subnetting and have actually learned subnetting concepts elsewhere. This white paper does not teach subnetting‚ it teaches useful methods for passing certification test questions. Overview of Subnetting The reason we subnet is to break larger IP networks into smaller ones. Often we have networks that are the same size. These use a fixed length subnet mask for all networks. Other network designs employ different subnet masks‚ depending on the number of addresses required for each subnet. This

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 file

The Internet Assigned Numbers Authority (IANA) controls numbers for protocols‚ the country code top level domains‚ and maintains the IP address allotments. IANA delegate allocations of IP address blocks to RIRs and administer the data in the root nameservers‚ which form the top hierarchical DNS tree.

A routable protocol operates at the Internetwork layer of TCP/IP. 4. Which of the following is a private IP address and can’t be routed across the Internet? The IP address 172.19.243.254 falls within one of the IP address ranges reserved for private uses by Internet standards groups. 5. Which TCP/IP model

consideration of the IP address’s class must be taken. Class A addresses have a default mask of 255.0.0.0; therefore‚ any 1s after the first octet will be considered subnet bits. The total number of network and subnet bits equal an address’s prefix. If a Class A address of 10.10.33.46 has a mask of 255.255.224.0‚ then all of the 1s in the binary form of that mask‚ which totals 19‚ would be the prefix. In CIDR notation‚ the address would be seen as 10.10.33.46/19. Dotted decimals IP Addresses are‚ for

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 209

Macomber” by Ernest Hemingway‚ a rich man with his wife on an African safari shows himself a coward when he runs from a wounded lion‚ to the disgust of both his safari guide‚ Robert Wilson and his wife. Hemingway uses imagery‚ representation and the narrative voice to reveal the importance of demands placed by heteronormative masculinity. Hemingway contrasts physical descriptions‚ weapons used and character perspectives to establish the identity of a masculine man. First‚ Hemingway‚ early in the
