About this network

CEBRIDGE is the autonomous system for Cebridge Connections, a rural telecommunications provider.

What it's used for

• The address space carries customer access traffic, evidenced by netnames referencing specific towns such as CALDWELL-CEBRIDGE-CONNECTIONS, GRAINGEVILLE-CEBRIDGE-CONNECTIONS, BIDWELL-CEBRIDGE-CONNECTIONS, and SHINNSTON-CEBRIDGE-CONNECTIONS.
• The AS announces 2560 IPv4 addresses across 7 prefixes with only 2 observed neighbours, a ratio that indicates an access or eyeball network rather than a transit provider.

Notable

• Registrants are consistent with the announcer, listing Cebridge Connections for most blocks, while 209.33.20.0/24 and 209.33.22.0/24 list local customer groups as registrants.
• The inventory includes a block registered to Optimum with the netname SUDDE-NETBLK-NCT, which does not align with the Cebridge branding seen in the other prefixes.
• The address inventory is composed of small /23 and /24 blocks, reflecting a site-by-site segmentation typical of a regional fiber or DSL provider.
