AS15199 — WWU

AS15199 announces 2 IPv4 prefixes covering 81,920 addresses and 1 IPv6 prefixes.

About this network

Eighty thousand addresses, and the residential network is named apart from the rest.

What it's used for

• A university network. Two IPv4 prefixes and one IPv6 prefix announced from the United States, with two observed BGP neighbours.

Notable

• The IPv4 space is a legacy /16 alongside a /18, together more than eighty thousand addresses.
• The two blocks carry different netnames: one marks the institution, the other marks the student residential network, so the registry separates dormitory traffic from campus traffic.
• Both registrant fields append an operations centre handle after a semicolon.
• The single IPv6 announcement is a /48, the smallest generally routed size, against eighty thousand IPv4 addresses.
• Six addresses were queried for reverse DNS and none returned a name.

Interesting

• Naming the residential network separately in the registry is genuinely useful, and rare. It tells an abuse handler which complaints concern students in halls and which concern university systems, before anyone has to ask.
• A /48 of IPv6 for a university with a /16 of IPv4 is a token allocation. It is enough for one site's worth of subnets, which suggests IPv6 here is a pilot rather than the campus network.
• Two upstreams for a university of this size usually means research and commodity traffic take different paths, and the registry gives no way to tell which is which.
