosting or transit: the -dsl naming 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.

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: 445 networks and 1,817 prefixes, as published 2026-10-27. 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.
