Punycode & nslookup

[Joe Baptista]

You configure an idn zone the same way you do for any other - so I assume
your config below is correct - although the location of the master file
master/umlauttestäöü.de.hosts contains non ascii char I don't think that is
an issue in todays unix/linux environment. It would of been a problem in the
old days.

As for you question concerning the browser converting the domain to punycode
before asking a nameserver - yes that is what some browsers do. I'm not sure
why because it must confuse some users when that happens.
