About this network

Three different brand names across the holder, the handle and the reverse DNS, on one hundred and sixty-five thousand addresses.

What it's used for

• A hosting and connectivity provider's network. Thirty IPv4 prefixes and seven IPv6 prefixes announced from the Netherlands, one hundred and sixty-five thousand eight hundred and eighty-eight addresses, across two observed BGP neighbours.

Notable

• The holder is one company, the AS handle names a telephone operator's hosting arm, and the reverse names sit on a third domain again.
• Every netname follows one template: a country code, the holder's brand with a digit one, and an eight-digit date. The dates run across a decade, giving the order the blocks were taken in.
• One block's registry lookup failed, so its details are unknown rather than absent.
• The IPv6 holdings are a /29, four /32s and a /48, which is a provider allocation, four ordinary ones and a single site.
• Three of eighteen queried addresses answered, and two of the three names read as a phrase about being routed rather than identifying a machine.

Interesting

• One of those names is the first three octets reversed in front of the phrase; another is the phrase on its own with nothing in front. A wildcard record answers for anything unnamed, which is why an address can return a sentence with no address in it.
• Two upstreams for one hundred and sixty-five thousand addresses is unusually few, and it is what a network looks like after its parent becomes its transit.
