if i buy a domain name does it come up with a box for me to type into the page it should go to?
thanks for any help
You'll probably get a control panel so you can assign the dns records. You set up A records to map to your site, and MX records map to your mail server.
o crumbs sounds hard or is it actualy quite easy?
It's easy using control panels.
Check with your hosting service provider and in the search box (hope they have one) search for DNS. If the host is good it will provide you per step instructions on how to change. Not difficult
