5. Transit
• Any decent transit provider can provide
native IPv6 connectivity these days
6. Transit
• Any decent transit provider can provide
native IPv6 connectivity these days
• If your transits don’t provide IPv6:
• get rid of them and find transits that take their job
seriously
8. Content - reasons
• Why do content providers deploy IPv6?
• Offer better service than over (slowly degrading) IPv4
• More visibility (addresses not hidden or shared)
• Logging, ACLs, traceability etc.
• GeoIP based services
• Etc.
9. Content
• The big global content providers have
shown that providing content on IPv6 can
be done safely
10. Content
• The big global content providers have
shown that providing content on IPv6 can
be done safely
• Before World IPv6 Day / Launch there were some issues
• Happy Eyeballs (RFC 6555) was unfortunately
needed, but it has helped a lot!
• A combination of better services, better software and
better testing have made IPv6 reliable
11. Content - remaining issues
• There are some remaining issues though
• Not all data centres and hosting services support IPv6
yet
• Some CDNs charge a monthly extra for IPv6
(outrageous!)
• Some content providers think there are no IPv6 eyeballs
13. Content - work to be done
• Slovenia and Czech Republic lead at the
moment
• Not much progress since World IPv6
Launch :-(
• But providing content on IPv6 is not that
hard!

15. Eyeballs - reasons for users
• This is where the IPv4 address shortage is
really going to cause pain
• Access services use the most address space
• Users behind NAT (NAT444, DS-Lite)
or only a limited number of ports (MAP)
16. Eyeballs - reasons for ISPs
• IPv4 is getting expensive
• Huge shortage on transfer market
• Investments in address-sharing solutions
• Moving traffic to IPv6 saves money on IPv4
side
• And services with large traffic amounts like YouTube and
Netflix are available over IPv6!
21. Conclusions
• IPv6 Transits are available
• IPv6 Content stable since World IPv6
Launch
• This needs to change!
• But high-traffic websites are already available over IPv6
• IPv6 Eyeballs is growing fast
• Often thanks to a few huge players deploying IPv6
22. Conclusions
• No apparent link between content and
eyeballs:
• Leaders in content are behind in eyeballs
• Leaders in eyeballs are behind in content
• Big international content providers
dominate,
so maybe this is not that important
