What it's used for

• The space carries infrastructure for a theoretical physics research centre, with the sole announced prefix 38.64.135.0/24 registered under the netname COGENT-A by Cogent Communications, LLC.
• The AS announces 256 IPv4 addresses across 1 prefix and maintains 1 observed neighbour, a ratio consistent with a small, self-contained institutional network rather than a transit or access provider.
• Traffic from this AS represents the digital footprint of an independent research institution in Waterloo, Canada, supporting staff, researchers, and associated scientific projects.

Notable
