So, what is the real IP address of that hostname?
m247.com comes up with a general cloud service website, perhaps the no-
mans-land prefix is a deliberate dead-end used by some things to
prevent out-of-network leakages?
A bit like how my DNS server is set to produce no-answer DNS lookups
for things like doubleclick domain names, and other pests. It kills
various snooping bugs on devices that you can't configure, like smart
TVs.
