alt Hacker NewsI own a .name domain that is an initialism for my wife and I, and Namecheap never gave me any problems adding a record for vpn.mwai.name, for example. In fact I never even realized you could register a 3LD, much less that this was the intended(?) behavior.
The idea is:
* .name is open for everybody
* a company called "Global Name Registry" scooped up a BUNCH of common last names, including fraser.name
* Global Name Registry then sold access to neil.fraser.name for far cheaper than the fraser.name domain would cost on its own; someone else could also buy john.fraser.name or jane.fraser.name, so the single fraser.name domain that they owned could have dozens of customers associated to it. They worked with ICANN to allow each domain to have its own registered owner.
* The article in the OP bought neil.fraser.name and has used it for years
* Verisign bought Global Name Registry; later they realized, hey, we're sorta not making a lot of money on this idea, and we're spending a lot of time/resources maintaining these domains "for cheap" and chasing renewals, and not scooping up more customers. Let's just stop it and stop paying for fraser.name and the potentially hundreds of other domains we own.
* Neil Fraser, not the only Fraser in the world, is upset because he might lose the domain he's had forever
So one CAN buy the mwai.name domain, as you have, and continue using vpn.mwai.name just fine. It's just you can't "officially" start selling out these subdomains as a separate registrar entry.
