Lab Exercise 4 (Exploring TCP/IP Networks Part 1)

Objectives: We were to build an operational TCP/IP network using IPv4 addressing. We worked in groups to create two separate networks, then configured a router so the two networks could be connected to one another.

Equipment List: Multiple Computers, a router, two switches, multiple CAT5 cables

Notes and Observations: We did our work in a group of five. Three of us worked on the “B” Network and two of us (Nick and I) worked on the “C” Network. We created our own IP Addresses for each computer. Nick created a chart (BELOW) that we could look at in case we got stuck. I also made one simple typo that caused my computer to not connect to the network, and my instructor caught it.

Questions: What was the highest OSI layer the computers are currently connecting with? Layer 4

What protocol is used to automatically (dynamically) assign IP addresses to machines? DHCP (Dynamic Host Configuration Protocol)

How did you check connectivity? We pinged the other computers in our network

Can you think of other ways to confirm that the network works between the computers? The “tracert” (Trace Route) command should possibly work. Also maybe transferring a file via FTP to another computer on that network.

Conclusions: Our group was able to successfully connect our two networks together and ping eachother (after I fixed my typo).
