Ip Address Essay

The Internet is a worldwide, publicly accessible series of interconnected computer networks that transmit data by packet switching using the standard Internet Protocol (IP).

When you type in a web address, e.g.www.google.com. DNS associates with the domain name, translates into IP address (for example 192.168.154.70 is the IP for google.com) and directs your Internet connection to the correct website.

IP stands for ‘Internet Protocol’ and is made of numbers and periods. It is the

Each IP that accesses the internet will be under a NAT protocol to help protect the users accessing the internet.

An Internet Protocol address is a numerical label given to each device participating in a network that uses the Internet Protocol for communication

1. The process of obtaining an IP address for a computer name (for example, “Computer A”) is called __________. Name Resolution

PC1 sending packet, first thing needing to be done is compare the destination IP address with its own, deciding whether or not it is in the same network

IP addresses can be used by more than one system, reducing the total number of IP addresses needed. This conservation of addresses is important because the Internet is quickly running out of IPv4 addresses. Although a particular IP address can be used by only one system at a time, many enduser systems require addresses only occasionally, when they connect to the Internet. By reusing IP addresses, DHCP lengthens the life of the IPv4 protocol. DHCP applies to IPv4 only, as IPv6 forces systems to configure their IP addresses automatically (called autoconfiguration) when they connect to a network (page 373).

Would the IP address in Figure 8-1 be valid as a class C address? Why or why not?

If you used the number of bytes instead you would get a whole different amount of possible networks which isn’t right.

2. How many bits are in an IPv4 IP address? In an IPv6 IP address?

The Internet is, quite literally, a network of networks. It is comprised of ten thousands of interconnected networks spanning the globe. The computers that form the Internet range from huge mainframes in research establishments to modest PCs in people's homes and offices. Despite the recent hype, the Internet is not a new phenomenon. Its roots lie in a collection of computers that were linked together in the 1970s to form the US Department of Defense's communications systems. Fearing the consequences of nuclear attack, there was no central computer holding vast amounts of data, rather the information was dispersed across thousands of machines. A set of rules, of protocols, known as TCP/IP was

The TCP/IP protocols are the heart and soul of the Internet, and they describe the fundamental rules that govern all communications in the network. The original address system of the Internet is Internet Protocol version 4 (IPv4). The Internet Engineering Task Force (IETF) developed IPv6 to deal with the long-anticipated problem of IPv4 address exhaustion. However, IPv6 is not foreseen to supplant IPv4 instantaneously.

IPv4 addressing is the next method, it’s is split up into two main parts as well Network I.D and Host I.D which are split over four octets which are written as four decimal numbers which have 32 bits, it only contains 4.3billion different IPs. For example, you sent an IP to a website and it sends its IP back, which means you can communicate. Whereas IPv6 addressing has 128 bits and is written as

What is IPv4? IPv4 is a 32-bit address used for communication between nodes using the TCP/IP protocol. The IPv4 address is broken into 4 octets each 8 bits long in binary and are broken into 5 different classes. Class A addresses start out where the first octet of the IP address ranged from 1-127 where 10 is reserved from private IP addresses. Class B addresses start out with 128 - 191 and has the 172.16.x.x to 172.31.x.x reserved from private IP addresses. Next is class C addresses that range from 192 - 223 in the first octet where 192.168.x.x is reserved from private IP addresses. Class D addresses range from 224 -239 in the first octet and are reserved from multicasting network traffic. Finally we have class E that range from 240 - 255 in the first octet and is reserved for experimental purposes ("IPv4," 2016).
