Hello everyone I am playing with changing netmask for ip v4 address and find out that there is no other possibility to do it except:
ip address add 1.2.3.4/21 dev <device> ip address del 1.2.3.4/24 dev <device> Looks like all is working but I would like to get official answer that this is safe to do in such way? Look forward to your answer. Thanks in advance. -- All the best, Stanislav Makar
