Question Completion Status: QUESTION 6 The IPv6 has O options O header checksum O fragmentation anycast address feature, which is not in IPv4.
Internet protocol version 4 ( IPV4 ) Represents each IP address as a 32-bit binary number. Internet protocol version 6 ( IPV6 ) represents each IP adress as a 128-bit binary number. WHich of the following best describes the result of using 128-bit addresses instead of 32-bit adresses- 4 times as many address are available- 96 times as many addresses are available - 2^4 times as many adresses are avialabe- 2^96 times as many adresses are available

Server reply (UDP). How does the networked application running on a server know the client IP address and the port number to reply to in response to a received datagram? As the result of performing the accept () statement, the server has created a new socket that is bound to that specific client, and so sending into this new socket (without explicitly specifying the client IP address and port number) is sufficient to ensure that the sent data will be addressed to the correct client. The server will know the port number being used by the client since all services have a well-known port number. The application code at the server determines client IP address and port # from the initial segment sent by client, and must explicitly specify these values when sending into a socket back to that client. The server will query the DNS to learn the IP address of the client. Not quite. Your answer isn't correct.
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…

Using the Nmap tool complete the following tasks and store the outcome into a text file: Scan the open ports of an IP in your network domain (for 192.168.1.102) Scan all the machines in your network and list the available open ports. Create a list of target IP and scan these IP address for open ports and Operating System (OS) details.
Shell Script # 5 - NetworkTest.sh Create a fifth script called (NetworkTest.sh). This script will have one subroutine. 1. The subroutine will check if the system is online (Connected to the internet). If the system is connected to the internet, then perform the following: Ping the loopback IP address. Ping the gateway with 8 packets each packet is 1KB. Query the Domain Name System to qu.edu.qa. Save the results in a file called /tmp/PINGRESULTS.TXT. ● ● Otherwise, perform the following: • Ping your local machine. ● Display IP configuration and Routing Table of your Machine. Store results in a file called /tmp/NETINFO.TXT Finally reboot the system automatically after 20 seconds.
Task 2: Access Control Lists You will need to work out which interface on which router this needs to be applied to. Each ACL must work and be seen to work. Stop any IP address from 10.0.0.128 to 10.0.0.191 from pinging 123.123.123.123 - yet allow all other addresses Creating an ACL that meets the above 'selected' criteria Proving that a change of IP address, other than those allocated to the PC's also demonstrates the operation of the ACL. Also prove that you are still able to ping to 99.0.0.2 irrespective of device IP address
