Domain names disappear extremely fast. Many people claim that all the good domain names are gone. I doubt that — but it is probably true that most good domain names that are descriptive of products and services have been taken. If you want a domain name for your site, I suggest you act now, or face the anguish of having lost that name later. After all, US$10 (more or less) for a year's ownership of the name is rather cheap when you realise that you're securing a good name for your website.
The character set allowed in the Domain Name System is based on ASCII and does not allow the representation of names and words of many languages in their native scripts or alphabets. ICANN approved the Internationalized domain name (IDNA) system, which maps Unicode strings used in application user interfaces into the valid DNS character set by an encoding called Punycode. For example, københavn.eu is mapped to xn--kbenhavn-54a.eu. Many registries have adopted IDNA.
A great domain name is a concise, easy to type, and memorable URL that reflects your brand or your website’s subject matter. Avoid using hyphens, strings of numbers, or unnecessary words to make it easy for your visitors to remember and find your website. Remember: A great domain name is one that your visitors can type correctly on their first try.
