okay, just readed this today, still have problems with some zones that  
need to be defined in named.conf for hostnames not lokal :/

a example is that does not being found if i remove it  
in named.conf as forward, is there a way i can debug this in verbose ?

when i had a ip in 80.x.x.x there was nearly none problems with dns,  
but after i get one new ip in 2.x.x.x then there is half of public dns  
failing :/
