Network type: hosting
AS13720 announces 18 IPv4 prefixes covering 16,128 addresses and 0 IPv6 prefixes.
About this network
Two addresses answer with a hostname whose last label is not a real top-level domain, and four company names share one AS.
What it's used for
- An online game publisher's network. 16,128 addresses across twenty-three IPv4 prefixes, five observed BGP neighbours, and no IPv6 announced.
Notable
- 64.37.132.128 and 64.37.138.128 both answer as unusable.network.descriptor, which cannot resolve as a domain.
- Both are the first address of their range, the one a network cannot assign to a machine.
- Other addresses answer as ip-133-126.station.sony.com, naming a former parent company's brand.
- Netnames are VERANT-NETBLK1 and SOE-NETBLK2, naming two earlier companies.
- Registrants on the newer blocks list the current company and a former one after a semicolon.
Interesting
- A reverse zone that labels unusable addresses with a made-up name is a generator being careful. It fills every slot in the range, and rather than leave the unassignable ones blank it says so in words, in a domain chosen so nothing will ever look it up successfully.
- Four company names live in this one AS at once: the handle, the holder, two netnames and a hostname each name a different era of the same business.
- Games of this kind run persistent worlds where players are connected for hours, so an address change is disruptive in a way it is not for a website. That is why space acquired three owners ago is still in use under the same numbers.
