I have a very quick question regarding case sensitive Greek hostnames.
For example, if I wished to register the hostname using the Greek letter omega Ω, like so:
ΩΩΩΩ.com, it would in actual fact appear as the lower case version: ωωωω.com.
In English of course, this is also true, where E would become e for example.
It is not a problem if it is to be read as a language, but if the purpose of this is to use omega as the symbol 'Ω' in the hostname rather than a letter, then it is problematic.
Is there any way around this, in order to maintain the uppercase letter? Are there domain registering sites that offer this type of service?
Answer
The Internet standards (Request for Comments) for protocols mandate that component hostname labels may contain only the ASCII letters 'a' through 'z' (in a case-insensitive manner), the digits '0' through '9', and the hyphen ('-'). The original specification of hostnames in RFC 952, mandated that labels could not start with a digit or with a hyphen, and must not end with a hyphen. However, a subsequent specification (RFC 1123) permitted hostname labels to start with digits. No other symbols, punctuation characters, or white space are permitted.
Hostname is Case Insensitive.
