Protocol
The two versions of IP Address.
IPv4 and IPv6
The 4 types of IP addresses.
Private, Loopback, Automatic Private, and Public
These IP addresses are select ranges reserved for internal network usage and cannot be used on the public Internet.
Private
These IP addresses are assigned to a device’s NIC and used to verify that the IP function is operating correctly on the device.
Loopback
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.
Automatic Private
A missing IPv4 address will generate this address, and if present, it indicates a problem.
APIPA
These IP addresses are used across the public Internet and are visible to other networks and devices.
Public
IP addresses can be assigned in these three ways.
Dynamic, Static, and Reserved
This type of assignment of IP address is done through the DHCP server, which assigns an IP address when a device requests one.
Dynamic
A protocol for assigning dynamic IP addresses to devices on a network.
DHCP
DHCP
Dynamic Host Configuration Protocol
These IP addresses are manually entered by an administrator or user and does not use the DHCP server.
Static
This can be done for an IP address by the DHCP server for particular devices.
Reserved
These identify computers and devices on a network without needing to remember an IP address.
