Network type: education

About this network

TJHSST-AS belongs to the Thomas Jefferson High School for Science and Technology in Alexandria, Virginia, a public magnet school in the Fairfax County school system. ARIN registered the ASN in November 1993.

What it's used for

• Carrying the school's own routed address space, used by its computer systems lab, student-run services and campus network rather than by a commercial provider.

Notable

• Institutional address space, not eyeball or hosting space. Traffic here is a single organisation's campus network.
• A secondary school holding its own AS number and a sizeable IPv4 block is genuinely unusual. Almost every other network in this range belongs to a university, a corporation or a government body.

Interesting

• The 1993 registration date puts this among the early ARIN-era allocations, from a period when a school with a strong computing programme could still ask for and receive its own autonomous system.
