It looks like black-hat host YoHost.org is on the move to a set of IP addresses owned by "Dragonara Alliance Ltd" (dragonara.net) - a company that claims to be Swiss (and appears to use hosting in Switzerland) but is registered in the British Virgin Islands.
Dragonara claims to be a high-reliability host where clients can weather out DDOS attacks, which is a useful service. However, a lot of the sites it host seem to be quite dubious, and a lot of sites seems to be pushing "replica" (i.e. fake) Swiss watches. The fact that a Swiss company is hosting sites in Switzerland that appear to be selling fake Swiss watches is something that might end up in an interesting conversation with some Swiss lawyers.
The IP address range to look out for is 126.96.36.199 - 188.8.131.52. The sites listed below are for information purposes only, many may well be perfectly legitimate. If you have any observations, then please use the comments.
