Dear Suresh,
I am very interested to help you, as I have been System Adminitrator for
Unix System and
done sometime with DNS management, However Your data is not clear enough,
and i get confused
from your explanation, therefor I can't reply with useful info.
1) Please provide more real data to analyzi for example does two sites have
exact name ? or it's different ?
www.a.com and www1.a.com could be the same IP could be different.
2) I could have mx and DNS entry different for example :
www.ong.net. IN A 202.154.1.1
www1.ong.net. IN A 202.154.1.2
You see now ? it's different for MX it could be
ong.net. IN MX 10 202.154.1.1
branch.ong.net. IN MX 20 202.154.1.2
Meaning :
1) Mail with ong.net domains go to email server 202.154.1.1
2) Mail with branch.ong.net domains go to email server 202.154.1.2
Btw I am not sure what you're asking, here's a general point
