In the IPv4 address 93.184.216.34, which part represents the device?

93 34 184 216

Correct Answer:

Explanation:

IPv4 addresses are four numbers, called octets, separated by dots. In many networks the first three octets specify the network, and the last octet identifies the specific device on that network (when the common subnet mask 255.255.255.0 is used). So for 93.184.216.34, the network part is 93.184.216 and the device on that network is the final octet, 34. The middle octets aren’t the device; they’re part of the network address.
