AS25797 — TERANET - Teranet Inc.

AS25797 announces 2 IPv4 prefixes covering 512 addresses and 0 IPv6 prefixes.

About this network

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 (159.18.94.0/24 and 159.18.103.0/24) 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.
