Question 2Which of the following is an example of an IPv4 address?1 point172.16.254.100-B1-D0-63-C2-2625, 443, 202001:0db8:85a3:0000:0000:8a2e:0370:7336

The example of an IPv4 address from the options given is 172.16.254.1.

Here's why:

IPv4 addresses are numerical labels assigned to each device participating in a computer network that uses the Internet Protocol for communication. These addresses are used in the lower layers of the two most common protocols (TCP/IP).

An IPv4 address consists of four numbers separated by periods. Each number can be zero to 255. For example, 1.1.1.1 or 123.123.123.123 are valid IPv4 addresses.

So, from the options given, 172.16.254.1 fits this description.

The other options are not valid IPv4 addresses. For example, 1-B1-D0-63-C2-26 appears to be a MAC address, which is a unique identifier assigned to a network interface controller. 25, 443, 202 is just a series of numbers separated by commas, not periods. And 2001:0db8:85a3:0000:0000:8a2e:0370:7336 is an IPv6 address, which is a newer version of IP address that uses a different format.
