In IPv4, IP addresses that start with decimal 127 or that has 01111111 in the first octet are loopback addresses(127.X.X.X). Local Loopback Address is used to let a system send a message to itself to make sure that TCP/IP stack is installed correctly on the machine. The host sends a broadcast to the broadcast address to request an IP address and in turn the DHCP server allocates an IP address from the pool of IP addresses.īy default, local broadcast address is always dropped by routers and layer 3 switches but one can always override this by configuring the device with DHCP forwarding or DHCP relay. It is represented by 255.255.255.255 or 11111111.11111111.11111111.11111111 in binary.Ī broadcast address is used by hosts to request IP addresses from the DHCP(Dynamic Host Configuration Protocol) server. Local Broadcast Address is used to communicate with all the devices on a local network.
