...Arthur Raynes Boakai NT 2640 IP Addresses Classes and Special-Use IP Address space September 26, 2013 IP Address Class: Class A: class A addresses are assigned to networks with a very large number of hosts. The high-order bit in a class A address is always set to zero. Class A permit up to 126 networks by using the first octet of the address for the network identification. Class B: class B address is designated for mid-sized corporations and ISPs. They allow 16, 384 networks by using the first two octets of the address for network identification. The first two bits of the first octet are fixed to 1.0. Class C: is designated for small offices and home offices. They allow for approximately 2 million networks by using the first three octets of the address for network identification. The three bits are fixed to 1 1 0. Class D: were reserved for multicasting purposes. The addresses begin with an octet in the 224-239 range. RFC 1918 IP addresses are used for private networks without concern for potential addressing conflicts with other networks. It has specify ranges of IP address that can never be routable on the global internet. RFC 1918 IP address ranges: 10.0.0.0 - 10.255.255.255 172.16.0.0 - 172.31.255.255 192.168.0.0 - 192.168.255.255 Special-Use IP Address...

...Stacie Rollins Thursday, January 8, 2015 NT 2640 Unit 1 Assignment 1 Network IDs used to be divided into classes, which were Class A, B, and C. These classes were allowed to have a range of addresses. This class-based system would work well for a while, but the rapid growth of the Internet it becomes evident that this addressing scheme had to be changed in order to support the many networks that were being created. A class full system would be created and still used the IP addressing fundament of a classless system. This 32-bit IP addressing system is subdivided into two portions; the network address space are the host address space. Class A addresses were created for a very large network with few logical network segments and many hosts that have the high-order bit set to zero. The first octet is used to define the network ID. Class A address cannot be greater than 127 because a value of 128 would require the left-most bit be set to 1. Class B addresses always have the first two high-order bits that are set to 10 and are used for medium-sized networks that have a moderate number of hosts connected to them. The Class B network ID, will utilize the first two octets for the network ID, which allows more network IDs and fewer hosts than a Class A network, because it uses an additional octet for the network. Class C addresses are for small networks with few hosts. These addresses have the first three high-order bits set to 110, because Class C addresses use the first three...

Bellman – Ford | Dual algorithm could be in status, query out the whole network shortest path. | Protocol | USP | IP | Topology | Can build a hierarchical and scalable network. | Cannot build a hierarchical network with this protocol. | The Enhanced Interior Gateway Routing Protocol (EIGRP) is an advanced distance – vector routing protocol that is used on a computer network to help automate routing decisions and configuration. The protocol was designed by Cisco systems as a proprietary protocol, available only on Cisco routers, but Cisco converted it to an open standard in 2013. EIGRP allows a router to share information it knows about the network with neighboring routers within the same logical area known as an autonomous system. Contrary to other well known routing protocols such as routing information protocol, EIGRP only shares information that a neighboring router would not have, rather than sending all of its information. EIGRP is optimized to help reduce the workload of the router and the amount data that needs to be transmitted between routers. The features that support EIGRP are the following; support for Classless Inter-Domain Routing (CIDR) and variable length subnet masking...

...Unit 1 Summary: Chapters 1,2,3,4 Chapter 1 – The TCP/IP and OSI Networking Models: * A network model sometimes also called either a networking architecture or networking blueprint refers to a comprehensive set of documents used to describe the functions of a network as a whole * The international organization for standardization (ISO) took on the task to create such a model, starting as early as the late 1970’s beginning work on what would become known as the open systems interconnection (OSI) networking model. * IP defines addresses for several important reasons. First each device that uses TCP/IP needs a unique address so that it can be identified on the network and IP also figures out how to group addresses together. * The term IP host refers to any device, regardless of size or power that has an IP address and connects to any TCP/IP network * The Current OSI Model: 1. Application 2. Presentation 3. Session 4. Transport 5. Network 6. Data Link 7. Physical Chapter 2 – LAN Fundamentals: * File Sharing: Each computer can be configured to share all or parts of its file system so that the other computers can read, or possibly read and write, the files on another computer. * File Transfers: A computer could install a file transfer server, thereby allowing other computers to send and receive files to and from that computer. * The term collision domain defines the set of devices whose frames could collide * Broadcast...

...Scenario 1: End user complains of lack of connectivity to any resource not on the directly connected network. The host cannot ping its default gateway. The output of the “ipconfig /all” command is below. Also the IP address assigned to the router for that segment is also displayed below. What do you think the problem is with the configuration of this host? PC “ipconfig /all” output (summarized) Ethernet adapter Local Area Connection: Physical Address. . . . . . . . . : 00-AB-C5-00-00-00 DHCP Enabled. . . . . . . . . . . : No IPv4 Address. . . . . . . . . . . : 192.168.40.9 Subnet Mask . . . . . . . . . . . : 255.255.255.128 Default Gateway . . . . . . . . . : 192.168.40.254 DNS Servers . . . . . . . . . . . : 8.8.8.8 Router “show ip interface brief” Router# show ip interface brief Interface IP-Address OK? Method Status Protocol GigabitEthernet0/0 192.168.40.254 YES NVRAM up up Answer: The problem is that either the IP address is wrong or the subnet mask is wrong. That is because the 192.168.40.9 IP address is not in the same subnet as the default gateway IP address (192.168.40.254). Changing the subnet mask to 255.255.255.0 or changing the IP address to 192.168.40.129 – 192.168.40.253 would resolve the problem. The ping command can be used to check for connectivity, and it was. The tracert command could have been used to see where the ping failed. Scenario 2: One user complains of lack of connectivity...

...It is learnt that the management is in the process of finalizing the VISION of PSPCL and one of the mission identified is to "attain 10,000 MW Power Generation in the state by 2020". Presently, the total installed capacity of share is 4878 MW and PS has signed PPAs with private companies setting up plants at Goindwal Sahib (540MW), Talwandi Sabo(1980 MW), Rajpura (1400 MW)and with NTPC (2640 MW with PSPCL share of 1320 MW). So the total installed capacity in the state by the end of 2014-15 is expected to be 9118 MW. In addition, has signed MOUs with private companies for setting up thermal plants in the state of more than 5000 MW capacity. In addition, presently P has allocation of 1840 MW from central sector plants which is expected to cross 470 MW in the next 5 years. As there is no difference between the powers contracted on long term basis with plants set up outside the state either by central sector or private sector companies and the PPAs signed for procurement of power with private companies setting up plants in the state so mission appears to have been secured well before 2015 without investing even a penny in any project. The question is what will be doing in the next 5 years whereas generation is concerned? In the past, the management of repeatedly argued in favour of setting up plants under state sector and has mentioned it many a times that "setting up of thermal plants in the state sector is in the interest of the state" but surprisingly this commitment...

...Gevork Darakhchyan NT 2640 Unit 10 assignment1 Frame relay migration to MPLS Frame relay | MPLS | Frame Relay is based on the PVC or Permanent Virtual Circuit. You access the network using a specialized piece of customer premises equipment called a FRAD or Frame Relay Access Device. Within the network frame routers are configured by the network operator to create your PVCs from a list of sources and destinations and your desired bandwidth or Committed Information Rate (CIR). | MPLS or Multi Protocol Label Switching is also a private network arrangement. It's designed to run on the newer IP based networks that are replacing traditional circuit switched or TDM (Time Division Multiplexing) networks. The multi-protocol aspect allows all sorts of traffic to be carried on the network simultaneously. What MPLS layers over the core IP network is a specialized label system. Each label specifies source and destination and quality of service. The labels work something like the virtual circuits of Frame Relay in that they identify where packets are coming from and where they are intended to go. | Benefits * Keeping cost of ownership and technology complexity low at point-of-sale and branch endpoints, ensuring fast service activation. * Deploy products to enable simultaneous delivery of private line, Frame Relay, and MPLS services during the transition phase to avoid service interruption. * Build MPLS-compatible traffic quality classification, performance, and quality...

...Daniel Wang NT 2640 IP Address Class Historical Significance of the address classes: Class A: the first of the address classes, which is responsible for the value ranges of IP from 0-126 and also has 16,177,214 hosts. It also has 256 networks and the most significant bits are 0000. Class B: The second of the address classes, which is responsible for the value ranges of IP from 128-191. It also has 65,534 hosts and 65,536 networks. The most significant bits are 1000 and it is also a common class among most IP addresses. Class C: the third of the address classes, which is responsible for the value ranges of IP from 192-223 the most significant bits are 1100. It only has 254 hosts but it also has 16,177,216 networks since a lot of people have their IP addresses starting with 192.xxx.xxx.xx. Class D: the fourth of the address classes, which is responsible for the value ranges of IP from 224-239. Its most significant bits are 1110, and it does not have any networks or hosts because this class is rarely considered since the start of IP addresses don’t often start with 224 and above. Class E: the fifth of the address classes, which is responsible for the value ranges of IP from 240 and above. The significant bits of this class are 1111 and just as Class D does not have any hosts or networks, the same is with this class since IP addresses do not go above 192 usually. http://www.inetdaemon.com/tutorials/internet/ip/addresses/classful.shtml Address space A: the value range is...
