About this network

Seven hundred and forty-five thousand addresses across a hundred and twenty-five prefixes, behind one observed neighbour.

What it's used for

• A mobile and fixed operator's network. One hundred and twenty-five IPv4 prefixes and eight IPv6 prefixes announced from Turkey, seven hundred and forty-five thousand four hundred and seventy-two addresses, through a single observed BGP neighbour.

Notable

• Most blocks share one netname, written out as a sentence about customer address pools with hyphens where the spaces would be, repeated identically on block after block.
• The rest carry a country code, a four-letter contraction of an earlier network brand, and a date.
• The registrant on every block is a phrase naming an abuse contact rather than a company or a role code.
• The eight IPv6 prefixes are nested pieces of one range, from a /33 down to a /39 and back out to a /34, carved out of each other rather than sitting side by side.
• Three of eighteen queried addresses answered, each with the word for a host followed by eight digits that bear no relation to the address itself.

Interesting

• A national operator showing one neighbour means the view is partial, not that the network has one upstream. Route collectors see what they are peered with, and a carrier this size sells transit to networks that never appear in the same table.
• Reverse names built from an internal subscriber number rather than the address are a billing system writing DNS, which is why they look random.
