We use Window 2008 servers. Our firewall is maintained externally they handle all the routing and I don’t have access to the firewall. The existing IP subnet for our network is 10.14.112.0/22 , which was allocated to our network 9 years ago and we have only 1022 IP addresses at the moment.
Now we are going to expand our network within our premises and we will have more devices on our network like laptop , tablets etc.. In this case as a future proof I think it will better to have a IP subnet which can give us more IP address.
I am planning ask our firewall team to allot me a new IP subnet 10.14.112.0/20 and this will give me 4094 IP address.
If they "yes it is possible" and if they configure and allot this new range for our network.
Is this a good plan to move forward to have more IP address for our network ?
For a smooth transition , what are the precautions that I need to be take within my LAN if I change the IP scheme
