AS19446 3ZCANADA-01 - 3Z Canada
Unclassified ARIN
Summary
3Z Canada
business canada colocation
The AS handle 3ZCANADA-01 is held by 3Z Canada.
What it's used for
- The address space carries a mix of corporate and third-party infrastructure, with netnames including
3ZCANADA-01,CAC-BLOCK5,CAC-BLOCK10,NETUTILS, andIMS-CA. - The AS announces 4096 IPv4 addresses across 10 prefixes and 1 IPv6 prefix, while maintaining only 3 observed neighbours, a ratio that suggests a business or internal corporate estate rather than a transit provider.
Notable
- Registrants vary significantly across the inventory, including 3Z Canada, Colocation America Corporation, Internet Utilities NA LLC, and Inquiry Management Systems, indicating the space is composed of multiple distinct blocks.
- The address inventory is fragmented into ten separate IPv4 prefixes, with the largest being a /22 and the rest ranging from /23 to /24, reflecting a non-contiguous allocation.

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 2026-11-05, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

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: 453 networks and 1,854 prefixes, as published 2026-11-06. 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.
