in thread [OT] A New Everything ?
Yep, domain names are case-insensitive, but in most cases shown in lower-case.
It leads to the odd situation where in an email address, the part after the @ is case-insensitive, but the part before the @ is theoretically case-sensitive. (Depends on how the server treats it. Most treat it case-insensitively.)
