Document Summary

Describe how computers and other devices are addressed on a network. Hosts o(cid:374) a (cid:374)et(cid:449)ork are assig(cid:374)ed host (cid:374)a(cid:373)es, (cid:449)hi(cid:272)h i(cid:374)(cid:272)lude the orga(cid:374)izatio(cid:374)"s do(cid:373)ai(cid:374) (cid:374)a(cid:373)e. Dns keeps track of which hosts name belongs to each ip address. Applications are assigned one or more port numbers to communicate with other applications. Ipv4 addresses have 32 bits and are written as four decimal numbers called octets. Ipv6 addresses have 128 bits and are written as eight blocks of hexadecimal numbers. Every nic on the globe is assigned a unique 48-bit mac address, which is frequently written as. The first part of the mac address is the 24-bit. The se(cid:272)o(cid:374)d part is the 24-bit device id, which is (cid:271)ased o(cid:374) the nic"s (cid:373)odel a(cid:374)d (cid:373)a(cid:374)ufa(cid:272)ture date. You can assign a static ip address to a computer or device, or you can configure a device to receive a dynamic ip address from a dhcp server each time the device connects to the network.
