This is ok.
How can i use the same zone file for both internal and external 
clients ? Because here i need to maintain two files.

lets say for a domain.com i will have a zone file which will 
have both internal and external addresses. But when a query 
comes for abc.domain.com, it should be resolved to 192.168.1.10
if the request is from 192.168.1.5 and when a query comes for 
abc.domain.com from a public IP it should be resolved to the 
publicly addressable IP of abc.domain.com (lets say 
100.100.110.101). Is this setup possible with bind ?


Thanks
