Packet Tracer - Configure NAT for IPv4  Objectives         Configure Dynamic NAT with PAT         Configure Static NAT Background / Scenario In this lab, you will configure a router with dynamic NAT with PAT. This will translate addresses from the three internal LANs to a single outside address. In addition, you will configure static NAT to translate an internal server address to an outside address. Instructions In this activity you will only configure router R2. Use a named ACL to permit the addresses from LAN1, LAN2, and LAN3 to be translated. Specify the LANs in this order. Use the name R2NAT. The name you use must match this name exactly. Create a NAT pool named R2POOL. The pool should use the first address from the 209.165.202.128/30 address space. The pool name you use must match this name exactly. All translated addresses must use this address as their outside address. Configure NAT with the ACL and NAT pool that you have created. Configure static NAT to map the local.pka…

Dynamic Host Configuration Protocol (DHCP): Suppose you purchase a wireless router and connect it to your cable modem. Also suppose that your ISP dynamically assigns your connected device (that is, your wireless router) one IP address. Also suppose that you have seven PCs at home that use 802.11 to wirelessly connect to your wireless router. How are IP addresses assigned to the seven PCs?

Networking: Please only answer if you are 100% sure   Given an Ethernet frame carrying an IP packet bearing a host destination address, a switch   a) sends it out all ports   b) sends it out a particular port according to the destination IP address   C) sends it out a particular port according to the destination Ethernet address   d) sends it out a subset of ports according to the IP address’s subnet

An IPV6 client dynamically (automatically) receives the IPV6 address for its default gateway: O From a Router Advertisement message or a DHCPV6 server O From a Router Advertisement message O From an IPV6 Gateway server O From a DHCPV6 server The protocol that a device will use to resolve a known domain name such as www.google.com, to an IPV4 or IPV6 address is: O DNS O FTP O SMTP O DHCP Match the IPV4 host address with the proper IPV4 network address. Note: The subnet mask of the host address also applies to the network address. 10.5.12.3 255.255.0.0 [Choose] 10.5.12.3 255.255.255.0 [Choose] 10.5.12.3 255.0.0.0 ( Choose] Which of the following operating systems support IPV6 by default? (choose all that apply) O Apple MacOS O Microsoft windows O Apple IOS O Android O Linux

IKT204-G H21, IP miscellaneous 14 Only one of the claims below is correct, the others are wrong or meaningless. Select the correct alternative. Select one alternative: If two IP datagrams containing segments to a TCP connection are received in the wrong order, the router will reorganize them so that they are forwarded in correct order. O The smallest header size of IPV4 is 20 bytes, but it may be larger. When an IP datagram is discarded in a router due to overload, then the router will send an ICMP message back to the sender, so that the IP protocol can retransmit the datagram. If the traffic load in a router is too large, then it will reduce its Receive Window, and use ICMP to warn all senders about the new and smaller Receive Window.

Static IP addresses are used when a host on your network delivers a service that requires the server to always use a certain IP address. Which IP addressing technique is the best to utilize when manually assigning an IP address? and how did this come to be the case?

Q2: True or false: In internetwork (interconnected networks) we do not need addressing at data link layer because routers can use IP addresses to route packets all the way to the end-destinations. Please explain in a very few words why this is true or false.

A default static route is similar to a default gateway on a host. The default static route specifies the exit point to use when the routing table does not contain a path for the destination network. A default static route is useful when a router has only one exit point to another router, such as when the router connects to a central router or service provider. To configure an IPV4 default static route, use the following command: Router# ip route 0.0.0.0 0.0.0.0 { exit-intf | next-hop-ip} O True O False

Part1: This question has 12 requests so I will send it in 6 parts: 1- Configure hostnames on the routers according to the Lab Topology diagram. 2- Configure IP addresses on R1 according to the Lab Topology diagram

A router receives a packet with a destination address that is not found within its routing table. The router is configured to send all such packets to a specific next hop address. What is this next hop address called? Dynamic route Discard route Final route Default route

UDP Echo ApplicationA UDP Echo program is a simple network application that demonstrates the basicprinciples of UDP communication. In this program, a server listens for incoming UDPpackets from clients, and when it receives a packet, it echoes (sends back) the samepacket to the client. The client sends a message to the server, and the server returns thesame message. It's often used for testing network connectivity and understanding thefundamentals of UDP communication.   (Answer the following question using python) Implement both the server and client components of this UDP Echo program whileadhering to the features outlined below. Please ensure that your implementation followsgood coding practices and provides clear prompts and feedback to the user, making ituser-friendly and robust. Please refer to the class example to guide your implementation. 1) UDP Echo Server Receiving and Displaying Messages: The UDP Echo server should be able toreceive messages sent by clients. For each…

Computer Science You are requesting a webpage with three images stored in three different servers. One of the images resides on the same server as the webpage. Assuming that you are using HTTP/1.1, and your web browser can open up to 3 parallel connections. Ignore transmission time, how many persistent TCP connections will you need? And how many RTTs will you need to get the entire web page displayed? Type your answer in the order of the question asked, separated by a comma, no unit of measurement should be used, no space.

A socket is one endpoint of a two-way communication link between two programs running on the network. A socket is bound to a port number so that the TCP layer can identify the application that data is destined to be sent to. An endpoint is a combination of an IP address and a port number.Discuss about the different types of socket calls using in TCP &UDP.

MC9: In wireless LAN communication, MACA is widely used. In this protocol, in order to avoid collision, a sender can send sender is granted the privilege to send a frame to the receiver only after it receives request signal to a receiver. The replied from the receiver. RTS, RTS CTS, CTS RTS, CTS CTS, RTS

FTP stands for File transfer protocol. FTP is a standard internet protocol provided by TCP/IP used for transmitting the files from one host to another. It is mainly used for transferring the web page files from their creator to the computer that acts as a server for other computers on the internet. It is also used for downloading the files to computer from other servers.   What is the difference between active and passive FTP that makes stateful packet filtering a good idea?
