1 Business-Router-1-Lab.doc 1 CSCI 3342 If this lab is an Individual assignment, you must do all coded programs on your own. You may ask others for help on the language syntax, but you must organize and present your own logical solution to the problem. No lab is complete until the student submits the signed pledge form associated with that lab. I realize that no coded programs will be graded until I turn in the sign & pledge form associated with that program; any late penalties will continue to compound until the pledge form is submitted. If this lab is a team assignment, both team members may share logic as they program side by side on their own computers. Each person must type all of his/her own code as part of the learning process. Team assignments are never to be You do this portion and I ll do that portion or You do this lab and I ll do the next lab. Some of the lab assignments will have short answer questions. These short answer questions will be spot checked and graded for completion, but not checked for accuracy. Once these labs are graded and returned, I encourage you to form a study team comprised of members of this class who have also successfully completed this lab for credit; once the labs have been graded and returned, you may compare your answers with this team if and only if they have successfully completed the lab. I/We realize that the penalty for turning in work that is not my own, or assisting others in doing so, can range from an "F" in the class to dismissal from Trinity University. I realize that it is a violation of academic integrity to share any portion of this lab with any students (outside my prof & my 3342 study team)! Print Name Time Required =. Hrs.

Assume Router Has Been Reset To Factory Specifications For The Following 7] {T/F} You are about to connect to the Linksys router for the first time. You must install special software to connect to the Linksys Router. 8] When first connecting to a Linksys Router (or after a reset) with a browser, you connect the browser to IP address _?_. 9] {T/F} A Router IP Address, which becomes the intranet gateway, must always remain ] The local ip address of the router becomes the network gateway. The initial Local IP Address of the Linksys Router (or after a reset) is _?_. 11] {T/F} All routers use as the initial address. 12] Assume that the NIC card, above, is one of four computers connected to our router; it is set to A) To receive a an IP address from a router that issues DHCP addresses. B) To connect to our Linksys router with a static IP address. C) None of the above; it will not connect with to our router..

3 Business-Router-1-Lab.doc 3 CSCI ] If the card above already has an IP address issued from a different network, it might be necessary to bring up a command box and enter _?_ to release the IP, DNS, SUBNET, and GATEWAY associated with that other network. (This would be faster than restarting the computer) 14] If the card above has released the IP address, it might be necessary to bring up a command box and enter _?_ to acquire a new IP, DNS, SUBNET, and GATEWAY from our router. (This would be faster than restarting the computer) 15] How many DHCP hosts may connect to the router using the DHCP configuration above? 16] {T/F} The hosts, using the DHCP configuration above, may use wired or wireless connections. 17] The first IP address issued by the router configuration above would be _?_. 18] {T/F} Assume that router configuration above issues IP Address to one computer and another computer on the network has statically configured it s NIC card to use IP Address Both computers will be able to send and receive information, but it might be a bit slower. 19] What could we type in the command window to see our IP ADDRESS, GATEWAY, & SUBNET. 20] B Once we confirm that our NIC card has IP = 150, SUBNET = , GATEWAY = from the Linksys Router, we can connect to the router with the router by entering IP Address in a B_?_. 21] When first connecting to a Linksys Router (or after a reset) the default password is _?_ and the User Name is blank. 22] {T/F} In order to connect to the newly configured/initialized Linksys Router, the router must either be configured for DHCP or have a gateway of

B) To connect to our Linksys router with a static IP address. C) None of the above; it will not connect with to our router. 24] Assume that the NIC card, above, is one of four computers connected to our router; it is set to A) To receive a an IP address from a router that issues DHCP addresses. B) To connect to our Linksys router with a static IP address. C) None of the above; it will not connect with to our router. 25] {T/F} If the DHCP component of our router is not functioning properly, the network card configuration above might enable us to connect to the reset Linksys Router. 26] {T/F} Entering IPCONFIG /Release in the command line will free the IP Address associated with the card above. 27] {T/F} Routers can be configured to provide DNS entries passed on from the Internet Provider. (Hint True) If you manually assign these DNS entries on each of your wired desktops, you are setting up your network to be function when your ISP fails to provide DNS correctly!

5 Business-Router-1-Lab.doc 5 CSCI ] {T/F} Every network administrator should know one static IP address, outside his or her network, to ascertain whether the connection issues are for real or limited to DNS. (Carme is ). 29] {T/F} The reason that the network administrator should know one static IP Address outside his or her network, such as Carme = , is because PING requires DNS to function. 30] The newly configured/reset Internet Connection Type is A) Automatic - DHCP B) Static IP C) PPPoE 31] A snapshot, similar to the one above, may be found in the Linksys Router s _?_ tab. A) Setup B) Wireless C) Security D) Access Restrictions E) Applications & Gaming F) Administration G) Status

6 Business-Router-1-Lab.doc 6 CSCI 3342 Each operating system has some way to view the available wireless networks. The one above is an example from a windows 7 network. 32] {T/F} It is the Router Name, on the Basic Setup of the Setup Tab. that provides the Dr. Thomas Hicks seen in the wireless network connection list. 33] {T/F} It is the Wireless Router Name (SSID), on the Basic Wireless Settings of the Wireless Tab, that provides the Dr. Thomas Hicks seen in the wireless network connection list. 34] {T/F} The Internet Service Provider will generally provides a modem/router that enables you to connect to their service. For security purposes, Dr. Hicks always recommends that you place a router in between the ISP device and your computer(s). 35] {T/F} The router acts as a hardware firewall between the Internet and your computer(s). 36] {T/F} Some Internet Service Providers make will provide a single box that acts as both a router and a modem. This provides a hardware firewall between the Internet and your computer(s). 37] {T/F} You should always enable the software firewall on your laptop before connecting to a public network of any type. 38] {T/F} It is ok to connect a laptop to Trinity s public network without your firewall enabled.

A) Setup B) Wireless C) Security D) Access Restrictions E) Applications & Gaming F) Administration G) Status 40] One of the reasons that the IP Address, provided to the router by a Internet Service Provider via the cable modem, might be is because there is no C_?_ that properly connects the cable modem to your router. 41] {T/F} Some network providers, such as DSL, require that you use the provided UserName and Password in order to get an IP Adddress; this is generally done with a PPPoE Internet Connection. (Hint : T)

8 Business-Router-1-Lab.doc 8 CSCI ] {T/F} Some cable companies require that you use the provided UserName and Password in order to get an IP Adddress; this is generally done with a PPPoE Internet Connection. (Hint : T) 43] We have a cat 5 cable connecting our router to the ISP modem. One of the reasons that the IP Address, provided to the router by a Internet Service Provider via the cable modem, might be is because the U_?_ and P_?_ combination, required for PPPoE authentication, is incorrect. 44] The Router s IP Address is The required authentication, if any, is correct. The Cat-5 wires are connected properly. There is a button on the Status Tab that you might try pushing It is the _?_ button. 45] If the Router s IP Address is and (1) the required authentication, if any, is correct and (2) the wires are plugged incorrectly, and (3) you have tried pushing the DHCP button, then, Dr. Hicks would suggest trying disconnecting the power to the Modem and the Router; then turn on the _?_ and wait until it powers up properly and then turn on the _?_. 46] {T/F} Assume that the DHCP configuration, provided by your ISP, is shown above. The network administrator should make a written record of this configuration.

9 Business-Router-1-Lab.doc 9 CSCI ] Examine the DHCP configuration, provided by your ISP, above. Write the DNS entries that you should record on you re the basic setup of the Setup Tab. Static DNS 1: Static DNS 2: Static DNS 3: 48] {T/F} Should our modem fail to provide DNS information to our router, at some later date, our systems will be able to use the DNS entries provided by our router. 49] {T/F} We should use the DNS entries, written above, for both static and dynamic router configurations. Linking Your DNS Entry To Your Router- You Must Get A Registered Domain

10 Business-Router-1-Lab.doc 10 CSCI ] {T/F} There is only one place on the Internet where you can register a new domain; it is 123CheapDomains.com. 2] List at least one other place where you can register a domain. 3] {T/F} Suppose we would like to name our new company Trinity Networking Specialists and we would like the URL for that company to be TrinityNetworkingSpecialists.com. When I did the screen capture above, the URL was available, but I did not reserve it. Is it available now? NSLOOKUP 1] Bring up a command window. What could you enter to do a nslookup of SportsLifeSA.com. 2] If a web page were to go to SportsLifeSA.com, it would be going to IP Address _?_ 3] If a web page were to go to Yamax.com it would be going to IP Address _?_ 4] If a web page were to go to McLeanAudiology.com, it would be going to IP Address _?_ Static IPs Register Domain 1] {T/F} It is possible to host multiple web sites with a single static IP Address.. 2] {T/F} May Internet Service Providers will provide you, for an additional fee, a Static IP Address. 3] {T/F} Once you get your static IP Address, from your Internet Service Provider, you need to configure your URL to point to that IP Address.

11 Business-Router-1-Lab.doc 11 CSCI ] In the screen capture above, you can see where I configured HeightsCC.com at CheapDomains.com; it is associated with IP Address _?_ 5] {T/F} 123CheapDomains notifies the DNS Server Tree of changes made to my URL entry. 6] {T/F} Suppose DSL offered me more bandwidth for less money. They would provide me with a different static IP Address. I could use the 123CheapDomains form below to create a new IP Record which would replace my existing IP Record associates with ] {T/F} It would take minutes, to hours, for the DNS changes made at CheapDomains.com to dynamically cycle through the many Internet DNS Servers. I have decided to host HeightsCC.com in my home. You are the Network Specialist doing the configuration.
