Currently I have this network: 10.1.16.0/22. 10.1.16.0-10.16.17.254 are DHCP managed 10.1.18.0-10.1.19.254 are statically assigned If I need to expand it to: 10.1.16.0/20
- What is the best way to do it with minimal network disruption?
I am no subneting pro but: Currently you have half DHCP and half statics... How will it be with the /20? Still half/half?
$ ipcalc -nb 10.1.16.0/20 Address: 10.1.16.0 Netmask: 255.255.240.0 = 20 Wildcard: 0.0.15.255 => Network: 10.1.16.0/20 HostMin: 10.1.16.1 HostMax: 10.1.31.254 Broadcast: 10.1.31.255 Hosts/Net: 4094
A /20 half/half would give:
10.1.16.1-10.1.23.254 10.1.24.1-10.1.31.254
- If I keep some machine with 22 subnet mask, will it still be able
to talk to the other machines in it's range?
They would talk to 10.1.16.1-10.1.19.254 ones, but would go for the gateway for 10.1.20.1-10.1.31.254
