    What do you mean when your computers are off?  I assume X.X.55.121 is one
    of yours?  That machines that belongs to that IP address is off when this
    traffic is being logged?

    Those first two (all I checked) are root DNS servers.  This makes it look
    exactly like you've got a copy of bind running on X.X.55.121, and it's
    just trying to resolve names.  However, if that machine is supposed to be
    off...
