The hardware address is used to forward packets within a physical network. 2) The logical or Internet address is used to facilitate moving data between physical networks. The 32-bit Internet address is made up of a network number, a subnetwork number, and a host number. Each host computer on the Internet has a unique address. All Internet addresses at SLAC have a network number of 134.79. All Internet hosts have a numeric address and an English- style name. For example, the Internet address for SLAC's IBM 3480 is 134.79.17.41. Its Internet name is SLAC.Stanford.EDU.
