[Latingp] ODG: ODG: Variants -- Case for Considering Upper Case

[Mats Dufberg]

Mirjana,

If you open the base RFCs of DNS, RFC 1034 and RFC 1035, you will find many examples of domain names, most of them real (at least at that time) I think. They are mostly written in upper case, e.g. A.ISI.EDU.

https://tools.ietf.org/html/rfc1035
https://tools.ietf.org/html/rfc1034

Over the years, domain names have been written in lower case, upper case and mixed case. And you still see that.

Dear all, 

Now I understand the point. My opinion that such cases cannot be prevented by developing any variants rules. This is the crime and should be punished accordingly.

you do not *register* domains in upper or lower case. The domain name is always case insensitive. You can simply try this out yourself.
If you go to
http://icann.org
or
http://Icann.oRg

It's all the same. Therefore you don't know, if some company simply always publishes its internet address in capital letters. Or mixed if they want to be very cool/hip/modern, whatever. ;-)

Therefore domain names can look the same, although they are different.

Cheers,

Michael
