Developed from the Zeroconf IETF draft, autoipd is an io-pkt* module that automatically configures the IPv4 address of your interface without the need of a server (as per DHCP) by negotiating with its peers on the network. This module can also coexist with DHCP (dhclient), allowing your interface to be assigned both a link-local IP address and a DHCP-assigned IP address at the same time.
