A method and apparatus for registering auto-configured network addresses
includes receiving first data at a networking device connected to a host
at a physical connection. The first data is received from a first server
and indicates authentication information associated with the host. A
first message is received at the networking device from the host. The
first message requests configuration information and includes a logical
network address for the host determined at least in part by the host. A
second message is generated based on the first message and the first
data. The second message is sent to a second server that registers the
host by associating the logical network address with the first data.
