Well, udhcpd assumes this approach, which seems to be a consolidation of given responses. Whereas dhclient will give 6 or 7 different responses, udhcpd only returns (dhclient equivilents in parenthesis) deconfig (PREINIT), bound (BOUND), and renew (RENEW). (RELEASE) is given through a SIGUSR2 signal from a kill command and (TIMEOUT) simply exits the program (I think). What this amounts too is that the only responses assumed to be returned from ISP are these three regardless of server platform. The only reason given in the documentation for even calling a "renew" script is the fact that udhcp assumes that "renew" does _not_ change the ip address, only the gateway, wins, or dns server(s) information. To be on the safe side, I went ahead and scripted a possible addy change, but the docs indicate that this was un-needed even though the gateway and route would possibly change. Now whether this means a hill of beans to dhclient is another story altogether, but on a renew signal the route dependent applications should be reloaded on the by chance that this _might_ happen. It is not likely to happen within the US IMHO, but many non-US ISP's (especially with PPP) are well known to change ip addresses within a couple of hours which the DHCP clients must be able to handle. I think it is normal behavior for the client programs, though the reasoning most likely will never affect you personally.
