I can register a .uk domain, does this mean I can set any subdomain I like infront of it including .co?Or even .ac?Wouldn't this mean that anyone can get an .ac.uk domain by just having ac as a subdomain on a  .uk domain?Is a .co.uk domain all one TLD or is the .co just a subdomain preadded by domain registrars?
Which subdomains can I use when I register a UK domain (.co.uk, .ac.uk, etc)?
domains;top level domains
