AS14263 SD-NET - South Dakota State Government
Unclassified ARIN
Summary
South Dakota State Government
government education infrastructure
A state network that also routes a city and a university, with one netname that records a system already described as old.
What it's used for
- A state government's network. 29,184 addresses across 22 IPv4 prefixes plus one IPv6 prefix,
2607:f578::/32, with ten observed BGP neighbours.
Notable
- Most blocks carry
DDNNET-BLK-1orDDNNET-BLK-2, registered toSouth Dakota State Government. 206.176.32.0/22carriesSDNET-CITY-SF-1, registered toCity of Sioux Falls.- Two blocks are registered to
Black Hills State University, one asDDN-BHSU-1and the other asSDNET-BHSU-OLD-SDLN. - Eighteen addresses were queried for reverse DNS and none returned a name.
- The prefixes descend from a
/18through/21s,/22s and/23s to eight separate/24s.
Interesting
- A netname containing the word old is a note to a future administrator. Whatever the acronym at the end stood for, somebody wanted the record to say this block predates the current arrangement, and the registry is the only place that comment could live.
- State networks in sparsely populated places tend to become everybody's network. A city hall and a university sitting inside the same announced space is cheaper than each buying transit alone, and the registry is where the shared arrangement becomes visible.
- Ten neighbours is unusually well connected for this size. Carrying other institutions means carrying their peering requirements too.
- Eight single
/24s at the bottom of the plan are almost certainly individual agencies or remote sites, each small enough that anything larger would be waste.

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: 451 networks and 1,853 prefixes, as published 2026-11-04. 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.
