AS15924 — BORUSANTELEKOM-AS Vodafone Net Iletisim Hizmetler AS

AS15924 announces 289 IPv4 prefixes covering 325,632 addresses and 38 IPv6 prefixes.

About this network

Five hundred and five IPv4 announcements for three hundred and twenty-five thousand addresses, an average of a few hundred each.

What it's used for

• A carrier's network. Five hundred and five IPv4 prefixes and fifty-three IPv6 prefixes announced from Turkey, three hundred and twenty-five thousand eight hundred and eighty-eight addresses, across one hundred and fifty-six observed BGP neighbours.

Notable

• Every netname follows one template: a country code, a five-letter contraction of the current brand, and a date. The dates span more than a decade of separate allocations.
• The first registrant on nearly every block is a backbone group named after a different company, with the current holder second. One block puts a job title first instead.
• The AS handle names that earlier company too, so the routing record and the registry agree with each other and disagree with the holder.
• The IPv6 prefixes are nested pieces of one range, running from a /41 down to a /48.
• One of eighteen queried addresses answered, and its name is a bare domain with no host label at all.

Interesting

• Five hundred routes for three hundred thousand addresses is aggressive splitting. Each announcement is a lever for steering traffic between upstreams, and a carrier with a hundred and fifty-six neighbours has that many decisions to make.
• The cost is borne by everyone else: each of those routes occupies memory in every router on the internet that carries a full table.
