sles, 0es2, zcm 10.3.1
NO windows domain controller

1. does the zcm server need forward and reverse lookups configured in dns
2. If so. we have computers that login to this server on multiple subnets, we configured the zcm server with multiple ip addresses "one for each subnet".
3. does the workstations have to have dns entries
4. is there a way not to use dns at all for the server but the ip address instead
