AS13476 announces 17 IPv4 prefixes covering 80,640 addresses and 1 IPv6 prefixes.

About this network

One university announces another university's address blocks, and the netnames read like a directory of departments.

What it's used for

• A university's network. 80,640 addresses across seventeen IPv4 prefixes, the IPv6 block 2605:3640::/32, and two observed BGP neighbours.

Notable

• 153.90.0.0/16 is netname MSU, registered to the university with two technology-department contacts.
• Seven prefixes in 207.196 are netname NMP-BLK1, registered to a different university entirely.
• Smaller blocks are netnames MONTANANET, MONTANACOE, MONTANALIB and NMC, the last registered to a branch campus.
• Sampled names are gateway191.254.msu.montana.edu and c104-01-244461.gfcmsu.edu.

Interesting

• Announcing another institution's space is how a statewide education network works. One member runs the connection to the outside world and carries everyone else's routes, so the registry shows several universities and the routing table shows one.
• That gateway name splits the address across a word and a label boundary: the third octet is glued to gateway and the fourth stands alone. Every provider invents its own way of turning an address into a name, and this one turns it into two.
• The department netnames are a snapshot of what mattered when the blocks were requested. A separate /24 for the library and another for engineering is how address space was handed out when a /24 per building was a reasonable thing to ask for.
