2nd Irish IPv6 Summit: Dublin Castle19th May 2010

History  of  Event

• 1st  Irish  IPv6  Summit  (Jan  2009)– h=p://www.ipv6.ie/summit2009

• Organised  by  Irish  IPv6  Task  Force– h=p://www.ipv6.ie/

• Supported  by:– TSSG,  HEAnet,  DCENR,  other  members  of  the  Task  Force

• Sponsored  by:– Science  FoundaRon  Ireland  (SFI)

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  thestandards  (e.g.  IPv4  and  IPv6)– Internet  Engineering  Steering  Group  (IESG)– Internet  Architecture  Board  (IAB)

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  eachother  rather  than  being  used  directly  by  a  humans

– We’ve  already  used  them  all  up,  almost

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  toRegional  Internet  Registries

• PredicRons  now  indicate  the  last  of  these  blocks  willbe  allocated  in  September  2011

Context:  IPv6

• So  there  is  no  Rme  for  a  long  debate  on  thealternaRves

• The  Internet  community  has  already  agreed  on  IPv6as  the  soluRon  to  IPv4  address  shortage  as  aproblem

• IPv6  has  about  340  trillion,  trillion,  trillion  addresses• In  actual  use,  addresses  are  structured  for  rouRngand  as  a  result  the  number  of  addresses  available  iseffecRvely  less

Talks  Today  Address

• End  User– Home  user  must  wait  for  ISP  to  provide  IPv6,  or  run  atunnel  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

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  wholeeconomy,  revoluRonising  many  business  sectors

• Lowest  barriers  to  service  creaRon– The  end-­‐to-­‐end  architecture  has  allowed  anyone  on  theInternet  to  offer  a  service  to  anyone  else  on  the  Internet

– NAT  has  broken  this,    IPv6  can  help  reintroduce  it
