From RFC1034/1035:
Note that while  upper and lower case letters are  allowed in domain names,
no significance is attached to the case.
From RFC1035:
For  all parts  of the  DNS that  are part  of the  official protocol,  all
comparisons between character strings (e.g., labels, domain names, etc. are)
done in a case-insensitive manner.
