Answer 1

Valid IP multicast addresses from the given options are 225.1.2.3 and 239.255.0.1. The other addresses listed are private IP addresses or invalid IP address formats.

Step-by-step explanation:

The IP multicast addresses are a range of IP addresses used for multicast traffic and are defined by the Internet Assigned Numbers Authority (IANA) as the range from 224.0.0.0 to 239.255.255.255. For the options provided, the valid IP multicast addresses would be:

• 225.1.2.3
• 239.255.0.1

The other addresses provided are not valid IP multicast addresses:

• 192.168.1.1 is a private IP address commonly used for local networks.
• 172.16.0.1 is also a private IP address used within private networks.
• 300.0.0.1 is not a valid IP address format because the first octet must be between 0 and 255.
