Migrating DNS server to Linux

Hello everyone.

We are using INFOBLOX device in our company as our DHCP/dns server but this device is giving us some issues related to dns resolvers.*

We are a big environment, and have planned to setup a dns server on CentOS linux migrating it from infoblox device.*

I have seen linux dns servers in small and medium environments. But I am still thinking to give it a try in our environment thinking of the possible repercussions. We have multiple vlans and domains configured.*

I found one dns file from infoblox device which has the following configuration: (just attaching a part of it)*

Code:zone "1.x.x.in-addr.arpa" in { # 1.x.x.in-addr.arpa

* *type master;

* *allow-update { key DHCP_UPDATER_default;* };

* *allow-transfer { x.x.x.x; x.x.x.x; x.x.x.x; };

* *notify yes;

* *};

* *zone "3.x.x.in-addr.arpa" in { # 3.x.x.in-addr.arpa

* *type master;

* *allow-update { key DHCP_UPDATER_default;* };

* *allow-transfer { x.x.x.x; x.x.x.x; x.x.x.x; };

* *notify yes;

* *};

zone "example.com" in { # example.com

* *type slave;

* *masters { x.x.x.x; };

* *allow-update-forwarding { key DHCP_UPDATER_default;* none; };

* *allow-query { any;};

* *allow-transfer { x.x.x.x; x.x.x.x; };

* *file "db.example.com._default";

* *notify explicit;

* *};

* *zone "mydomain.com" in { # mydomain.com

* *type master;

* *allow-update { key DHCP_UPDATER_default; x.x.x.x; x.x.x.x;* };

* *allow-transfer { x.x.x.x; x.x.x.x; x.x.x.x; x.x.x.x; };

* *notify yes;

* *};

* *zone "_sub.mydomain.com" in { # _sub.mydomain.com

* *type master;

* *allow-update { x.x.x.x; x.x.x.x; x.x.x.x;* };

* *allow-transfer { x.x.x.x; x.x.x.x; x.x.x.x; x.x.x.x; };

* *notify yes;

zone "newdomain.com" in { # newdomain.com

* *type master;

* *allow-update { key DHCP_UPDATER_default; x.x.x.x; x.x.x.x;* };

* *allow-transfer { x.x.x.x; x.x.x.x; x.x.x.x; x.x.x.x; };

* *notify yes;

* *};As you can see from above configuration file, we have multiple domains and subdomains as forward entries and multiple subnet vlans in reverse entries.*

Can I add all the above configuration in single dns server on centos?

What do you suggest?? And what sort of configuration should be followed?? Should I have 2 separate physical servers one master and other slave?

Please advice.
