When surfing on the www, I regularly use the same domains: .co.uk, co.nz,
myprovider.extension,...

Is it possible to make a local domain alias?

I know it is possible to make a domain alias for an IP number by editing the
HOSTS file, but this is not very handy for me, since I have to add all the
websites I'm visiting.

Example: I want ".prov" to be the alias for "myprovider.com", so if I visit
"http://www.prov", I got redirected to http://www.myprovider.com. Same for
http://webmail.prov that will redirect to http://webmail.myprovider.com.

Another example. I want .cu to be the alias for .co.uk, so I can reach
http://www.company.co.uk by http://www.company.cu

This should be local. Of course, I don't think a global solution is possible
;-)

TIA
