how to bind ip address and mac address / dhcp static ip configuration for dlink

Video is going to show you that how can bind ip and mac address in dhcp router configuration, when you changed your network to somewhere else and switch back to your this one, then sometimes different ip get assigned to you system, so to avoid that we bind ip to our system’s physical address i.e. mac address, so that we are telling the network(router) that assign this particular ip to my physical address of the system.
Thanks 🙂 .
