Canada · AI-generated

cooperative telecom quebec residential

CSUR is the autonomous system for Coop de solidarite du Suroit-CSUR.

What it's used for

  • The address space carries residential and community internet services, evidenced by netnames CSUR and POINTEFORTURE registered to the cooperative.
  • The AS announces 3072 IPv4 addresses across 2 prefixes with only 1 observed neighbour, a ratio characteristic of an access network serving local subscribers rather than a transit provider.
  • Traffic from this AS consists of subscriber eyeballs for the cooperative's members in the Suroît region of Quebec, utilizing the multiservice model for local connectivity.

Notable

  • Registrants for both announced prefixes agree with the announcer, listing Coop de solidarite du Suroit-CSUR as the holder.
  • The address inventory is compact, consisting of a /21 and a /22 block, reflecting a focused local deployment rather than a large-scale national footprint.

Classification and threat

Unclassified Not in the curated lists. Most of the ~80,000 allocated ASNs are not.

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 1,773 prefixes, as published 2026-10-13. 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.
