reverse Zone example!

[Alans]

Hello,
I thought the reason is because it's weekend :)

I have a DNS for domain example.com
One of my customers have a domain customersdomain.com and they have their
own DNS (forward lookups)
They want me to add ptr (smaller than /24) for them

$TTL    1W
$ORIGIN xx.yy.zz.IN-ADDR.ARPA.
@       IN      SOA     ns1.example.com. root.example.com. ( <<<<<<---- is
it correct?
                        2008082707
                        15M
                        10M
                        4W
                        1W )
 
xx.yy.zz.IN-ADDR.ARPA.  IN      NS      ns1.example.com.	<<<<<<-----
is it correct?
 
1                     PTR     ns1.customersdomain.com.
2                     PTR     ns2. customersdomain.com.

I only want to make sure that SOA and NS records are correct or is there any
wrong with above configuration?

Thanks,
Alans

FYI, the reason that you haven't gotten a useful answer yet is that you 
haven't provided us enough information.

In order to answer your question we need to know what kind of address 
blocks you're attempting to set up DNS for. I suspect that you're 
probably trying to set up DNS for something smaller than a /24, is that 
right? If you can respond with more details, it's likely we can help you.


Good luck,

Doug
