a bit of theory about PTR records requested

[Martijn van Katwijk]

Hi,

I also have zones like this:
domain.com.	IN	A	192.168.1.60
www		IN	CNAME	domain.com.

In fact I have quite a lot of these, all pointing to a single virtual name 
based webserver with only a few IP nrs assigned to it.
So I have a lot of A records to a single IP nr.

Do I have to configure a PTR for each A record? Or is that meaningless.

Thanks,
Martijn
