Summary

Tucows

Canada · AI-generated

business hosting domain

TUCOWS-3 is the autonomous system for Tucows.com Co., a Canadian domain name registrar and web services provider.

What it's used for

  • The address space carries infrastructure for Tucows and its subsidiaries, with netnames TUCOWS-BLK2 and TF-CNCO01-OPENSTACK-BLK01 indicating internal corporate and cloud infrastructure.
  • The AS announces 16,896 IPv4 addresses across 18 prefixes and 2 IPv6 prefixes, with only 1 observed neighbour, implying a self-contained corporate network rather than a transit or access provider.

Notable

  • Registrants include both Tucows.com Co. and Ting Fiber Inc., with Ting Fiber holding prefixes like 64.98.152.0/21 and 64.98.136.0/22, suggesting a corporate relationship or acquisition.
  • The inventory is finely subdivided into 18 IPv4 prefixes, consistent with an internal corporate estate segmented by function or site.

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 1,784 prefixes, as published 2026-10-19. 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.
