If Microtik Company Add This Two Options This Would Be Great
I think it's more of device-centric issue, i.e. has to be done from the device which you want hidden. Otherwise, it's done via firewall rule as Jarda mentioned.this two options can decide who can see server ip and mac address from win box
usually equipment its managed from management networks not from user networksok
but my idea any neighbor routers can't be discovered if ip renge 254 ip
by this Two Options i can allow to 1 or 2 o 3 or 4 users to discover router from 250 users
