Ubuntu 14.04 DNS configuration

[sashi4]

Hi everyone,

I am given a task to configure a pair of DNS servers, (ns1) & (ns2). ns1 will be sitting at the data center & ns2 will be sitting in my office. Both of these machines will running mail services, (mx1) & (m2).

ns1 - 210.x.x.x (master)
mx1 - 210.x.x.x (backup mx with priority set as 20)

ns2 - 122.y.y.y (slave)
mx2 - 122.y.y.y (primaxy mx with priority set as 10)

My doubts are is that, is it even possible to configure DNS forward & reverse zone files with IP address of different range? Somehow rather, i have created both the forward & reverse zone files for ns1, can someone please guide me in the correct dirrection?

143     IN      PTR     www.example.com.
143     IN      PTR     ftp.example.com.

Can someone please help me to check if these zone files are properly configured? Thank you.
