DHCP has the advantage of allowing arbitrary configuration information to be passed, and already having a defined format for the delivery of most if not all standard IP configuration information. On the other hand, arp is light-weight. :) I prefer to not have the machine sniff the network to find config information -- might get confused if there are multiple routers on the network already (and hence multiple gateways), or multiple IP ranges on the network. This way the configuration server gets to specify what IP it comes up on, preventing conflicts and allowing you to find your new machine once it comes up :). You also know that it has come up as DHCP involves a 2-phase process with acknowledgement -- if you don't get DHCPREQUEST then it didn't like your DHCPOFFER, etc. To prevent the host from accepting normal DHCPOFFERs from its DHCPDISCOVER, we require that the DHCP server provide a vendor tag indicating it is the/a configuration server. ISC has a formidible-looking DHCP server these days.
