5. IP addresses in a local network The netmask also called subnet mask determines how many IP addresses belong to the local network The netmask is also a 32 bit address expressed in the same form as the IP address An example netmask is 255 255 255 0 This netmask has 8 zero bits in the least significant portion and this means that 9 addresses are a part of the local network Applied to the IP address above 216 103 126 155 this netmask would indicate that the following IP addresses belong to the local network 216 103 126 0 216 103 126 1 216 103 126 2 etc 216 103 126 254 216 103 126 255 The lowest and highest address are reserved for special purposes The lowest address 216 103 126 0 is used to identify the local network The highest address 216 103 126 255 is used as a broadcast address Usually one other address is used for the address of the gateway out of the network This leaves 256 3 253 available IP addresses for the example given Getting Started 31 4 4 How IP Addresses are Used The actual hardware connection via an Ethernet uses Ethernet adapter addresses also called MAC addresses These are 48 bit addresses and are unique for every Ethernet adapter manufactured In order to send a packet to another computer given the IP address of the other computer it is first determined if the packet needs to be sent directly to the other computer or to the gateway In either case there is an IP address on the lo
