Is it still enough?

• Assume...:

  • RIRs request new block every 18 month

• Then...

  • The block currently assigned by IETF (1/8TH IPv6 space) is about to run out by 2158
  • More than 5/8TH IPv6 address space will be still available
  • (NB: 000/3 and 111/3 prefixes are reserved for special use)
