zone "xyz.com" {

        type forward;

        forwarders {

Check the Nameservers (NS)

> set q=NS
> voidio.com
Server: rabbit.voidio.ch
Address: 193.247.121.196

voidio.com nameserver = lila.thenet.ch
voidio.com nameserver = rabbit.voidio.com
lila.thenet.ch internet address = 193.135.252.2
rabbit.voidio.com internet address = 193.247.121.196
