This range of 31 contiguous /24 networks can be covered by the
following specifications:

  161.241.51/24;
  161.241.52/22;    # covers 52-55 (3rd octet divisible by 4)
  161.241.56/21;    # covers 56-63 (3rd octet divisible by 8)
  161.241.64/20;    # covers 64-80 (3rd octet divisible by 16)
  161.241.81/24;
