    Nothing in your arp list appears to indicate that you had involvement from
    any device other than the two you own. Of course and arp list is far from a
    complete record of activity. = uPnP (disable on router if not needed)
    224.0.0.x = Multicast IP addresses (router autodiscovery, etc)
    1:0:5e:x:x:x = Multicast MAC addresses (separate from hardware MAC
    169.254.x.x = Automatic private addressing (no DHCP server available for
    devices configured as DHCP clients) = Broadcast address for automatic private addressing space

    Airport Express Firmware 6.1 automatically checks for other WDS nodes - new
    autodiscovery feature, introduced 2004-11-15 per Apple's site. This sounds
    relevant to your issues. Did they occur after a firmware update?
