Lab Sheet 5- TCP/IP
1. How to check our computer IP
address? Give me several ways on how to do it.
Method 1- Finding the internal IP
address using Command Prompt
1. From the desktop,
navigate through; Start
> Run> type "cmd.exe".
A command prompt window
will appear.
2. At the prompt, type
"ipconfig /all". All IP information
for all network adapters in use
by Windows will be displayed.
3. Using the search bar can reduce
the search time of the keyword “IPv4”
4.
The internal IP address is found
Method 2 - Finding the internal IP
address by viewing the network connection details.
1. Right click on the “Wi-Fi” icon below.
2. Choose the “Network & Internet Settings” option.
3. Click on “Change
adapter options”.
4 Right-click on Wi-Fi or Local Area Connection and
click “Status”.
5.
Select “Details...”
6.
The internal IP address is found.
Method 3 - Finding the external IP
address
1.
Go to the website https://tools.keycdn.com/geo.
The external IP address is found.
Method 4 - Finding the external IP
address
1.
Google “my ip”
2.
The external IP address is found
2. How are we going to setup
static IP configuration?
1. Right-click on the “Wi-Fi” icon below.
2. Choose the “Network & Internet Settings” option.
3. Select the “Change adapter options”
4. Right-click on Wi-Fi or Local Area
Connection. Click Properties.
5.
Double click “Internet Protocol
Version 4 (TCP/IPv4)”
6.
Choose the “Use the following IP address”
7.
Enter the IP address, Subnet mask, Default gateway, and DNS server that the user prefers. Click
“ok” to apply the settings.
3.
When do we need to setup static
IP configuration?
Set up and manage DNS server.
Static IP the configuration provides better DNS support: Static IP addresses are much easier
to set up and manage with DNS servers.
Server hosting: If we are hosting a web
server, email server, or any other kind of server, having a static IP address
makes it easier for customers to find us via DNS. Practically speaking that
means it's quicker for clients to get to our websites and services if they have
a static IP address.
Making remote access: A static IP address makes it easier to work
remotely using a Virtual Private Network (VPN) or other remote access programs.
Establishing communication: Static IP addresses make it easier to use
Voice over Internet Protocol (VoIP) for teleconferencing or other voice and
video communications.
4. Do you know the type of UTHM IP configuration? Is it static or dynamic?
”DHCP Enabled” is YES which means UTHM Wi-Fi
have a dynamic IP address.
5. What is static IP ?
An Internet
Protocol (IP) address is a unique number assigned to each
computer on a network. Just as a street address determines where a letter
should be delivered, an IP address identifies computers on the Internet. If our
computer is hosting a web server, its IP address is what identifies it to the
rest of the Internet.
A
computer on the Internet can have a static IP address, which means it stays the
same over time, or a dynamic IP address, which means the address can change
overtime.
6. What is
dynamic IP? When do we need to use dynamic IP? When do we need to use dynamic
IP?
A dynamic IP address is an IP address that an ISP lets you
use temporarily. If a dynamic address is not in use, it can be automatically
assigned to a different device. Dynamic IP addresses are assigned using either
DHCP or PPPoE.
We use dynamic addresses because IPv4 does not provide
enough static IP addresses to go around. Therefore, for example, a hotel
probably has a static IP address, but each individual device within its rooms
would have a dynamic IP address.
On the internet, our home or office may be assigned a
dynamic IP address by our ISP's DHCP server. Within our home or business
network, the dynamic IP address for our devices -- whether they are personal
computers, smartphones, streaming media devices, tablet, what have you -- are
probably assigned by our network router. Dynamic IP is the standard used by and
for consumer equipment.
7.
By using two IP addresses, show me how to configure a simple network (Consist
of Computer A and
Computer B). Show me step
by step.
Repeat the steps in Question 1- Method 1 to
reach IPv4 Properties. Set the IP address and default gateway like so.
1. Right-click on the “Wi-Fi” icon below.
2. Choose the “Network & Internet Settings” option.
3. Select “Sharing Options”
4. Under the “Private” Tab, check the options like so.
5.
Under the “Guest or Public (current profile)” Tab, check the options like so.
6.
Under the “All Network” Tab, check the options like so.
7.
Create a file that you want to share with another computer. In this case, a
file named “Testing sharing folder” is created at desktop. Right click and
select “properties”.
8.
Under the “Sharing” tab, click on “Share...”
9.
Select “Everyone” and click “add” to allow everyone to access to the file.
10.
Give the permission level of the “Everyone” to able to read or write.
11.
Click “done”.
12.
Click on “Advanced Sharing... ”
13.
Check the “Share this folder” option.
14.
Now, change the IPv4 settings in computer B like so. Notice that the IP address
and default gateway is different with Computer A.
14.
Right-click on the Wi-Fi icon and click “Open Network & Internet Settings”
15.
Click on the “Sharing options”.
16.
Check the “Turn on network discovery” option under the “Private” tab in
Computer B.
17.
If everything is working fine, a notification will pop out and ask if the user wants
to connect to the network. Click “Yes”.
18.
Computer A will able to access the files that computer B shared on the network.
It goes the same with computer B.
19.
Here is an example of files that can be accessed on another computer.
20. The folder “testing shared files” on the network.
