Description
Auto-IP describes a method by which a host may automatically configure an interface with an IPv4 address in the 169.254/16 prefix that is valid for Link-Local communication on that interface. This is especially valuable in environments where no other configuration mechanism is available. Refer to the following RFCs for complete details:
- RFC 3927: Dynamic Configuration of IPv4 Link-Local Addresses
- RFC 5227: IPv4 Address Conflict Detection
- Version:
- 1.7.6
