   And may never happen. But a shortage on IPv6 prefixes can happen IMHO, if /48s   
   are given away easily. There is only 35 million million (35 trillion) /48   
   blocks in the current global 2000::/3 pool. A trillion is not that much, I   
   think a trillion bacteria live on 1 human person.   
      
   Do you know if the 2000::/3 global pool can be extended if necessary?   
      
   OTOH, we don't need an IPv6 *prefix* per each bacteria, one IPv6 *address* per   
   bacteria is sufficient, so a /64 for each human being is more than enough.
