Hi all,

A client of mine has a website with a domain.
They claim that domains can't be hosted just anywhere, but have
to be on a host.

Can any of the UK webmasters here confirm or deny that? I can't seem
to find any information about it through Google. The only thing I
found, is that the domains are registered with Janet, but nothing
about the actual hosting.
