About this network

CRCSSD is the autonomous system for Calgary Catholic School District.

What it's used for

• The address space carries internal network infrastructure for a large school board, with netnames CRCSSDN and ALBERTA-1024 registered to the district and the Government of Alberta respectively.
• The AS announces 768 IPv4 addresses across 2 prefixes and maintains 1 observed neighbour, a ratio consistent with a single-site or small multi-site internal network rather than a transit or access provider.
• Traffic from this AS consists of office workers, students, and staff accessing web services, educational platforms, and internal administrative systems across the district's 118 schools.

Notable

• Registrants align with the announcer, with Calgary Catholic School District holding the primary /23 block and Government of Alberta holding the secondary /24 block.
• The address inventory is small and finely subdivided, reflecting an internal corporate estate segmented by site or function rather than a public-facing access network.
