AS15739 announces 2 IPv4 prefixes covering 512 addresses and 1 IPv6 prefixes.

About this network

Five hundred and twelve IPv4 addresses and twenty IPv6 routes, with an exchange and a delivery network in the netnames.

What it's used for

• A technology park's network. Two IPv4 prefixes and twenty IPv6 prefixes announced from Lebanon, five hundred and twelve addresses, across four observed BGP neighbours.

Notable

• The IPv6 announcements climb from a /48 through /47, /46, /45, /44, /43, /42, /41 and /40, each step twice the size of the last.
• That is ten times as many IPv6 routes as IPv4 addresses would suggest, on a holding of two /24 blocks.
• One netname is a three-letter abbreviation for an internet exchange, the other names content delivery subnets in mixed case, so both fields describe a function rather than an owner.
• Neither block lists the holder. The only contact on both is an operations centre belonging to another company.
• Six addresses were queried for reverse DNS and none returned a name.

Interesting

• The doubling staircase turns up for the third time in this stretch of numbers, here on a network with almost no IPv4 at all. It is arithmetic rather than style: any range whose edges miss a block boundary gets tiled this way.
• An exchange and a delivery network inside one small holding is a technology park doing what it was built for. The addresses are shared infrastructure for whoever is on site, which is also why the operator's contact is somebody else's.
