Autonomous system
AS36850 UNC-CH
Unclassified ARIN
Summary
University of North Carolina at Chapel Hill
education research campus ncren
The AS handle UNC-CH is held by University of North Carolina at Chapel Hill.
What it's used for
- The address space carries campus and research network infrastructure, evidenced by netnames such as
UNCCH-NET,NCREN-B19,NCREN-B23, andUNCCH-NCREN-IPV4-1through3. - The network announces 203,264 IPv4 addresses across 7 prefixes and 3 IPv6 prefixes, while maintaining only 1 observed neighbour, a ratio that indicates an internal access or campus network rather than a transit provider.
Notable
- All registrants for the announced prefixes are listed as University of North Carolina at Chapel Hill, fully agreeing with the AS holder.
- The address inventory consists of three large /16 blocks and several smaller /20, /22, and /23 blocks, reflecting a finely subdivided internal corporate estate typical of a large university campus.

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: 442 networks and 1,772 prefixes, as published 2026-10-15. 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.
