I have a server with only a NIC. I have manage two ip address for this
NIC.

In the DHCP/DNS utility I can manage the zone but
is it more correct if I create a zone with 2 resoucerecord type A
or
I must create two zones and each zone contain only a record type A?

My server (named S1) has 10.10.2.2 and 192.168.3.4.
My zone is named ZONA1 and S1 has two resource record
OR
I have two zones:
ZONA1 and S1 has only ip 10.10.2.2
ZONA2 and S1 has only ip 192.168.3.4

If I ping the name of my servre from pc client from subnet 10.10.x.x once
I have as answer 10.10.2.2 and once I have 192.168.3.4.
Why?
Is it correct?

thanks
