AS13829 — PIMACOUNTY

AS13829 announces 1 IPv4 prefixes covering 65,536 addresses and 0 IPv6 prefixes.

About this network

Fourteen prefixes, all inside one parent range, all one netname, and a single upstream behind all of them.

What it's used for

• A county government's network. 65,536 addresses across 14 IPv4 prefixes, one observed BGP neighbour, and no IPv6 announced.

Notable

• Every prefix begins 159.233, and together they account for the entire parent range.
• Every record that answered gives netname PIMACO, the county shortened to six letters.
• Sizes run from a /17 down to four /24s, with /18, /20, /21, /22 and /23 pieces between.
• One block's registry lookup failed and returned nothing.
• Eighteen addresses were queried for reverse DNS and none returned a name.

Interesting

• Splitting a whole parent range into fourteen announcements while sending them all to one upstream buys nothing in routing terms. Each piece takes a slot in every router on the internet, and with a single path there is no second route for any of them to prefer.
• Shapes like this usually come from internal segmentation leaking outward: departments were given their own pieces, and the pieces were announced individually because that is how they were configured.
• A county holding a full parent range dates the allocation to when local government could ask for one.
