AS6109 NDCHEALTH - NDCHealth Corporation
Unclassified ARIN
Summary
NDCHealth Corporation
enterprise legacy
NDCHEALTH is registered to NDCHealth Corporation, an Atlanta healthcare information-services company. The network carries a healthcare-IT business, not consumer or hosting traffic.
What it's used for
- Corporate and healthcare data-processing connectivity: the systems behind claims, pharmacy and provider information services that this line of business has long handled.
- Nearly all of its announced space comes from one contiguous block,
206.227.192.0/18, registered to the same organisation. That is the shape of a company that runs its own addressing rather than reselling it.
Notable
- An enterprise address: IPs here belong to a company's own back-office and processing systems. Healthcare data-processing networks are typically tightly controlled and see little general-purpose outbound traffic.
- The ARIN records for both the ASN and the
206.227.192.0/18block date to November 1995, which is a genuine mid-1990s registration rather than a later reissue.
Interesting
- The NDCHealth name is a survivor in the registry. The business descends from National Data Corporation, which spun its healthcare arm out as NDCHealth; that company was later acquired by Per-Se Technologies, and Per-Se in turn by McKesson. The routing records kept the old name long after the corporate one changed.

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: 447 networks and 1,843 prefixes, as published 2026-11-01. 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.
