About this network

Ninety-eight thousand addresses in two routes, one of them still named after the brand the company used to have.

What it's used for

• A mobile operator's network. Two IPv4 prefixes and one IPv6 /29 announced from Switzerland, ninety-eight thousand three hundred and four addresses, across a hundred and twenty-nine observed BGP neighbours.

Notable

• The whole IPv4 footprint is a /16 and a /17, announced whole with nothing broken out of them.
• One netname is a country code and the current brand, with no date. The other is a country code, a previous brand and a date from the year two thousand.
• The holder string prefixes the current brand with a country code before repeating the company name.
• The IPv6 allocation is a /29, the size given to operators expected to number a whole subscriber base.
• A hundred and twenty-nine neighbours is heavy interconnection for a network announcing two routes.
• Six addresses were queried for reverse DNS and none returned a name.

Interesting

• Two routes for a hundred thousand addresses is the opposite of what most operators this size do. Every other network here is split into dozens of pieces; this one has kept its announcements whole, which is easier on everyone else's routers and takes discipline to maintain.
• A netname is the only field nobody has to update after a rebrand, so it is often the last place the old name survives. Here it has outlasted two changes of owner.
