AS13315 — HBSNET

AS13315 announces 3 IPv4 prefixes covering 12,544 addresses and 0 IPv6 prefixes.

About this network

The school holds the autonomous system; the university holds every one of its addresses.

What it's used for

• The network of a university business school. 12,544 addresses across three IPv4 prefixes, one observed BGP neighbour, and no IPv6 announced.

Notable

• The AS handle is HBSNET and the holder is the business school.
• All three blocks are registered to the parent university.
• The prefixes are 199.94.0.0/19, 199.94.32.0/20 and 199.94.48.0/24, with netnames 199-94-0-0-19, 199-94-32-0-20 and 199-94-48-0-24.

Interesting

• A faculty running its own autonomous system inside a university that holds the address space is an organisational boundary made visible in routing. The school wanted control of its own announcements; the university kept the registration. Both facts are true at once and only the pair of records shows it.
• The netnames restate the prefixes, so every one of them is derived rather than written. Where a European record from the same era carries a company, a date or a city, these carry the address a second time.
• Three graded blocks from one contiguous region are the record of space granted in stages, each new piece taking the next size that fit. They are announced separately because they were received separately, not because they go anywhere different.
