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

Unit 7: Internetworking Using TCP/IP: Part 2 Abstract IP uses the Address Resolution Protocol‚ ARP‚ to bind a next-hop IP address to an equivalent MAC address. ARP defines the format of messages that computers exchange to resolve an address‚ the encapsulation‚ and the rules for handling ARP messages. The NAT mechanism allows a site to have multiple computers using the Internet through a single IP address. The User Datagram Protocol provides end-to-end message transport from an application

NYEDGE2 and NYWAN1 connect to NYEDGE1 through serial connections. Each router has a locally attached Ethernet network. The serial line data rates and DTE/DCE settings have already been configured on all three routers. You only need to assign the IP address to the interfaces. Notes The routers are connected directly to each other in this lab and do not actually connect through any leased line services.
