But you're not allowed to, not because of the DNS rules but because of the hostname rules and a suggestion in the DNS specification that things will go better if you follow the hostname rules too. Why not relax that restriction? Why should we be beholden to old-timey restrictions? > For IDNs, must be valid a-label and u-label Why? That seems like it's "just" a policy preference. Why should the IETF have anything to say about it? Why shouldn't the top level labels also conform to JFC Morfin's Intersem plans, using multiple [a-z][a-z]-- prefixes?

Validation of TLDs > Application developers should not make assumptions about the composition of TLDs, or the frequency in which they are allocated. if validation is required then looking up the entry in the DNS is a foolproof way to know if a TLD has been allocated. Consideration should be made to reduce queries to the root. Static lists should be avoided. > Note that we already have an RFC that says roughly what (3) says, and so we don't need to say it again.
