Finding a domain name: a practical checklist
A good name is memorable, easy to say and easy to type. Here is how to evaluate your ideas.
Read guide ↗The essentials
.at supports permitted international characters. An umlaut address and its spelled-out alternative are separate domains. Choose a primary address deliberately and test website, email and forms with the services you actually use.
What IDN and Punycode mean
A domain with international characters is called an IDN. For technical use it can be represented in ASCII, with a domain label starting xn--. This Punycode form represents the same international name. Seeing xn-- in a technical interface therefore does not automatically indicate another registration. Copy the name carefully and check which form a particular service requires.
An umlaut and ae, oe or ue are not the same name
A fictional project might choose between a name containing ö and the equivalent spelling with oe. These are different names and therefore separate domains if both can be registered. Registering one does not include the other. Check each before choosing a primary address. If you want both, budget for registration and later renewal of each name.
Test the primary address with real contacts
An umlaut can look natural on German-language printed material. A spelled-out version may be easier in international conversations or on keyboards without German characters. Try the address in the situations where you share it: by phone, on business cards, on a smartphone and in a booking form. Choose the version your actual audience can use most reliably and communicate it consistently.
Check email and external services separately
Browser support for an umlaut domain does not prove that every email service and contact form supports the same spelling. Check your mail service’s requirements before setup. An ASCII domain can be a practical primary address for email shared internationally. Test receiving, sending and replying with your contacts’ services before permanently using the address on invoices or printed material.
Prepare a domain for email ↗Direct multiple variants cleanly to one website
If you register both spellings, choose one primary address. A suitable website or redirect service can permanently send the second to it. This requires a real HTTP redirect and working HTTPS on both addresses. DNS alone does not redirect visitors to a page path. After setup, check that subpages such as your contact page reach the correct destination. atdomain.at manages DNS and nameservers; choose the redirect service separately.
