Link-local addresses may be assigned manually by an administrator or by automatic operating system procedures. In Internet Protocol (IP) networks, they are assigned most often using stateless address autoconfiguration, a process that often uses a stochastic process to select the value of link-local addresses, assigning a pseudo-random address that is different for each session.
The myIpAddress function has often been reported to give incorrect or unusable results, e.g. 127.0.0.1, the IP address of the localhost. [5] It may help to remove on the system's host file (e.g. /etc/hosts on Linux) any lines referring to the machine host-name, while the line 127.0.0.1 localhost can, and should, stay.

In IPv4, the method is called link-local address autoconfiguration. [1] However, Microsoft refers to this as Automatic Private IP Addressing (APIPA) [3] or Internet Protocol Automatic Configuration (IPAC). The feature is supported in Windows since at least Windows 98. [4]
Auto-configuration is the automatic configuration of devices without manual intervention, without any need for software configuration programs or jumpers.Ideally, auto-configuring devices should just "plug and play".
This message may contain the client's Client ID (Option 61, containing a unique value, traditionally a MAC address), the IP address that the server is offering, the subnet mask, the lease duration, and the IP address of the DHCP server making the offer. The DHCP server may also take notice of the hardware-level MAC address (as specified in the ...
DHCPv6 can provide this information whether it is being used to assign IP addresses or not. DHCPv6 can provide host with the addresses of Domain Name System (DNS) servers, but they can also be provided through Neighbor Discovery Protocol, which is the mechanism for stateless autoconfiguration. [1]
Wireless Zero Configuration (WZC), also known as Wireless Auto Configuration, or WLAN AutoConfig, is a wireless connection management utility included with Microsoft Windows XP and later operating systems as a service that dynamically selects a wireless network to connect to based on a user's preferences and various default settings.
Internet Protocol version 4 (IPv4) was the first standalone specification for the IP address, and has been in use since 1983. [2] IPv4 addresses are defined as a 32-bit number, which became too small to provide enough addresses as the internet grew, leading to IPv4 address exhaustion over the 2010s.
