What is IP address?Each device connected to a computer network that uses the Internet Protocol is given a unique numerical label known as an IP address. In most networks, IP addresses are assigned to devices dynamically by a DHCP (Dynamic Host Configuration Protocol) server, which assigns a unique IP address to each device on the network.If a device is unable to obtain a valid IP address from the DHCP server, it may use an APIPA address instead. APIPA addresses are reserved for use in situations where a device is unable to obtain a valid IP address from the DHCP server, and are in the range of 169.254.0.0 to 169.254.255.255. When a device uses an APIPA address, it means that it is unable to communicate with the DHCP server and may not be able to access the internet or other resources on the network.To learn more about IP address refer :
