ITC542 Internet Working With TCP/IP

Business.com has two branches that supply its services to the entire region; the business is located in the Western Sydney region. The headquarters comprises several devices that range from a printer, computer and among other devices that total up to 100 devices. There are 30 network devices in Branch A and then again branch B constitutes of 20 network devices. Due to the new room for IP addressing, the network devices need to be re-addressed, the details bellow stipulate how the re-addressing is to be performed (Baccelli, & Townsley, 2010).

IP allocations to devices and configurations will be done using the IP address 203.2.36.0 which is able to accommodate more addresses up to a maximum of 255 addresses that can be used (Xia, Wen, Foh, Niyato, & Xie, 2015).

The allocation of the IP address in the network will be as follows. The addresses will lay in the network   203.2.36.0 with the subnet mask as  255.255.255.0.The broadcast  address of the network in this case will be  203.2.36.255.The addresses for the host devices will lie between  address 203.2.36.1-203.2.36.254 with the default IP address as 203.2.36.1

This can be summarized as shown below

• network :    2.36.0
• subnet mask: 255.255.0
• broadcasting address: 203.2.36.255
• default gateway : 2.36.1
• IP range addresses: 203.2.36.1 – 203.2.36.254

The range (203.2.36.2 – 203.2.36.254) will be the IP address of which the devices will be connected to the headquarter network. Since the devices that are available at the headquarter are around 100  in number then this creates room for expansion of the network.

203.2.37.0 IP address configuration will be used to configure the devices in branch B, it will offer a sum of 254 IP address that is usable.  

• network address: 2.37.0
• broadcast address: 2.37.255
• default gateway  network address: 2.37.1
• subnet mask address: 255.255.0
• host address network range: 2.37.1 – 203.2.37.254

203.2.37.2 – 203.2.37.254 is the IP address range of which all the devices in the Branch B network will be connected to the network. This will create room for the network expansion.

The IP allocation procedure in this section uses IP bit 24 meaning that the maximum number of hosts in this section is 254.The network address of the network will be 203.2.38.0

• network address: 2.38.0
• sub netting mask: 255.255.0
• broadcasting address: 2.38.255
• default gateway address: 2.38.1
• host address range: 2.38.1 – 203.2.38.254

203.2.38.2 – 203.2.38.254 will be the IP address range in which all the devices in the Branch A network will be connected to it.

The above figure represents the diagram for the network in the business.com

The activities in this stage will be to recreate the network that was created in task 1. This will be done using class B network 163.36.0.0/16; which will be different from the class C network that was used on task 1. The following is a brief description of the users that are will be found in each department at headquarter (Bell, & Britton, 2009).

There will be 5 departments in the headquarter, the departments will include;

The sum of employees in the headquarter will be 18, 100employees will be at branch A and branch B will have 100 employees.

The functionalities of restructuring the Network in task one is to ensure that new devices such as VoIP will be incorporated to the network. It is also to ensure that the communication and security of the information is improved. This sections improves the functionality of the network due to addition of some additional features.

At the headquarter the network will be divided into 5 VLANs each department having its own vlan 163.36.0.0 is the network address to be used, to the five department. The following are the IP addresses that were assigned to each department in the network (Yalagandula & Mudigonda, 2012).

• Software VLAN0 163.36.1.1
• Customer VLAN1 163.36.2.1
• Solution VLAN2 163.36.3.1
• Finance VLAN3 163.36.4.1
• Sales        VLAN4 163.365.1

The following are the desired tasks that the re-engineered network is supposed to archive:

• Scalability an increase in the number of employees will need a large IP addresses, the network should be able to host all the IP addresses. In addition, the network should also accommodate extra cross-over cables that integrate the devices to the Vlans (Basak, Toshniwal, Maskalik, & Sequeira, 2010).
• VPN configuration on the switches will allow the resources from the company or home will be accessed easily.
• Shield cable will be deployed for the outdoor access network while the Ethernet cables will be used so as to elevate the performance of the network.
• The network should increase the security since the switches will be configured using an access denial protocol.
• Agility- this will be achieved if the network is done either by the use of cross-over cables and also enabling DHCP at each router.

There are 32 employees working in the department. 163.36.1.1/16 is the Vlan that will be used here.This is the address of the interface Vlan .It also acts as the default gateway of all the devices within this department (Liu, Andrews & Iyer, 2009).

The following is the order in which the IP addresses will be distributed:

• network address: 36.1.0
• subnet mask: 255.240.0
• broadcast address: 36.1.255
• default gateway address: 36.1.1
• host address range: 36.1.1 – 163.36.1.254

163.36.2.1/16 is the Vlan used where and the total employees where are 21.

The following is how the IP addresses are assigned:

• network address: 36.2.0
• subnet mask: 255.240.0
• broadcast address: 26.2.240
• default gateway address: 36.2.1
• host address range: 36.1.1 – 163.36.1.240

163.36.3.1/16 is the IP address for the  Vlan  that was used, where the department is made up of 15 employees.

The following is how the IP addresses are assigned:

• network address: 36.3.0
• subnet mask: 255.240.0
• broadcast address: 36.3.255
• default gateway address: 36.3.1
• host address range: 36.3.1 – 163.36.3.240

163.36.4.1/16 is the Vlan used where and the department is made up of 15 employees.

The following is how the IP addresses are assigned:

• network address: 36.4.0
• subnet mask: 255.240.0
• broadcast address: 36.4.255
• default gateway address: 36.4.1
• host address range: 36.4.1 – 163.36.4.254

163.36.5.1/16 is the Vlan used and the department comprises of 6 employees.

The following is how the IP addresses are assigned:

• network address: 36.5.0
• subnet mask: 255.240.0
• broadcast address: 36.5.255
• default gateway address: 36.5.1
• host address range: 36.5.1 – 163.36.5.240

The Local Area Network of the business.com company is depicted in the below logical network diagram.

163.36.0.0 Will be the IP address that used.

• network address: 36.0.0
• subnet mask: 255.240.0
• broadcast address: 36.255.20
• default gateway address: 36.1.1
• host address range: 36.0.1 – 163.36.255.254

163.36.0.1 – 163.36.255.254 will be the IP range of all the devices that will be connected to the Network.  

163.37.0.0 will be the IP addressed to used.

• network address: 37.0.0
• subnet mask: 255.240.0
• broadcast address: 37.255.255
• default gateway address: 37.0.1
• host address range: 37.0.1 – 163.37.255.254

In order to comprehend how the network will function, planning of the IP address in the network is necessary. In order for the information in the network to be secure, there are is need to put up security measures. There is also need to put up measures to ensure effectiveness of the network for communication purposes. This increases the ease to oversee and manage the network from a single node within the network.
