![]() ![]() In case of bridging, the IP address can be assigned to any interface in the bridge, but actually the address will belong to the bridge interface. Leaving a physical interface without an IP address is not a must when the bridging between interfaces is used. It is possible to add multiple IP addresses to an interface or to leave the interface without any addresses assigned to it. The network prefix and the broadcast address are calculated automatically. In most cases, it is enough to specify the address, the netmask, and the interface arguments. Itβs also possible to specify IP address followed by slash β/β and amount of bits assigned to a network mask. ![]() The network address value is calculated by binary AND operation from network mask and IP address values. For proper addressing the router also needs the network mask value, id est which bits of the complete IP address refer to the address of the host, and which β to the address of the network. Typical (IPv4) address consists of four octets. IP addresses serve for a general host identification purposes in IP networks. ![]()
