Is this true?You could also just point the nameservers to x10hosting and add a parked domain in CPanel, it works pretty much the same way.
So is parked domains just like masking the other domain or is it actually the proper domain?Yes. But I believe Park Domain is disabled ( unless they reenabled recently )
Thats why I stated what I did. I haven't heard any updates on this. But yes, normally either way would work.
