I'm no DNS expert, but I have a few suggestions.

your ISP's nameserver shouldn't be here, it should be in named.conf, see 
below.

You should have a reverse DNS zone here for carsten.peter.name

This looks wrong, but it could be a difference in our versions of bind. 
My bind9 zone looks like this:

$TTL    604800
@       IN      SOA     net.home. root.net.home. (
                        2003070410      ; Serial
                         604800         ; Refresh
                          86400         ; Retry
                        2419200         ; Expire
                         604800 )       ; Negative Cache TTL
;
        IN      NS      acephlaous.net.home.    ; name server
        IN      MX      10 mail.net.home.       ; Primary mail exchanger

mail            IN      A       209.67.232.227
antonov         IN      A       192.168.1.7
kalypso         IN      A       192.168.1.1
