Summary
Pittsburg State University
education research business
Three spellings of one campus netname, and a single upstream for all of it.
What it's used for
- A university network. Four IPv4 prefixes and one IPv6
/42announced from the United States, with a single observed BGP neighbour.
Notable
- The netnames are
PSUNET-2,NETBLK-PSUNET-CandNETBLK-PSUNET: the same campus name with a numeric suffix, a type prefix and a letter suffix, and a type prefix alone. - Every block is registered to the university itself, with no carrier and no role desk in the registrant field.
- The announced space spans a
/19, a/22and two/24blocks from unrelated ranges, which is four separate assignments rather than one allocation. - Twelve addresses were queried for reverse DNS and none returned a name.
Interesting
- The three netname variants are a timeline. A counter, a letter and a bare name are the marks of three different assignment eras, each following whatever convention the registry used at the time, and nothing has been rewritten since.
- One upstream for ten thousand addresses and a large IPv6 allocation is the standard university shape: a single research-and-education network carries everything, and commercial transit is reached through it rather than directly.
- A campus this size holding all of its own space, with no carrier-registered block anywhere in the record, is less common in this range than the borrowed-space arrangement most holders show.

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 1,771 prefixes, as published 2026-10-15. 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.
