Summary
South Plains College
education business infrastructure
Both contacts are departments spelled out in full, and both blocks are numbered by hand.
What it's used for
- A college's network. Two IPv4 prefixes announced from the United States, no IPv6, eight thousand one hundred and ninety-two addresses, through one observed BGP neighbour.
Notable
- The two netnames are the college's initials, three letters abbreviating the word block, and a counter: one and two.
- The blocks are the same size and sit on unrelated ranges, so the counter records the order they were acquired in and nothing else.
- Both list the same two extra contacts, each a department written out at full length: an operations centre and a group named for the act of reporting abuse.
- The AS handle is the college's three initials alone, with nothing appended.
- Six addresses were queried for reverse DNS and none returned a name.
- The country field is missing the small word between the two halves of the country's name.
Interesting
- A contact named for reporting rather than for handling is a careful piece of wording. It describes what the address is for, not what will happen next, which is more honest than most abuse contacts manage.
- Two equal blocks numbered in order is the clearest netname scheme in this range: it says how many there are, which came first, and nothing anybody has to decode.
- Eight thousand addresses on one upstream is a campus that treats its connection as a single service. The blocks are doubled; the path out is not.

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 1,783 prefixes, as published 2026-10-20. 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.
