Here is my answer to Task 1: Subnet Number | Network Address | Usable Host Address Range | Broadcast Address 1 | 172.16.10.0/27 | 172.16.10.1 - 172.16.10.30 | 172.16.10.31 2 | 172.16.10.32/27 | 172.16.10.33 - 172.16.10.62 | 172.16.10.63 3 | 172.16.10.64/27 | 172.16.10.65 - 172.16.10.94 | 172.16.10.95 4 | 172.16.10.96/27 | 172.16.10.97 - 172.16.10.126 | 172.16.10.127 5 | 172.16.10.128/27 | 172.16.10.129 - 172.16.10.158 | 172.16.10.159 6 | 172.16.10.160/27 | 172.16.10.161 - 172.16.10.190 | 172.16.10.191 7 | 172.16.10.192/27 | 172.16.10.193 - 172.16.10.222 | 172.16.10.223 8 | 172.16.10.224/27 | 172.16.10.225 - 172.16.10.254 | 172.16.10.255 2) The new subnet mask is /27 ==> 255.255.255.224 3) 30 Hosts for per subnet

Step 1
For the R3 interface connected to the Office3 network, we assign the first usable IP address of subnet 1, which is 172.16.10.1, and the subnet mask is 255.255.255.224 (/27). Show more…

Activity 2: Who would assign an IP address when your computer connects to the network? This is the role of DHCP. First, we are going to do a small role play to mimic DHCP. Each member of the group has a role to play. Assume your group is your local area network (LAN). For example, you could consider a LAN at your home or at our campus or at your workplace. 1. One group member can act as a router with a DHCP server and other three members can act as host devices that try to connect to the network. These host devices could be PCs, printers, and network storage devices. A sample network that you are trying to mimic is shown in the below figure. 2. Assume that all the devices are physical connected as shown in the above figure. Now, your job is to set up the network and establish the connections with the router using DHCP. Each member needs to send/ respond with the correct message following the correct message sequence to establish the connections and to receive an IP address for each host/device. 3. Draw a timing diagram to indicate the sequence of messages that transferred between devices. 4. Next, we are going to implement a DHCP server in Cisco packet tracer and check the DHCP in action. Make sure to take screenshots of the networks you build, analyses, and verifications. Open the packet tracer and implement the following network. You may need to use the same model of the devices shown in the diagram. Today, we are not going to use static IP configuration for the hosts as we are going to check functionalities of DHCP. If you have not watched the video available in Section 5.6 (in Module 5) which provides an overview on how to configure DHCP server in Cisco Packet Tracer, please watch the video before you start the task. Tips: You need to add a module with a fast ethernet port to the router, so that the router can support three LANs as shown in the below network diagram. a. Set up the DHCP server by configuring the network pools, default gateway, and IP address (use the subnets mentioned in the diagram). b. Set up the router by configuring the interfaces and DHCP (use the subnets mentioned in the diagram). c. Set up each host with DHCP to obtain IP configuration and verify the IP address and the default gateway. d. Verify the connectivity between each host in the network.

Subnetting a Network Using the C/IDR Method Worksheet 1 When completing this worksheet, make sure to change your font color to red or 5 points will be deducted. This worksheet is worth 300 points (100 pts per table). 3. Host IP Address: 192.168.21.83 Five bits have been borrowed to create the required subnets. What default class is this address? A, B, or C? What is the default subnet mask? What is the subnet mask for this host AFTER the bits are borrowed? How many subnets were created? How many actual hosts per subnet? How many usable hosts per subnet? Perform the ANDing process on the supplied host address (Remember, the process must be done in binary format or it will be marked wrong) Address Subnet Mask Result What is the network address for the supplied host address? (The Network address is the result from the above step, but it should be answered in Dotted Decimal Format, or it will be marked wrong.) What is the broadcast address for the supplied host address? Is the address 192.168.21.70 a Network, Host or Broadcast address? Is the address 192.168.21.135 a Network, Host or Broadcast address? Is the address 192.168.21.72 a Network, Host or Broadcast address? Is the address 192.168.21.167 a Network, Host or Broadcast address?

Lab Task 1: Design an IP Address Scheme Devise a network topology plan for the number of subnets you will need and where you want to assign the IPv4 addresses within each subnet. 1. Divide the 172.16.10.0/24 network into eight subnets. Fill out the Addressing Table below: Table 1: Addressing Table Subnet Number | Network Address | Usable Host Address Range | Broadcast Address --------------|-----------------|--------------------------|------------------ 1 | | | 2 | | | 3 | | | 4 | | | 5 | | | 6 | | | 7 | | | 8 | | | 2. What is the value of the new subnet mask? 3. How many usable host addresses exist per subnet?
