AS6922 — TEXASAGENCYNET - Texas Department of Information Resources

AS6922 announces 46 IPv4 prefixes covering 304,640 addresses and 37 IPv6 prefixes.

About this network

TEXASAGENCYNET is registered to the Texas Department of Information Resources (DIR), the state agency that runs shared technology services and statewide network contracts for Texas government.

What it's used for

• Internet connectivity for Texas state agencies. This is the routed side of the state's agency network, carrying traffic for the departments and boards that buy their connectivity through DIR.

Notable

• Almost all of the announced address space, including the IPv6 allocation, is registered to the University of Texas System under THENET- netnames. THEnet, the Texas Higher Education Network operated out of UT System, historically provided the backbone that state agencies rode on, and the addressing still reflects that arrangement.
• The result is a government-agency autonomous system announcing university-held address space. Both facts are true and neither should be collapsed into the other.
• Roughly 90 prefixes and over 300,000 IPv4 addresses make this one of the larger US state-government networks by announced space.
