About this network

NCIH is the autonomous system of the State of North Carolina's State Telecommunications Services, the network arm of the state's Department of Information Technology. The handle preserves the name of the North Carolina Information Highway, the state's long-running government network.

What it's used for

AS6559 carries traffic for North Carolina state government. It originates a large block of state-held address space, including several legacy /16s (152.31.0.0/16, 152.34.0.0/16, 149.168.0.0/16, 199.90.0.0/16, 204.211.0.0/16, 207.4.0.0/16) totalling roughly 410,000 IPv4 addresses. Reverse DNS resolves to state agencies, for example hosts under dhhs.nc.gov for the Department of Health and Human Services.

Notable

This is a government address, not an eyeball or hosting one: the users behind it are state agencies, their staff and their public-facing services. The unusually large IPv4 holding is a legacy of early state-government networking, when address space was easy to obtain in /16 units.

The AS was registered with ARIN in 1996, in line with the era when state networks were being consolidated into single routed backbones.
