The 4 types of IP addresses.

A

Private, Loopback, Automatic Private, and Public

88
Q

These IP addresses are select ranges reserved for internal network usage and cannot be used on the public Internet.

A

Private

89
Q

These IP addresses are assigned to a device’s NIC and used to verify that the IP function is operating correctly on the device.

A

Loopback

90
Q

These IP addresses are used for hosts or computers that have requested an IP address but have not been assigned one after a certain amount of time.

A

Automatic Private

91
Q

A missing IPv4 address will generate this address, and if present, it indicates a problem.
