AS14200 — MARSHALLUNIV

AS14200 announces 4 IPv4 prefixes covering 18,944 addresses and 1 IPv6 prefixes.

About this network

One block is still registered for asynchronous dial-in, and the netname says so.

What it's used for

• A university campus network. 18,944 addresses across four IPv4 prefixes plus one IPv6 prefix, 2620:3::/48, with two observed BGP neighbours.

Notable

• 206.212.0.0/18 carries the netname MARSHALL and 199.217.0.0/21 carries MARSHALL-CBLK, both registered to Marshall University with a Marshall University Computing Services contact.
• Two /24s carry WVGC and WVGC-ASYNCH.
• Twelve addresses were queried for reverse DNS and none returned a name.

Interesting

• ASYNCH is asynchronous serial: a modem pool. A whole /24 was set aside so dial-in sessions could each be handed a routable address, which is how remote access worked before anyone thought to conserve addresses. The block is still announced and still labelled for a service that has no users left.
• The other WVGC block shares its prefix, so both came from the same state-level body rather than from the university directly. Universities in small states often act as the technical arm of a government network, and the registry keeps the distinction long after the org chart forgets it.
• CBLK on the second block reads as a class-based allocation label, another piece of vocabulary from before prefixes had lengths.
• A very low 2620 assignment puts the IPv6 request among the earliest from this registry, which fits an institution whose research network needed it before its campus did.
• Two neighbours, no reverse names, and four announcements: a network that publishes as little as it can.
