Quite by chance, I was doing a search of various combinations on Porkbun this morning, and put in my initials (3 letters = first/middle/last names) and to my surprise the
.one domain came up as available.
There are no restrictions on it's use, the price is (currently) cheap to register and also to renew - $7.84 per year with Porkbun.
Anyone else got a .one domain?
