AS16153 announces 1 IPv4 prefixes covering 65,536 addresses and 0 IPv6 prefixes.

About this network

Sixty-five thousand addresses in one block, behind a single observed upstream.

What it's used for

• A regional health service's network. A single IPv4 prefix announced from Spain, no IPv6, sixty-five thousand five hundred and thirty-six addresses, through one observed BGP neighbour.

Notable

• The whole holding is one very large block, the biggest single allocation size in common use, and there is nothing else attached to the number.
• The netname is three letters that appear nowhere else in the record followed by the service's own initials.
• The first contact is a network administrator role belonging to the regional government's technology and telecommunications centre, written in the regional language rather than the national one.
• The health service is listed second, and an abuse contact third.
• Three addresses were queried for reverse DNS and none returned a name.

Interesting

• Health services accumulate addresses because every hospital, clinic and laboratory in a region ends up on the same network, and medical devices are numbered like computers even when they are effectively appliances.
• One upstream for a whole region's health computing sounds fragile, but a network like this mostly talks to itself. The external connection carries administration and referrals, and the clinical traffic never leaves the regional network at all.
