IP address Essays & Research Papers

IP-Subnet-Mask numbers IP mask numbers are used to divide internet addresses into blocks called subnets. The mask number represents the number of 1s in the binary of the address that is 'masked" against the address so that it ignores the last bits which are for the group of IP addresses in the masked address. The first address of a subnet block (all 0s) is called the network address or network ID. The last address (all 1s) is the broadcast address of the network. Typically the network...

A crash course in TCP/IP At first glance, TCP/IP (Transmission Control Protocol/Internet Protocol) may seem baffling. Many other protocols, such as NetBEUI and IPX/SPX, require no configuration. TCP/IP is different. Due to the seemingly endless number of options that you can configure within TCP/IP, many people become intimidated at first. In reality, however, TCP/IP isn't very difficult, but you have to gain some understanding of what you're configuring. So, I'm going to give you a crash...

An Internet Protocol address is a numerical label assigned to each device participating in a computer network that uses the Internet Protocol for communication. An IP address serves two principal functions: host or network interface identification and location addressing. Its role has been characterized as follows: "A name indicates what we seek. An address indicates where it is. A route indicates how to get there." The designers of the Internet Protocol defined an IP address as a 32-bit number...

The company that I am working for has been expanding and thusly has more equipment and personnel. We traditionally use static IP addressing but this is no longer sufficient. It is now time that we start using DHCP due to the fact that this will allow better functionality through the automatic addressing and leasing of IP addresses. More benefits of using DHCP are the massive amount of IP addresses that are available in DHCP and the fact that DHCP will automatically recall an IP address once the...

IP addresses consist of numbers that are 32 bits long (in binary), have 4 octets (bits of 8) and use the decimal dot notation. IP addresses are comprised of two components: the network ID and the host ID. For example: In a class C network: 192.168.10.128 Network ID Host ID (16-bit block) (8-bit block) DNS (domain name system) is used with IP addresses. DNS converts domain names and websites to IP addresses, which a computer can read. The computer remembers the IP...

When connecting to a network the process of finding the IP address is what ultimately allows you to connect. Now creating a router to router connection you are going to want your IP addresses to stay the same. Basically the difference in a static IP and a dynamic IP is that one IP stays the same and the other changes based off of a time limit. A static IP will always remain the same address. A dynamic IP will constantly change. This is beneficial because it slows attempts at unauthorized...

Unlike some network layer protocols, TCP/IP is specifically designed to facilitate the routing of info over...

IP Addressing Scenario According to the scenario, the company will have a single, physical location with approximately145 hosts on the network. In this case, I would suggest using a class C address such as 192.168.0.0. Reason why is because you can put all the devices on a single subnet with the subnet mask 255.255.255.0/24. This would allow for 253 usable host addresses, which is more than needed in this case. Whether you should dynamically or statically assign those IP’s goes, I...

Transmission Control Protocol (TCP) and Internet Protocol (IP) are the two main protocols that the internet uses. A protocol is a rule that governs how data moves through the internet and how network connections are established and terminated. TCP/IP, as it is commonly called addresses separate issues that allow the use of the internet. They complement each other. TCP is in control of accurate delivery of a message. How does this happen? First it controls the disassembly of the message or...

TCP/IP LAN Check Point #8 Answer: C Explanation: The network address 150.50.0.0 that was originally assigned is a class B, so it has a default subnet mask of 255.255.0.0. Then you need to divide this network into 7 subnets and only the net work address 255.255.240.0 provides enough networks because it will provide 16 - 2 = 14 subnets (-1 for the network address and -1 for the broadcast address, which gives a -2 from the total of subnets). #9 Answer: C Explanation: The network address...

Chapter 12 makeup IP routing, Static and connected routes IP routing defines how an IP packet can be delivered from the host at which the packet is created to the destination host. Hosts and routers participate in the IP routing process. The list summarizes a host’s logic when forwarding a packet, assuming that the host is on an Ethernet / wireless LAN. When sending a packet, compare the destination IP address of the packet to the sending host’s perception of the range of addresses in the...
