About this network

A private Bucharest university announcing leased address space.

What it's used for

• Campus connectivity. 512 addresses in one /23 with two observed BGP neighbours and no IPv6 announced.

Notable

• The AS handle is RAU-AS Bdul. Expozitiei,Nr. 1B — the description field holds the university's street address rather than a description.
• The single prefix, 93.113.252.0/23, is registered to IPv4 Management SRL with the contact IP.RO - NOC, under the netname RO-IPV4-20071221. The university announces it; somebody else holds it.
• Two neighbours, so the routing is redundant even though the addresses are borrowed.

Interesting

• An institution that leases its address space and runs its own AS has made a specific trade. The AS number is permanent and free to keep; the addresses are rented and would have to be given back. What it buys is the ability to change the arrangement underneath without the campus noticing.
• A netname of the form RO-IPV4-<date> names the business rather than the user: the holder is a company whose product is IPv4 addresses. Blocks allocated in 2007, before the free pool ran out, are now inventory.
