Hi all, Can pls share your experience on this? 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 1. What is the best way to do it with minimal network disruption? 2. If I keep some machine with 22 subnet mask, will it still be able to talk to the other machines in it's range? Thank you. Fajar.
