You don't need bitwise operators to get bitwise operations, though.  What's
wrong, in your case, with having them as functions?

  netmask = math.or(netmask, 0x000000FF)

doesn't seem any worse to me than

  netmask = netmask | 0x000000FF


  flag = math.set(flag, 10)

is actually clearer, in my opinion, than

  flag = flag | (1<<10)
