AS11803 — OMNICELL

AS11803 announces 3 IPv4 prefixes covering 1,024 addresses and 0 IPv6 prefixes.

About this network

OMNICELL is Omnicell, Inc., the healthcare-automation company best known for automated medication dispensing cabinets and pharmacy management systems for hospitals. ARIN registered the AS in 2008 and lists it at 500 Cranberry Woods Drive in Cranberry Township, Pennsylvania — the former McKesson Automation / Aesynt site that Omnicell absorbed, not its corporate headquarters.

What it's used for

A single enterprise footprint, and a deliberately minimal one. RIS observes 1 IPv4 prefix — one /24, 256 addresses — no IPv6, and 1 observed neighbour. The /24 is registered in ARIN directly to Omnicell, Inc. under the company's own network handle, so holder, registrant and announcer are the same party.

Reverse DNS on that block resolves under nttgdca.com — NTT's Global Data Centers Americas. That does not make this an NTT network: Omnicell's /24 lives in NTT colocation space and wears the facility's default host naming. Announcing your own /24 from a leased cage is a common shape for a company that wants portable addressing without becoming a network operator.

What the space plausibly carries is Omnicell's own outward-facing systems — the link between hospital-installed dispensing systems and the vendor's back end, plus corporate services. It is not hosting, and there is no customer traffic on it.

Notable

256 addresses behind one upstream is about the smallest an AS can meaningfully be. The interesting thing here is the registry address: it points at an acquired automation business in western Pennsylvania rather than at Omnicell's own head office, which is how corporate acquisitions usually leave their mark on ARIN records.
