And RFC 1918 section 5 para 7:

   If two (or more) organizations follow the address allocation
   specified in this document and then later wish to establish IP
   connectivity with each other, then there is a risk that address
   uniqueness would be violated.  To minimize the risk it is strongly
   recommended that an organization using private IP addresses choose
   randomly from the reserved pool of private addresses, when allocating
   sub-blocks for its internal allocation.
