About this network

FREDERICK-MEMORIAL-HOSPITAL belongs to the Frederick Memorial Healthcare System of Frederick, Maryland — the not-for-profit hospital and health system now trading as Frederick Health. It is a minimal enterprise AS.

What it's used for

RIS sees a single IPv4 prefix, 208.253.115.0/24 (256 addresses), no IPv6, and one observed neighbour. The prefix is registered in ARIN to Frederick Memorial Hospital, so the announcing organisation is also the registrant. The network handle is UU-208-253-115, a name inherited from UUNET-era address administration; that is a registry artefact of where the block originally came from, not evidence of a third party holding it today, and the org on the record is the hospital.

A hospital system's routed space is a small internet edge: published web presence, patient-portal and payer-facing endpoints, mail, and site-to-site or remote-access VPN terminations. Clinical systems themselves live on internal networks behind that edge. Nothing in the routing suggests otherwise — 256 addresses cannot carry a hosting estate, and there is no customer cone.

Notable

One observed neighbour is unusual even for an enterprise. Most organisations that bother with an AS number do so specifically to multihome, and would show two or more upstreams; a single adjacency means either one transit provider or a second path that RIS simply does not observe from its collectors. Either way, this is not a network selling connectivity to anyone.

Interesting

Healthcare providers are well represented among small legacy-number enterprise ASes: independent hospitals were early adopters of provider-independent space because clinical and payer connections cannot tolerate renumbering. The brand has since modernised to Frederick Health while the registry, as usual, still records the older name.
