Unclassified ARIN
Summary
Teranet Inc.
business government canada registry
The AS handle TERANET is held by Teranet Inc., a Canadian company that operates statutory registry services, including Ontario's electronic land registration system.
What it's used for
- The address space is registered to Zayo Bandwidth with netnames
ZAYO-CAN-20, indicating the IP blocks are leased or provisioned by a bandwidth provider rather than being native Teranet infrastructure. - The AS announces 512 IPv4 addresses across 2 prefixes (
159.18.94.0/24and159.18.103.0/24) and maintains 2 observed neighbours, a ratio consistent with a small-scale business or government entity using leased transit or connectivity rather than operating a large access network.
Notable
- The registrants for both announced prefixes are Zayo Bandwidth, which differs from the AS holder Teranet Inc., suggesting the address space is leased from Zayo for Teranet's use.
- Teranet Inc. is a private corporation providing land registry services to the Ontario government, not a telecommunications carrier, which explains the small, leased address inventory.
- The inventory consists of two contiguous /24 blocks, a typical allocation for a single corporate site or service endpoint.

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 2026-10-19, 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: 442 networks and 1,783 prefixes, as published 2026-10-20. 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.
