About this network

ASN1 is the Montgomery County Hospital District, a Texas public hospital district that provides emergency medical services and public health programs for Montgomery County, north of Houston.

What it's used for

• Connectivity for the district's own facilities: EMS operations, dispatch and administrative systems on its own routed address space.
• A single small block for the district's own use. This is a public-sector end-user network, not a provider.

Notable

• A hospital district is a special-purpose unit of local government in Texas, funded by property tax, so this is public-sector address space rather than that of a private health system.
• The generic ASN1 handle is simply the district's first (and only) ASN, not a marker of any special status.
• ARIN registered this ASN to the district in 2009, so the low number is a reissue rather than early-internet history.

Interesting

• Public-safety agencies increasingly run their own AS because dispatch and EMS systems need connectivity that survives the failure of any single local carrier.
