It's the loopback network. What other server could it be?

As others pointed out, this is apparently a Linux extension to the 
loopback interface -- giving it a wider subnet mask automatically 
aliases the other addresses in the range.  But this is done in a way 
that BIND can't take advantage of through the normal socket calls.
