Name: Anthony Bonanni Section Number: 12 Internet Scavenger Hunt Lab Format: email finished worksheet to your instructor BACKGROUND Read an introductory tutorial at the following website, http://www.w3schools.com/tcpip/tcpip_intro.asp which also explains in more detail the concept of T ransmission C ontrol P rotocol/ I nternet P rotocol known as TCP/IP . The Internet is based on the TCP /IP protocol. This protocol allows all different types of networks to communicate with one another using the same language or standard. All hosts using the Internet have registered IP addresses. This number consists of two parts, a network ID and a host ID. Internet Protocol version 4 otherwise known as IPV4 consists of 4 bytes or 32 bits. (There is a newer protocol called IPV6 which consists of 128 bits for an IP address.) For example, Temple University website IP address is 155.247.166.60 . Each of the four sections represents an octet, 1 byte or 8 bits. Each octet has a value from 0-255 or 256 unique values of 0, 1. Part of the IP address identifies the network as the Temple network, and part of the IP address identifies the actual computer on the Temple network. 155.247.166 is the Temple network address. The 60 identifies the individual or host computer on which the Temple website is located. The IP address has to have the network portion so the routers can send the packets to the proper network. The router sees the 155.247.166 as 10011011.11110111.10100110 as the network address. The router uses built in algorithms to discover the possible routes and then selects the best route to send the packets from one network to another. Once the packets arrive at the right network, it is sent to the correct host which is indicated by the number 60 or 00111100 . All Internet communications including emails, IMs, audio and video downloads require IP addressing to connect. The Domain Name System or DNS translates the IP address and Domain Names . For more detail, visit the following Web site, http://computer.howstuffworks.com/dns.htm The Domain Name refers to the text name of the Web site. Each name must be unique. There are specially designated computers which hold tables which maps IP addresses to website domain names. Without the DNS system, one would have to know all the IP addresses of the websites you wanted to visit. Some examples of domain names include microsoft.com, and temple.edu. ACTIVITY
