Yes. You can do this by changing the nameservers of haxfb.com to use ours, and adding it as a "parked" domain. Our nameservers are:
ns1.x10hosting.com
ns2.x10hosting.com
Once you have done this, you might need to change the configuration of any software you are using, so that it is using the new site URL.
how do i set server stuff. and I set a parked domain to HaxFB.com, but when I load the page, it shows up as haxfl.x10host.com still. I want it to stay HaxFB.com
Please could you confirm that you have changed your domain's nameservers to ns1.x10hosting.com and ns2.x10hosting.com? Since your domain appears to be with 1&1, this guide might help:
