We have a mixed NW 6.5/7.0 network. I am running DNS/DHCP Management
Console version 6.5 SP2.

One of my subnets needs to be expanded. I have read that I can delete
the existing subnet and create a new one that covers more addresses, but
I have only 10 more that are contiguous to the existing, original range
of 40 addresses.

Can we create two separate subnet ranges inside the same network? For
example, .50-.100 and .175-.225?

Thanks for help and suggestions.
