Network And Network Address Translation

In this scenario I will be providing information associated with the creation of a WAN for ACME Manufacturing. This business has several locations spread out all over America and requires a WAN to connect their locations in America with their newly build plant in China. With the headquarters and engineering offices in Atlanta, which are right across the street from each other, the plan would make sense to connect all communication here. There are also distribution offices in New York, Chicago, and Phoenix which will have to be connected to this network to attend the weekly company meetings and have access to information

VPN refers to the networking technology Virtual Private Network. A VPN allows users connected to this network the ability to access any website or computer data from any location in the world with dedicated and secure networking environment rather than being present in a public server. Majority of VPN users belong to business class industry and educational purposes. VPN networks are used in this manner because majority of VPN networks offer the features like encryption and anonymity which increases the privacy and security benefits while using the VPN network. VPN networks also allow the user ability to perform activities on the internet as if they were accessing

Remember the internet works with ACL or access control list, allowing for the possible for a person to reach Google without being a part of the same subnet. There is a common method UDP host punching. UDP hole punching is a commonly used technique employed in network address translator (NAT) applications for maintaining User Datagram Protocol (UDP) packet streams that traverse the NAT. NAT traversal techniques are typically required for client-to-client networking applications on the Internet involving hosts connected in private networks, especially in peer-to-peer, Direct Client-to-Client (DCC) and Voice over Internet Protocol (VoIP) deployments. UDP hole punching establishes connectivity between two hosts communicating across one or more network address translators. Typically, an application, when it sets up direct communications between two or more communicating hosts choosing to use a third-party host on the public transit network by using a UDP port. Usually normal communications traffic or when there is no significant traffic keep-alive packet traffic usually consisting of empty UDP packets ore packets with minimal non-intrusive content enable once port state keep the port states open. A common example of programs which use UDP hole punching consist of Team

classless interdomain routing (CIDR)- One of the short-term solutions to the IPv4 address exhaustion problem that actually helped solve the problem for a much longer time frame. CIDR allows more flexibility in how many addresses IANA assigns to a

For example the way a Router communicates to a computer is through an IP address which is assigned by the router which will then find the computer and transmit information to and from the computer.

Subnetting involves borrowing host bits from an ip address to create multiple IP addresses that can either be used or saved for future workstations. This mechanism also allows an organisation to divide its network into groups which can represent departments in an organisation (i.e. Financial department), this also ensures that only the workstations within the subnetwork can access the network resources given to that department making the network more secure by restricting other departments who are not authorized to view or deal with the data

During this period, the network identifies the product and assigns the IP address or hostname of the product.

7. Describe the difference between public and private IP addresses. If a network is using

To outface this problem Network Address Translation (NAT) method is used. This enables devices with private addresses to be connected to a public network address (e.g. Internet). This private address is converted to legal IP address, through NAT routers before traveling 11 “outside”. (See figure 4). Every device that is connected to the network has a unique IP address but this doesn’t mean that is permanent. Because devices connected to the network,

VPN configurations will be used between each location to ensure site-to-site connectivity. The VPN will allow employees to access the company's intranet from home or while traveling outside the office, and site-to-site VPNs allow employees in geographically disparate offices to share one cohesive virtual network. A VPN can also be used to interconnect two similar networks over a dissimilar middle network; for example, two IPv6 networks over an IPv4 network.[6] which will

so it asks IANA or an associated RIR to assign the company some public IP addresses. Which of

“Virtual private Network” transfer info by encapsulating traffic in IP packs and sending the packets over the internet. Companies that use a VPN from an ISP have outsourced their networks

Static IP address is an IP address that is permanent to a specific host for a certain amount of time. This IP address is assigned by the ISP out of a specific designated block of IP addresses and manually entered into the computer. While primarily IP addresses are sent to the host by the DHCP now, certain people prefer static IP.

In order to properly address the Infrastructure upgrade of the Kamazon Network our group decided that an appropriate ip address schema that will take into account the idea that people will be using more than just a desktop computer. They will have tablets, laptops, departmental printers, and smart phones. This is also based upon the understanding that every Department will have at least two printers for the staff and one for the Manager/Supervisor or VP of that Department. So with that being said, we estimated that could be at least three or more accurately four ip addresses per employee. So we multiplied the number of users per department by the number of estimated devices that each

Restricting the disclosure of internal or private IP addresses is essential to prevent a hacker “learning” the IP addresses of the internal network, and using that information to access the network. Methods used to meet the intent of this requirement may vary depending on the specific
