file zone syntax

[John Smith]

ok here it is...

www.mydomain.com.		IN	A 		192.168.0.1
www.mydomain.com.		IN	A		192.168.0.2
www.mydomain.com.		IN	A		192.168.0.3
mail.mydomain.com.	IN	A		192.168.0.1
mail.mydomain.com.	IN	A		192.168.0.2
mail.mydomain.com.	IN	A		192.168.0.3

mydomain.com.		IN	MX	10	mail1.mydomain.com.
mydomain.com.		IN	MX	10	mail2.mydomain.com.
mydomain.com.		IN	MX	20	mail3.mydomain.com.

www.mydomain.com.		IN	CNAME		mydomain.com.
mail.mydomain.com.	IN	CNAME		mydomain.com.

assumin that i have other recods such as SOA and NS and

192.168.0.x is real internet ip and
192.168.0.1 is mail1.mydomain.com and web1.mydomain.com
192.168.0.2 is mail2.mydomain.com and web2.mydomain.com
192.168.0.3 is mail3.mydomain.com and web3.mydomain.com

i'm using mydomain.com as a just something instead of my real domain
and 192.168.0.x as just ip instead of my real ips
