education university research legacy

The campus ASN of Mississippi State University, the land-grant research university at Starkville. The handle MSSTATE matches the institution and the reverse DNS confirms it directly.

What it's used for

A large public university network. RIS sees 5 announced IPv4 prefixes carrying 73,216 addresses, no IPv6 in the observed set, and one observed neighbour. The anchor is 130.18.0.0/16, a full legacy Class B, with a set of 192.208.x blocks announced alongside it.

The rDNS puts the use beyond doubt. Sampled addresses in the 192.208 space answer as ws5-128.208.ext.dynamic.msstate.edu and similar: dynamic marks pooled, dynamically assigned client addresses, ws reads as workstation, and the whole name lives under msstate.edu. That is campus end-user space, the addresses handed to laptops, lab machines and dorm connections, held in the university's own zone rather than an upstream's.

Notable

Sixty-odd thousand addresses is a big footprint for a campus, and it comes from the era when a research university could be given an entire /16 on request. It is a legacy artefact, not a measure of current need.

The single observed neighbour is characteristic of university networking in the US: campuses connect upward through a state or regional research-and-education network rather than peering broadly on their own, so from the outside they look like a stub hanging off one provider.

Interesting

Mississippi State runs a substantial high-performance computing operation, so some of that space backs research infrastructure rather than ordinary campus traffic.

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: 454 networks and 1,854 prefixes, as published 2026-11-06. 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.
