AS13246 announces 2 IPv4 prefixes covering 3,072 addresses and 1 IPv6 prefixes.

About this network

Fifteen IPv6 announcements against three IPv4 prefixes, each twice the size of the last.

What it's used for

• The network of a German domain registrar and hosting company. 3,328 addresses across three IPv4 prefixes, fifteen IPv6 prefixes, and four observed BGP neighbours.

Notable

• The IPv6 list runs 2a02:2940::/46, 4::/46, 8::/45, 10::/44, 20::/43, 40::/42, 80::/41, 100::/40, 200::/39, 400::/38.
• Netnames are DE-KEY-SYSTEMS-20090302 and DE-KEY-SYSTEMS-20161213.
• 80.86.1.0/24 is netname NH-HOSTING-M, registered to Netzhaus AG Hostmaster.
• The AS handle is INETWIRE-AS Key-Systems GmbH PartnerGate, with two spaces before the last word.

Interesting

• The doubling cascade appears again, and this one starts with two prefixes of equal size before the doubling begins. That first pair is the remainder that could not be expressed as a single prefix, which is exactly what a range splitter emits at the start of an interval.
• Fifteen IPv6 routes for a network with 3,328 IPv4 addresses inverts the usual proportion, and every one of them occupies a slot in every router that carries a full table.
• A block registered to a separate company sits alongside two of the holder's own. The AS announces all three, so what is announced and what is registered part ways on a third of this network.
