TraceRoute to AS Number 48666's six IPv4 addresses administered by MRS1 in Russia
Domain Dossier provides a means for finding out the path to a given IP address with the TraceRoute function, but there is the added benefit of anonimizing the IP address from which the trace is run.

Autonomous System Number 48666 is administered by a person known by the handle MRS1 from an office in
Moscow. Data on those hosted servers is posted at this link.

Looking at about the last ten steps in the route to the present six IPv4 addresses used by this group, it is clear that they share an essentially identical route, which helps to explain why a presumably simultaneous activation of the six requests in each series of HEAD / HTTP entries at MiDomane.com causes the six requests to be logged at the MiDomane.com server within just a few seconds.
The "rtt" hops are in milliseconds.
