Summary
State of North Carolina
government legacy
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.

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: 440 networks and 1,773 prefixes, as published 2026-10-13. 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.
