About this network
SD-STATE-UNIVERSITY is South Dakota State University, the state's largest public university, based in Brookings. It is a single-campus higher-education network.
What it's used for
Campus networking for students, faculty, administration and research computing. The AS announces exactly one prefix — 137.216.0.0/16, 65,536 addresses, no IPv6 — registered to SDSTATE (org: South Dakota State University). One contiguous legacy /16, announced whole, held by the institution that uses it: there is no ambiguity to resolve here about who operates the space or what it carries.
Notable
Two observed BGP neighbours. For a network with 65k addresses that is a small number, and it is the useful signal: a university edge takes transit from one or two providers (regionally, that usually means a state research-and-education network plus a commercial upstream) and does not peer widely. A wholesale carrier moving comparable address volume would show neighbours in the hundreds. So despite the size, this is an eyeball-and-servers campus, not infrastructure.
The absence of any announced IPv6 is worth flagging for an R&E network of this size — universities are usually among the earlier adopters, and RIS sees none here.
Interesting
Easy to confuse with AS11602, the South Dakota School of Mines & Technology in Rapid City. Two separate South Dakota institutions, two separate ASes, five numbers apart. The similarity of the names is a good reminder that an AS handle identifies a legal entity, not a category.
