Transcript

  • 1. IPv6 http://ben.woodruff.ws/ Sunday, December 26, 2010
  • 2. Why • IPv4 limited address space • Get rid of NAT • More efficient routing Sunday, December 26, 2010
  • 3. Why not now? • Local ISPs don’t support it • Tunnel brokers (6to4) not production quality • Cost-benefit is low for most Sunday, December 26, 2010
  • 4. When? • As of November, only 3% of the IPv4 space was unallocated • Best guess I’ve heard is March 2011 for exhaustion of unallocated space Sunday, December 26, 2010
  • 5. So really, when? • Who knows? • Rough guess is 8mo after exhaustion Sunday, December 26, 2010
  • 6. Last legs for IPv4 • NAT at the ISP level • Name based virtual hosting of websites (doesn’t work with SSL) • Tighter control of allocations Sunday, December 26, 2010
  • 7. Where are the holes? • Networks NOT IPv6 enabled but with v6 compatible hosts Sunday, December 26, 2010
  • 8. Where are the holes? • No longer able to scan for hosts • But what about DNS? Sunday, December 26, 2010
  • 9. Where are the holes? • v6 is “new” • Many firewall rules weren’t written with it in mind Sunday, December 26, 2010
  • 10. Where are the holes? • The usual suspects have updated to include IPv6 support Sunday, December 26, 2010
  • 11. Where are the holes? • Try simply accessing web servers using http://their-ipv6-address/ • Likely that they don’t have a vHOST for it, so the default will be shown Sunday, December 26, 2010
  • 12. Sources • Why you want IPv6: http://en.linuxreviews.org/Why_you_want_IPv6 • Uninformed Vol 10 Article 3: http://uninformed.org/?v=10&a=3 • IPv4 Address Exhaustion: http://en.wikipedia.org/wiki/IPv4_address_exhaustion Sunday, December 26, 2010
