In order to be a class C address‚ it would have to be in the range of 192-223. 8.1.4 According to the subnet mask‚ what is the network ID of the IP address shown? What is the host ID? What is the binary network ID? What is the binary host ID? Does the IP address conform to the rules of classful networking? Why or why not? Network ID=190.8 Host ID=8

Application – Defines the applications used to process requests and what ports and sockets are used. I. (This layer is used to process requests from hosts and to make sure a connection is made to an appropriate port.) ii. Transport – Defines the type of connection established between hosts and how acknowledgements are sent. iii. Internet – Defines the protocols

host address in the access list statement‚ use the following formats: n.n.n.n n.n.n.n 0.0.0.0 OR host n.n.n.n Where n.n.n.n is the IP address of the host. To identify a network address‚ use the format: n.n.n.n w.w.w.w Where n.n.n.n is the subnet address and w.w.w.w is the wildcard mask. Enter access list statements in order‚ with the most restrictive statements at the top. Traffic is matched to access list statements in the order they appear in the list. If the traffic matches a statement

at one time because it was more common to use hubs. Before you subnet you need to sit down and figure out what needs to be subnetted; without planning and knowing exactly what you are doing you could cause more harm than good. When you are ready make sure that your subnet structure is the same as your network ’s geographic structure. When subnetting make sure that it is linked through a router and each subnet should have its own hub or switch. When you subnetting you need

Defines network and host portions of an IP address A 32-bit number in dotted decimal format‚ consisting of a string of eight or more binary 1s followed by a string of 0s‚ that determines which part of an IP address is the network ID and which part is the host ID. A binary 1 in the subnet mask signifies

addresses and their subnet masks are written as four octets‚ separated by periods‚ followed by a forward slash and a two-digit number that represents the subnet mask e.g. 10.1.1.0/30 172.16.1.16/28 192.168.1.32/27 etc . CIDR / VLSM Network Addressing Topology Example CIDR uses VLSM (Variable Lenght Subnet Masks) to allocate IP addresses to subnetworks according to need rather than class. VLSM allows for subnets to be further divided or subnetted into even smaller subnets. Simply‚ VLSM is

to ease network management. A well thought out network subnet design enables administrators to quickly locate computers by IP address by building floor and room‚ and whether the computer is a server‚ a student computer‚ staff computer or instructor’s computer. A proper subnet design will also minimize broadcast traffic that decreases network performance‚ by reducing the total number of computers allowed in each broadcast domain. A proper subnet design will also provide for efficient use of IP addresses

1.0/28 LAN Subnets Begin by creating and assigning the LAN subnets you will use. In order to make the most efficient use of your address space you should start by creating the subnet needed for the LAN with the most hosts and then work you down to the smallest LAN. Using the address space 10.1.16.0/21‚ create subnets for the LANs shown in the diagram and fill in the table 1 below. Notice that the first 7 subnets are all basically the same size and all subnets are all factors of 2 (remember
