  1. 1. 2nd Irish IPv6 Summit: Dublin Castle 19th May 2010
  2. 2. History  of  Event • 1st  Irish  IPv6  Summit  (Jan  2009) – h=p:// • Organised  by  Irish  IPv6  Task  Force – h=p:// • Supported  by: – TSSG,  HEAnet,  DCENR,  other  members  of  the  Task  Force • Sponsored  by: – Science  FoundaRon  Ireland  (SFI)
  3. 3. Context:  Internet  Governance  Ecosystem • ICANN  -­‐  in  charge  of  names  and  numbers,  sets  policy • IANA  -­‐  operated  by  ICANN,  follows  policy • RIRs  -­‐  regional  number  allocaRon – AfriNIC,  APNIC,  ARIN,  LACNIC,  and  RIPE  NCC • Internet  Society  (ISOC)  -­‐  supports  the  ecosystem • Internet  Engineering  Task  Force  (IETF)  -­‐  defines  the standards  (e.g.  IPv4  and  IPv6) – Internet  Engineering  Steering  Group  (IESG) – Internet  Architecture  Board  (IAB)
  4. 4. Context:  IPv4  Address  Shortage • IPv4  has  over  4  billion  addresses • But  that  simply  is  not  enough – Fewer  that  one  for  everyone  on  the  planet – But  we  all  use  mulRple  devices – And  we’re  creaRng  new  devices  that  talk  to  each other  rather  than  being  used  directly  by  a  humans – We’ve  already  used  them  all  up,  almost
  5. 5. Context:  IPv4  Address  Shortage • We’ve  put  of  the  day  as  long  as  could – CIDR  (sub  divide  address  space  more  aggressively) – NAT  (allow  non-­‐server  devices  to  share  public  addresses) • But  now  the  Rme  is  running  out • IANA  /8  blocks  are  the  basic  unit  of  allocaRon  to Regional  Internet  Registries • PredicRons  now  indicate  the  last  of  these  blocks  will be  allocated  in  September  2011
  6. 6. Context:  IPv6 • So  there  is  no  Rme  for  a  long  debate  on  the alternaRves • The  Internet  community  has  already  agreed  on  IPv6 as  the  soluRon  to  IPv4  address  shortage  as  a problem • IPv6  has  about  340  trillion,  trillion,  trillion  addresses • In  actual  use,  addresses  are  structured  for  rouRng and  as  a  result  the  number  of  addresses  available  is effecRvely  less
  7. 7. Talks  Today  Address • End  User – Home  user  must  wait  for  ISP  to  provide  IPv6,  or  run  a tunnel  over  IPv4 • Enterprise  Networks  (private  and  public  sector) – Can  make  decision  now  to  migrate  to  IPv6 – Will  have  to  deal  with  IPv6  in  very  near  future  anyway • TelecommunicaRons  operators  and  ISPs – Offer  Internet  connecRvity – Should  be  planning  to  migrate  to  IPv6  asap
  8. 8. What  is  the  Internet? • Explosive  growth – The  defining  characterisRc  of  the  Internet  is  its  growth – This  will  stop,  unless  we  migrate  to  IPv6 – Arguably  it  has  been  one  of  the  main  drivers  of  the  whole economy,  revoluRonising  many  business  sectors • Lowest  barriers  to  service  creaRon – The  end-­‐to-­‐end  architecture  has  allowed  anyone  on  the Internet  to  offer  a  service  to  anyone  else  on  the  Internet – NAT  has  broken  this,    IPv6  can  help  reintroduce  it
