I have a bind9 installation on my Debian Wheezy install.On this install I have a DNS-server which acts as the SOA for a domain, example1.com.My name server is also on the same domain, example1.com (see excerpt from db1.example.com below). This has been achieved by glue records at my hosting provider).Now I want to add another domain, example2.com to this bind9 installation, so that it is the master DNS-server for both domains.I already have:(from named.conf)zone example1.com {    type master;    file /etc/bind/db.example1.com;};(from db.example1.com)$TTL    604800@       IN      SOA     example1.com. root.example1.com. (                      1         ; Serial                 604800         ; Refresh                  86400         ; Retry                2419200         ; Expire                 604800 )       ; Negative Cache TTL;@       IN      NS      example1.com.Now, I tried to add another zone entry in named.conf and a file db.example2.com (corresponding to the db.example1.com). But that leads to bind failing to start.What is missing? Does the delegation (by ISP) of the domain example2.com have to be done before adding it to my DNS-server?
How to add another domain (SOA) to my bind9 installation when domain has not been delegated yet. What are the delegation steps?
