Summary

Marshall University

United States · AI-generated

education research infrastructure

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.

Classification and threat

Unclassified Not in the curated lists. Most of the ~80,000 allocated ASNs are not.

Spamhaus DROP

Not on ASN-DROP The network as a whole is not listed.

No DROP prefixes None of its announced space is on the DROP prefix list.

Spamhaus DROP ("Don't Route Or Peer") lists space and networks run by, or hijacked for, spam and cybercrime operations: 442 networks and 1,784 prefixes, as published 2026-10-19. A short, high-confidence list, so a match is worth taking seriously, and absence from it says little on its own.

FBI IC3

No IC3 indicators Nothing from the FBI IC3 feed.

IC3 threat data is alpha. Absence of an indicator is not evidence of good behaviour, only of absence from this one feed.
