• The address space carries institutional traffic, evidenced by reverse DNS records pointing to brazosport.edu domains.
• The AS announces 4096 IPv4 addresses within a single /20 prefix (206.40.176.0/20) and maintains 5 observed neighbours, a ratio consistent with a small, self-contained educational network rather than a transit provider.

Notable
