The inform mation will be used in n the following g parts of this s lab with pac cket analysis. Rec cord this infor mation in the table provide ed. P Part 1: Record R a PC’s IP Configura C ation Info ormation In Part 1, you will use the t ipconfig /all / command d on your loca al PC to find a and record the e MAC and IP P addresses s of your PC’s s network inte erface card (N NIC), the IP a ddress of the e specified default gatewayy, and the DNS serv ver IP address s specified forr the PC. R Required Resources R 1 PC (Win ndows 7, Vista, or XP with a command prompt accesss, Internet acccess, and W Wireshark insta alled) This lab asssumes that yo ou have Interrnet access. Note: This s lab cannot be b completed d using Netlab b. You Y will use Wireshark W to examine e the DNS query a nd response exchanges w with the name server. In this lab b, you will com mmunicate witth a DNS serv ver by sendin ng a DNS que ery using the U UDP transporrt protocol. DNS querries and respo onses are verry small and do d not require e the overhea ad of TCP.

p UDP P is connectio onless and do es not require e a session setup as does TCP. Your PC’s s DNS server query and th he DNS serve er’s response make use of the User Dattagram Protoccol (UDP) as the transport layer protocol. When you type a website UR RL into your brrowser, your PC P performs a DNS queryy to the DNS sserver’s IP ad ddress. DN NS is a distrib buted network of o servers thatt translates us ser-friendly do omain namess like to a an IP addresss.
