AS14336 — AS-1148

AS14336 announces 2 IPv4 prefixes covering 2,048 addresses and 0 IPv6 prefixes.

About this network

Two blocks that touch and still cannot be announced as one.

What it's used for

• A provincial health records agency's network in Canada. 2,048 addresses across two IPv4 prefixes, with one observed BGP neighbour and no IPv6 announced.

Notable

• 198.169.36.0/22 and 198.169.40.0/22 are adjacent, and both carry the netname NETBLK-EHEALTHSK.
• The AS handle is AS-1148, a number unrelated to this AS number.
• Six addresses were queried for reverse DNS and none returned a name.
• The AS first appeared in routing on 2002-09-28.

Interesting

• The two blocks sit end to end and still need two announcements, because combining them would require a larger block starting where neither of these does. Merging only works when the pieces fall on the right boundary, and here the first one starts four blocks past it. Adjacency is not enough.
• The handle referencing a different number is a leftover from an earlier record. Handles are chosen by the applicant, they are rarely revisited, and they end up pointing at whatever the organisation was tracking at the time.
• A single upstream for a provincial health service is thin, though a network like this usually reaches its hospitals over circuits that never appear in the public routing table.
• Nothing published in reverse DNS, which is the correct answer for a network holding medical records.
