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
In classful addressing, the IP address space is divided into 5 classes. Indicate the classes of each of the following addresses expressed in binary. Indicate how the class was identified. 3.1.1 00000001 00001011 00001011 11101111 3.1.2 11000001 10000011 00011011 11111111 3.1.3 10100111 11011011 10001011 01101111 3.1.4 11110011 10011011 11111011 00001111
Find the class of the following two IP addresses (both are classful addresses),as well as their netid and hostid: a. 104.37.3.6 b. 208.34.54.12
IP Address Discovery Step 1: Develop a list of five websites (you may not use Google.com in your list). Step 2: Using DNS (a program called nslookup or dig), look up the IP addresses of each of the websites. Example Use nslookup to find the IP addresses of Google: Tracys-MBP-3:~ tlavans nslookup www.google.com 192.168.1.1 Server: Address: 192.168.1.1#53 Non-authoritative answer: Name: www.google.com Address: 172.217.6.4| Step 3: Using the same program, look up the names of the machines with an IP address close to the IP addresses of the websites you listed in Question 3 (use the same first three octets of the IP address and very the last octet). You may need to try quite a few to find one that works. List your findings for at least three of the five websites you listed. Original Website IP address Discovered IP address Machine Name of Discovered IP Original Website URL 1. 2. 3. 4. 5. 1 Add a table like the example shown to record your results. 2 How might an attacker use this same…

An ISP is granted a block of addresses starting with 130.100.0.0/16. The ISP needs to distribute these addresses to 4 large companies. Each company requires 1024 IP addresses. Write the address ranges for these companies into the following table with /n notation. Company First address Last address 1 2 3 4
Addresses starting with fe80 are called link-local IPv6 addresses. True or false
In terms of sockets: A desktop computer with the IP address 192.168.0.5 is running multiple applicationsWhat are the steps involved when the user opens their browser and visits the website discord.com, make sure to take account of the protocols involved in each step.
Internet protocol version 6 (IPV6) has been introduced to replace the previous version (IPV4), Which of the following best describes a benefit of IPV6 over IPV4? A IPV6 addresses are shorter than IPV4 addresses, which allows for faster routing of packets. B IPV6 allows for a greater number of addresses than IPV4, which allows more devices to be connected to the Internet. IPV6 eliminates the use of hierarchy in addressing, making addresses easier to use. D IPV6 allows users to bypass older security protocols so that data can be sent peer-to-peer without the use of routers.
