The internet that we use almost daily to complete some of our day to day activities actually is network of networks. It is a virtual world whereby all the computers on the internet are seen as to be in connection with every other computer on the internet. The internet is held together by the internet protocol (IP). It offers the best methods for transporting datagrams to the destination from the source regardless of the position of the networks in the machines whereby they may be located on the same network or other networks may be between the networks. The IP also routes packets of data between the networks and IP addresses. It also specifies the source and destination nodes’ location in the routing system topology. The IP address may be obtained automatically whereby the computer locates the DHCP server itself in the network and assigns it dynamically or it can also be assigned manually to the present interface of the network. It is divided into three entries, that is, the IP address assigned in the current interface of the network, subnet mask that is automatically done by the computer but can also be manually assigned and finally the default gateway which is used to connect a computer with the other networks.
This is what it entails in this report whereby we are going to plan the IP addressing of a biomedical software development company. The IP addresses will be assigned to the routers, printers, servers, computers among other end devices. We will also determine their subnet masks, broadcast addresses, network addresses and their specific IP addresses (Odom, 2013).
This biomedical company is located in Gold Coast. The company has two branches and the head quarter. The head quarter has 719 network devices, branch A has 71 network devices while branch B has 79 network devices. The branches are connected together using a LAN network that enables centralization of management since resources can be shared over the network. For example, while developing a software, different modules may be assigned to different individuals on the network and once a module has been completed, it is sent over the network to the person in charge of the whole software where they are combined to develop the full software. In case of printed materials that need to be shared in the network, they are efficiently sent over the network from the printers to the destination. The IT department configures all the networks using IPV4 and or IPV6 IP.
The following IPv4 IP address planning and allocation can be used for the biomedical software development company.
The head quarter has 719 devices that require to be assigned with the IP addresses of the IPV4. The IP address allocated for the head quarter is 191.2.71.0. This ip address is of Class B. Class B networks have a subnet mask of 255.255.0.0 but first we are going to get the number of networks which in this case is 64 networks. This is obtained by borrowing 6 bits from the host.
255.255.0.0 11111111 11111111 00000000 00000000, after borrowing the 6 bits, the following will be left: 11111111 11111111 11111100 00000000. From the binary number obtained, the subnet mask becomes, 255.255.252.0.
In this network, the following will be the plan:
The IP addresses will be assigned to the computers, printers and server among other devices (Lammle, 2011).
Branch A has 71 network devices. It will have an IP address of 172.16.10.2. One can allocate 510 hosts to allow for expansion in the future due to growth. The IP address also falls under Class B. The number of networks available in this network will be 128 as we are going to borrow 7 bits from the host. The remaining bits will be 9 bits in the host which will give us the 510 hosts (Cheshire, Aboba and Guttman, 2015).
255.255.0.0 11111111 11111111 00000000 00000000, after borrowing the 7 bits, the following will be left: 11111111 11111111 11111110 00000000. From the binary number obtained, the subnet mask becomes, 255.255.254.0
In this network, the following will be the plan:
Branch B has 79 network devices. It will have an IP address of 146.22.16.5. One can allocate 510 hosts to allow for expansion in the future due to growth just like in branch A. The IP address also falls under Class B. The number of networks available in this network will be 128 as we are going to borrow 7 bits from the host. The remaining bits will be 9 bits in the host which will give us the 510 hosts (Hain and Huston, 2015).
255.255.0.0 11111111 11111111 00000000 00000000, after borrowing the 7 bits, the following will be left: 11111111 11111111 11111110 00000000. From the binary number obtained, the subnet mask becomes, 255.255.254.0
In this network, the following will be the plan:
The following IPv6 IP address planning and allocation can be used for the biomedical software development company.
IPv6 allocation plan for Head Quarter
The head quarter has the IPV6 network of 2001:1234:ABCD:7100::/56. 56 bits has 256 networks which accommodates up to trillions of IP addresses. In this address, the first three sections represent the global routing prefix, that is, 2001:1234:ABCD:, while :7100:, represents the subnet id and finally :: section represents the interface identifier. So, while subnetting the IPV6, we will focus on 7100 (Hinden and Deering, 2016).
Therefore, the plan for the subnetting will be as follows:
2001:1234:abcd:71ff:ffff:ffff:ffff:ffff
Branch has the IPV6 network of 2001:DB8:1:2F00::/56. It has 256 networks which accommodates up to trillions of IP addresses. In this address, the first three sections represent the global routing prefix, that is, 2001: DB8:1: 2F00:, while :2F00:, represents the subnet id and finally :: section represents the interface identifier. So, while subnetting the IPV6, we will focus on 2F00 (Hinden and Deering, 2013)
The plan for the subnetting will be as follows:
2001:db8:0001:2fff:ffff:ffff:ffff:ffff
Branch B has the IPV6 network of 2000:ACAD:1234:6600::/56. It has 256 networks which accommodates up to trillions of IP addresses. In this address, the first three sections represent the global routing prefix, that is, 2000:ACAD:1234:, while :6600:, represents the subnet id and finally :: section represents the interface identifier. So, while subnetting the IPV6, we will focus on 6600 (Wegner, Rockell and Brandon, 2010).
The plan for the subnetting will be as follows:
The diagram below represents the logical network diagram for the biomedical software development company. The physical network diagram is included in Appendix A.
Conclusion
From the report discussed above, it’s clearly observed that IP addressing is a very important aspect in every organization utilizing networking. This is because it enables smooth communication between different and connected devices and departments thus enabling smooth running of the organizations’ activities. Therefore, when it comes to IP addressing, the administration should be very careful while assigning the IP addresses to various network devices.
