So you have found the perfect domain for your website but discovered it is not available? Unfortunately this happens sometimes, even with a new top-level domain like .pro. It is still more likely that your domain name will be available with a .pro extension than a .com
extension, but it is not guaranteed. 1&1 IONOS understands that this is frustrating, which is why 1&1 IONOS will help you find an alternative that is as close as possible to the original. This is why it is a good idea to be flexible when choosing your domain name, and to prepare a few different options in case your first choice isn't available. Because using a domain that is already being used by an existing company could cause legal issues, 1&1 IONOS has created the domain checker
to protect the reputation and future of your company, and ensure you do not use another business's domain name.
