By default, when configuring an IPv6 address, Windows 10 generates a random number to fill out the bits needed for the NIC portion of the IPv6 address. This security measure helps conceal your device’s MAC address, and further protects your privacy by generating a new number every so often. There may be times, however, when you need your system to maintain a static IPv6 address. To do this, you can disable IPv6 autoconfiguration using the netsh utility in an elevated Command Prompt window. Do the following: 1. Open an elevated Command Prompt window. 2. Enter ipconfig/all. What is your computer’s current IPv6 address and MAC address? Carefully compare the two addresses. Are they in any way numerically related? 3. To disable the random IP address generation feature, enter the command: netsh interface ipv6 set global randomizeidentifiers5disabled 4. To instruct Windows to use the EUI-64 standard instead of the default settings, use this command: netsh interface ipv6 set privacy…
Exactly how can you tell whether every gadget on your network has a one-of-a-kind MAC address? Do you agree or disagree with this assessment? So what if I need to use the same IP address on many network connections? Is that true or false?
There is a chance that MAC addresses will be used by more than one network
interface. Why are you making the decision not to do it? Does utilizing several
network interfaces make it more likely that IP address disputes may occur? Is this
action justified in some way?

- In network security, it is important to understand port scanning. Hackers use tools to scan a network and determine if there are open ports and if they contain some sort of vulnerability. To scan ports, you first have to find active hosts on a network. Once you find active hosts and discover a list of IP addresses for those hosts, a port scan can be performed to gather information about open ports and analyze services running on those ports. A port scan is the process of sending packets to an active host's ports and learning details that can help you gain access to that host or to discover open vulnerabilities on your network. Some common ports are: Port 20 - File Transfer Protocol or FTPPort 22 - Secure Shell protocol or SSHPort 23 - Telnet protocol for unencrypted transferPort 80 - HyperText Transfer Protocol or HTTPPort 443 - HyperText Transfer Protocol Secure or HTTPS The Well Known Ports are those from 0 through 1023 We are going to simulate a port scan by filling a list with 100…arrow_forwardFor some good reasons, a network administrator has created the following configuration to the gateway router: ipv6 route ::/0 serial 0/1/0 ipv6 route ::/0 serial 0/0/0 7 Explain the main purpose of the above two configuration statements.
