About this network

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 206.227.192.0/18 block 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.
