This is what I got as I went through the order process so it looks like you can.
* A domain registration period is one year (.com/.net/.org/.info/.name). A domain name must be paid for in full at the beginning of the registration period.
* Domain name registration fees are not refundable.
* Paid domain names can be transferred externally anytime, no release fees.
* An included domain (.com/.net/.org) means the price of this domain is included in the package. The top level domains, .name/.info, cannot be used as included domains.
* Invoices for domains are created separately from invoices for packages and may take up to 5 weeks from the date of Package Registration to be generated.
* Domain names are registered to the customer unless otherwise stated.
I didn't really experience any problems with their registration process.
Tonight, I started the process of trying to point my domain to a different web host. I wanted to try a paid host, and see if my web site loaded any faster.
Part of my problem, however, is that I have no real experience in changing web hosts and changing domain pointers. I do not find 1and1.com's FAQ's to be overly helpful, primarily because the FAQ does not always match the actual menus.
Literally, I can't figure out how to just change the DNS settings. When I go in and click the box beside my domain name, the functions that I need to select from that domain are then gray'd out, and it won't let me access them.
I sent them e-mail just a little while ago, so I don't know when of if they will respond to it.
When I first started using 1and1.com as a web host, I took advantage of their free 3-year promotional deal, and they responded very swiftly to the first e-mail I sent their support staff.
Since that time, a few months have gone by, and I have e-mailed their support staff several times, but not a lot. Sometimes, I have gotten a response, and other times I haven't.
If the only issue is registering a domain name through them, my experience would indicate to me that that shouldn't pose a problem. Changing DNS settings, however, appears to be problematic. I wouldn't rate that aspect of 1and1.com's domain manager very highly. It leaves a lot to be desired, from the standpoint of user friendliness.
