Unclassified ARIN
Summary
Novant Health
healthcare business internal us
The AS handle NOVANT-AS1 is operated by Novant Health Inc., a large integrated healthcare network serving North Carolina and South Carolina.
What it's used for
- The address space carries internal corporate infrastructure, evidenced by reverse DNS entries such as
boldnet.novanthealth.organdwww.mccardiology.com, which point to internal systems and specific medical departments. - The AS announces 1536 IPv4 addresses across 4 prefixes with only 2 observed neighbours, a ratio that indicates a small, isolated internal network rather than a transit or access provider.
Notable
- All four announced prefixes share the netname
NOVANTHEALTHand list Novant Health Inc. as the registrant, confirming full alignment between the routing announcements and the registry records. - The inventory consists of four contiguous IPv4 blocks within the 170.98.0.0/16 range, with no IPv6 prefixes announced, reflecting a purely IPv4 internal estate.

Internet exchanges
No exchange port on file. Many exchanges publish no participant list, so this is not proof of absence.
Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-11-13, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

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: 455 networks and 1,849 prefixes, as published 2026-11-13. 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.
