Macos – Self-assigned IP address

dhcpmacbookmacos

I sometimes have problems dropping IP addresses after changing networks and get stuck with a self-assigned IP that I cannot drop by hitting the renew "DHCP Lease" button on my Mac OS X.5 Leopard. The only work around is to manually give myself a "good" IP, shut down my computer, then boot up and switch back to regular DHCP. Any ideas?

  • Somtimes issues like these can arise from malformed network preferences. Try deleting (or just moving/renaming) these files:

    /Library/Preferences/SystemConfiguration/preferences.plist
