About this network

The AS handle THING5-NA is held by Thing5, LLC.

What it's used for

• The address space carries a mix of Cogent Communications infrastructure and Thing5's own Chicago operations, evidenced by the netnames COGENT-A and T5-CHICAGO.
• With 512 IPv4 addresses across 2 prefixes and only 3 observed neighbours, the low neighbour count relative to the address inventory suggests a small-scale access or business network rather than a transit provider.

Notable

• The registrants do not fully align with the announcer; while Thing5, LLC owns the 192.139.205.0/24 block, the 38.65.31.0/24 block is registered to Cogent Communications, LLC.
• The address inventory is small and fragmented, consisting of two distinct /24 blocks with no announced IPv6 prefixes.
