This study describes the different types of network configuration as well as data communication in the new private company based on software development. Company design is one headquarter and also two branches on the location in Brisbane, Australia. The headquarters network is a very secure network (307 + 701 = 1008). This network includes different types of devices and controls like computers, three servers, (7 + 1 = 8) printers, one router, and two switches. Network devices connected subsequently for two branches (7 + 70= 77) 0 and 51 that devices included to the one router and two servers and every branch have 8 switches. Another term for it is poor sub netting. In contrast to the system and broadcast, it was possible to prove that the sub must handle at least seven devices. As a result, these computations were carried out, and they employed the same subnet mask as well as an extra calculating based on the network address. When using a discussion thread, the original XY components indicated inside the assignment are kept, and modifications to the authorized Subnet Address of the IPv6 configuration are allowed. It is also intended that this section will feature one printer and one server.

### Address allocation plan for each subnet

2.1 IP addressing plan for IPV4

This part is defined as the allocation plane for IPv4 and IPv6. Apart from that, the mention is VLSM. This approach should be defined to the different subnet for IP addresses and that will be divided. When using a comment section, the original XY components indicated inside the assignment are kept, and modifications to the authorized Subnet Identity of the IPv6 config are permitted. It was also feasible to define that, in parallel to the network and broadcasting, the subnet must handle at least seven devices. It is also intended that this section will feature one printer and one server (Valdes-Garcia et al. 2019). This equipment included one network as well as two server farms, as well as light switches in each branch. This suggests that changes are only made after 64 bits since if changes are made inside 64 bits, the connection's identification would no longer become unique to only that relationship. As a consequence, these computations were carried out using the same subnet mask as well as an additional computation utilizing another subnet mask.

2.1.1 IPv4 allocation plan for Head Quarter

As previously stated, this company's IPv4 network address is 117.07.71.0. In addition, basic subnet criteria would be that the IP support network with at least 1008 connections. This parameter is necessary to establish the number of times bits would be stolen from the gateway ID to suit actual business needs (Kwark et al. 2019). It's also referred to as Low class subnetting, but it consists of breaking each subnet across smaller subnets. This network includes different types of devices and controls like computers, three servers, (7 + 1 = 8) printers, one router, and two switches. Network devices connected subsequently for two branches (7 + 70= 77) 0 and 51 that devices included to the one router and two servers and every branch have 8 switches.

### 2.1.2 IPv4 allocation plan for Branches (separate section for each branch)

Branch A now has seven devices, as per the information given. As a result of the identical methods employed inside the calculations again for Head Quarter, this was feasible to conclude also that the subnet must handle at least seven devices, along with the network plus broadcast. Furthermore, it is envisaged that somehow this section will feature one printer as well as one server. This network's smallest amount for this IPv4 became seven gadgets (Parida et al. 2019). However, as previously said, it really is expected that now the branch would grow significantly. As a result, that network could range to 64 addresses, somewhat like. As just a result, their subnet mask would be 26.

Branch B now has 70 devices, as per the information given. As a result of the identical methods employed inside the calculations again for Head Quarter, this was feasible to conclude also that the subnet must handle at least seven devices, along with the network plus broadcast. Furthermore, it is envisaged that somehow this section will feature one printer as well as one server (Martikainen et al. 2018). This network's smallest amount for this IPv4 became seven gadgets. However, as previously said, it really is expected that now the branch would grow significantly. As a result, that network could range to 64 addresses, somewhat like. As just a result, their subnet mask would be 26.

2.1.3 IPv4 allocation plan for router to router (separate section could be for each subnet)

These subnets interconnecting routers contain moment in time connections, and yet this particular organization has three subnets here between routers. Furthermore, several routers’ subnet masks must handle at least 4 gadgets. In addition, most routers don't even have a default gateway ip. As a result, the Ipv4 4 as well as 6 addresses was just as follows:

 Location Sub ID Sub mask CIDR Network Add IP Add (range) Broadcast Add R 1 0 1 117.11 7.117.170 /18 117.07.71 .0 117.07.22 5 -117.07. 71.4 117.07.227 R 2 0 2 117.117.1 17.170 /18 117.0 7.7 1.2 117.0 7.2 2 9 -1 17.07.71.0 117.07.231 R 3 0 3 117.1.117.170 /18 117.07.71. 1 117.07.23 3 - 11 7.07.71.34 117.0723 5

3.2 IP addressing plan for IPV6

3.2.1IPv6 allocation plan for Head Quarter

### 3.2.2 IPv6 allocation plan for Branches (separate section for each branch)

Branch A

 Location Sub ID CIDR Network add Default gateway add Key IP add IP add (range) B A 0 2 /48 1 0 4 5: B D 8:5 7 0 1::/48 1 0 4 5:B D 8:5 7 0 1: 3 F F F1::/48 10 4 5:B D 8:5 7 0 1::/48 to 1 0 4 5:B D 8 :5 7 0 1: 3 F F F 1::/48 1 0 4 5:B D 8 : 5 7 0 1: 3 F F F 1 ::/48 to 1 0 4 5 : B D 8:5 7 0 1 :: /48 B A 0 2 /60 1 0 4 5:B D 8:5 7 0 1::/60 1 0 4 5:B D 8:5 7 0 1:73F::/60 1 0 4 5:B D 8:5 7 0 1::/60 to 1 0 4 5:B D 8:5701:73 F::/60 1045:BD8:5 7 0 1:73F::/60 to 1 0 4 5:BD8:5701::/60

3.2.3 IPv6 allocation plan for router to router (separate section could be for eacg subnet)

 Location Sub ID CIDR Network Add Last IP R 1 0 1 /48 /60 1 0 4 5 : B D 8 : 5 7 0 1 ::/48 1 0 4 5 : B D 8 : 5 7 0 1 ::/60 1 0 4 5 : B D 8 : 5 7 0 1 ::/48 1 0 4 5 : B D 8 : 5 7 0 1 ::/60 R 2 0 2 /48 /60 1 0 4 5:B D 8:5 7 0 1: A 0 0 0::/48 1 0 4 5:B D 8: 5 7 0 1: 5 7 A 0::/60 1 0 4 5 : B D 8 : 5 7 0 1 : A 0 0 0 ::/48 1 0 4 5 : B D 8 : 5 7 0 1 : 5 7 A 0 ::/60 R 3 0 3 /48 /60 1 0 4 5:B D 8:5 7 0 1: 6 0 0 0 ::/48 1 0 4 5:B D 8:5 7 0 1:8 0 0 0 ::/60 1 0 4 5: B D 8 : 5 7 0 1: 6 0 0 0 ::/48 1 0 4 5 :B D 8 : 5 7 0 1 : 8 0 0 0 ::/60

Conclusions

This research discusses the many forms of network design as well as data transfer in a new software development-based private organization. The company is designed with one headquarters and two branches in Brisbane, Australia. Their Central office network is extremely secure. This network has several sorts of devices and controllers. This parameter is required to determine the number of times bits first from gateway ID might be stolen to meet actual business requirements. Impoverished sub netting is another name for it. It was also possible to establish that the subnet must manage at least seven devices, in addition to the network and broadcast. Furthermore, it is planned that this portion will have one printer and one server. This research successfully was done.
