About this network

The campus network of Florida Atlantic University, headquartered in Boca Raton with campuses along Florida's southeast coast.

What it's used for

• Campus networking for teaching, research and student access. The reverse DNS splits into two patterns under fau.edu: net143n255 style names for statically addressed segments and dhcp111n254 for the pools that hand addresses out dynamically.

Notable

• 28 IPv4 prefixes, all of them slices of a single 131.91.0.0/16 registered as FAU. The university holds one legacy class B and announces it in 28 pieces rather than as one route.
• Only two observed BGP neighbours despite that fragmentation. The deaggregation is not about steering traffic between many upstreams; it is internal structure made visible in BGP.
• No IPv6 announced.

Interesting

• FAU operates across multiple campuses spread over a hundred miles of coastline, from Jupiter down to Fort Lauderdale and Dania Beach. Carving a class B into 28 announced pieces is what a geographically dispersed institution ends up doing when it has one address block and many separate sites to fit into it.
