AS14097 — COUNTRYMILE-ASN-01

AS14097 announces 1 IPv4 prefixes covering 2,048 addresses and 1 IPv6 prefixes.

About this network

Seventeen IPv6 announcements that halve, then double, describing one range exactly.

What it's used for

• A wireless internet provider's network. 2,048 addresses in a single IPv4 prefix, alongside seventeen IPv6 prefixes, with one observed BGP neighbour.

Notable

• The IPv6 blocks begin at 2606:44c0::/33 and step down through /34, /35 and /36, then climb again from /48 through /44.
• 38.199.8.0/21 carries the netname CMWI-CGNT-NET-1, which names the company, its carrier and a sequence number.
• Three addresses were queried for reverse DNS and none returned a name.
• The AS first appeared in routing on 2001-10-30.

Interesting

• The two halves of that sequence are one shape seen from both ends. Describing a span of addresses exactly in aligned blocks gives a descending run at the start and an ascending run at the finish, and the pattern here is a tool being asked to cover a range and announcing every piece it produced.
• One or two routes would carry the same traffic. Seventeen is the cost of automation nobody looked at afterwards, and it is paid by every router on the internet rather than by the operator.
• A wireless provider serving rural subscribers with a carrier-assigned IPv4 block and a very large IPv6 allocation is the modern shape of this business: the old addresses are rented, the new ones are free.
• One upstream means everything here depends on a single carrier relationship.
