The GOLDEN RULES for
allocating IP numbers


  1. All hosts on the same physical network must use the same unique prefix (network number)
    10101001 11011110 00010000 0xxxxxxx
    

  2. The remaining part (host number) must be different for each host
    10101001 11011110 00010001 0xxxxxxx
    

  3. Host numbers of all zeros and all ones are reserved
