The network design requires an IP schema that will minimize the cost of public IP addresses. Due to this requirement we will use a Class B IP address solution with a default subnet mask of 11111111.11111111.00000000.00000000 or 255.255.0.0. I am calculating the need to have 2 possibly 3 public IP addresses.…

Encapsulation is an attribute of object design. It means that all of the object's data is contained and hidden in the object and access to it restricted to members of that class. A procedure is a type of encapsulation because it combines a series of computer instructions. Likewise, a complex data type, such as a record or class, relies on encapsulation.…

The Internet Protocol (IP) sits in the middle of the five-layer TCP/IP model. IT provides service to the layers above it and receives services from the layers below it. Almost every computing device on the planet communicates in some way, and most of those use IP. IP exists as an Internet standard protocol, also called ipv4, although it is mostly just referred to as IP. IP was created in the 1970s, but did not reach standard status as the IPv4 RFC until the 1980s.…
CIDR moves way from the traditional IP classes (Class A, Class B, Class C, and so on). In CIDR , an IP network is represented by a prefix, which is an IP address and some indication of the length of the mask. Length means the number of left-most contiguous mask bits that are set to one. So network 172.16.0.0 255.255.0.0 can be represented as 172.16.0.0/16. CIDR also depicts a more hierarchical Internet architecture, where each domain takes its IP addresses from a higher level. This allows for the summarization of the domains to be done at the higher level. For example, if an ISP owns network 172.16.0.0/16, then the ISP can offer 172.16.1.0/24, 172.16.2.0/24, and so on to customers. Yet, when advertising to other providers, the ISP only needs to advertise 172.16.0.0/16.…

Working with Internet does not mean just browsing www and sending and receiving e-mails. The Basic Structure of the Internet was developed through last 30 years of existence of the Internet. The Internet is a heterogeneous worldwide network consisting of a large number of host computers and local area networks. The Internet uses the TCP/IP suite of protocols. This allows the integration of a large number of different computers into one single network with highly efficient communication between them. This way, the user can access information on all kinds of host computers from a desktop PC, Macintosh, or whatever he/she has available. TCP/IP, the communication standard underlying the Internet, originates from work done at the US-Department of Defense in the late 1960s. The first version of the Internet was built in 1969 and consisted of just four computers. In 1982 a set of specifications and protocols have been implemented, which became known as TCP/IP in reference to their two major elements, the "Transmission Control Protocol" and the "Internet Protocol". The development and implementation of TCP/IP stimulated a massive growth process for the Internet. "By late 1987 it was estimated that the growth had reached 15% per month and remained high for the following two years. By 1990, the connected Internet included over 3,000 active networks, over 3,000 active networks, and over 200,000 computers. By January 1992 the number of hosts on the Internet was 727,000, doubling about every 7 months. Various groups of users are connected to the Internet: universities and other educational institutions, government agencies, the military, and at an increasing number private businesses.…
