About this network

Four fifths of the addresses here sit in a /16 registered to a telephone company.

What it's used for

• A cantonal finance authority's network. Seven IPv4 prefixes and one IPv6 /32 announced from Switzerland, eighty-one thousand addresses, through two observed BGP neighbours.

Notable

• The largest announcement is a /16 whose registry entry names a carrier and that carrier's own address registry team, not the authority announcing it.
• The other five documented blocks share one identical netname, which ends in a two-digit number that matches none of them.
• One block's registry lookup failed, so its details are unknown rather than absent.
• Two neighbours carry eighty-one thousand addresses, which is a narrow connection for that much space.
• Eighteen addresses were queried for reverse DNS and none returned a name.

Interesting

• A carrier's block announced by a government AS is the ordinary shape of an outsourced network. The provider holds the addresses, the customer holds the routing identity, and the registry records only half of that.
• One netname repeated across five blocks of four different sizes means the operator treats them as one pool. The registry has no way to say that, so the netname carries the meaning instead.
• Sixty-five thousand of these addresses come from one grant and the remaining sixteen thousand from six pieces, which is two eras of address policy in one network.
