LAB 6 : TCP/IP UTILITIES

Exercise 1: Host IP configuration

 

Open a command prompt window and type:

>ipconfig/all

 

 

 

Table 1: IPCONFIG UTILITY

	Your host
MAC address	30-F7-72-3A-06-F1
IP address	10.8.214.58
Subnet Mask	255.255.252.0
Default Gateway IP address	10.8.215.254

 

 

 

 

Exercise 2: Network configuration and connection status

 

On a command prompt type:

>ping ip address or hostname

 

1. Ping your own host

 
2. Ping your neighbor on the same subnet 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

3. Ping one host on a different subnet

 

 

 

 

 

 

 

 

 

 

 

 

 

 

4. Ping a host that is shut down (20.20.20.20)

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Table 2 : Ping

Instruction	Sent	Received	Lost	Round trip times (Min)	Round trip times (Max)	Round trip times (Average)
1)	4	4	0 (0% loss)	0ms	0ms	0ms
2)	4	4	0 (0% loss)	2ms	8ms	5ms
3)	4	0	4(100% loss)	No result	No result	No result
4)	4	0	4 (100% loss)	No result	No result	No result

 

 

 

 

Exercise 3: Domain Name System (DNS)

 

Determine the local hostname of your machine by typing the following:

>hostname

 

Write down your local hostname here: Janapiriya10

 

 

You can run nslookup in interactive mode by typing:

>nslookup

 

 

 

 

 Table 3 : nslookup table

DNS server name	Address
ns5.uthm.edu.my	192.168.240.101

 

 

 

Question:

What do you understand from this laboratory exercise? Please explain your experience in a blog with your friends (your usual friends during lab session.

> From this lab exercise, I had learned about ping command which can be use to test the availability of a networking device (usually a computer) on a network. I learned how to ping the IP address or a hostname. Furthermore, I had understood that the ipconfig command displays all current TCP/IP network configuration values and give basic information such as IP address, DHCP Server IP address, subnet mask and more. Other than that, I had learned about nslookup command. It is a tool included in many operating systems that can look up IP addresses and perform other searches on DNS domains and servers.
