Info

Explanation:

192.168.1.0 & 192.168.1.255 are broadcast addresses, and would not be used.

192.168.1.1 - existing servers are 1-10, so this address is already in use. 192.168.1.58 - is already in the scope (remember that 1-55 are excluded, so 56-254 are dynamic and can't be used unless a reservation is set).

192.168.1.25 - is the only usable & available address left!
