Are you sure that there isn't another dhcp server running on the network? Have you checked in /var/log/messages for dhcp logs from the time the ip was assigned to your laptop? > I should say that WiFi works perfectly well with this wrong address. > But it has made me realize that I am very hazy about how dhcp works, > and how exactly dhcpd determines the addresses it will give out.

Maybe the DHCP FAQ will be useful? http://www.dhcp-handbook.com/dhcp_faq.html I have my dhcp server give out specific addresses to some systems based on the mac address and that's worked well for me. So I know the software isn't universally broken. The trick is in finding out why it's not working on your system. Hopefully your logs will provide some clues to you. If not, perhaps post your dhcpd.conf. > I saw incidentally that something or someone (I assume a yum update) > had moved /etc/dhclient.conf to dhclient.conf.bak I have no dhclient.conf (or .bak) on my system.

If you're sure of that, please find out what overwrote the file and file a bug report. Just taking stabs in the dark and saying someone else is lacking in common sense doesn't do anything to get real problems fixed. :-) -- Todd OpenPGP -> KeyID: 0xBEAF0CE3 | URL: www.pobox.com/~tmz/pgp ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Honesty is the best policy, but insanity is a better defense.
