DHCP Scope is running out
Our DHCP Scope for our curriculum network is bout to run out, and soon there wont be any IP addresses available for the new clients (as we are going to buy another 50 PCs for our new ICT suite).
The DHCP scope is configure as:
IP 10.8.100.0 to 10.8.100.254
Subnet mask 255.255.255.0
Since 24 bits are assigned to the network part it only gives us 254 hosts.
I need some guidance in how to go about changing the scope to (16 bits for network part of the IP rather than 24), and what are the factors that i need to consider (such as changing router and switches configurations, software that uses IPs of the servers, web applications, etc, etc) before changing anything as it is a live network, and i can not afford for anything to go wrong.
