well - it doesn't work for you yet doesn't mean it works for noone :)

I guess your local winxp-dns-client-cache is playing fool with you - try to
ping irc.cr.gt 
ipconfig /flushdns
ping irc.cr.gt
(probably repeat the flushdns and ping loop some more often) and you'll see it's
round robin.

after all it's the clients decision which A record it gets returned it uses and
there are only small possibilities in "normal" nameservers like pdns to specify
which clients should get which IPs (eg. based on networkdistance or similar).

again - use *nix and you'll achieve the more real-world-examples - even when
