I want to buy a domain name without hosting. Is that possible?

Currently, no.

It is our goal to be able to offer a standalone domain service in the near future.

Currently, one thing we can recommend is that you try out our hosting. Hosting is our specialty, after all. If you purchase a domain name with hosting, and decide to stay with eleven2, great. If you decide to use another host, you can still continue with an active domain from eleven2 You can continue domain name registration service through eleven2 as long as you choose, regardless of whether or not you still have web hosting through eleven2.
