  1. Adding IPv6 to the application layer APNIC 27 Manila 2009 - IPv6 in 3D Adding IPv6 to the application layer • Koichi Taniguchi • livedoor Co., Ltd. • Feb 25th, 2009

  2. Adding IPv6 to the application layer www.livedoor.com (*) 2.3 billion PV/month 23 million UU/month * autumn 2008 www.data-hotel.net LIVEDOOR/AS17707 APNIC member APNIC 27 Manila 2009 - IPv6 in 3D Background EDGE Co.Lab v6 provides IPv6 testing environment.

  3. Adding IPv6 to the application layer APNIC 27 Manila 2009 - IPv6 in 3D Problems at the beginning • A lot of problems. • What I need to do? • How can I develop web applications on IPv6? • Not found any useful tips, hints.

  4. Adding IPv6 to the application layer APNIC 27 Manila 2009 - IPv6 in 3D Research and development • I researched and developed. • Blogged it. • "8 tips how to add IPv6 to your application if you don't have enough knowledge about it" • http://tinyurl.com/IPv6-dev-ja • English version is brought to you now!

  5. Adding IPv6 to the application layer APNIC 27 Manila 2009 - IPv6 in 3D #1 You need IPv6 connectivity • Each gateways should handle IPv6. • Each OS should handle IPv6. • ... or IPv4 client -> IPv6 HTTP proxy • Some of enterprise load balancer often don’t support IPv6.

  6. Adding IPv6 to the application layer APNIC 27 Manila 2009 - IPv6 in 3D #2 SSL server ID is same as before • Using SSL • IPv4 server ID <=> IPv6 server ID(same!) • Established -> SSL server key exchange (immediately) • It doesn’t matter which version of IP you’re using.

  7. Adding IPv6 to the application layer APNIC 27 Manila 2009 - IPv6 in 3D #3 Easy Apache configuration • Apache 2.x (or later) + APR (Apache Portable Runtime) are IPv6 ready! • There are few differences.

  8. Adding IPv6 to the application layer Listen NameVirtualHost <VirtualHost> : </VirtualHost> Listen 192.0.2.36:80 NameVirtualHost 192.0.2.36:80 <VirtualHost 192.0.2.36:80> : </VirtualHost> Listen 192.0.2.36 NameVirtualHost 192.0.2.36 <VirtualHost 192.0.2.36> : </VirtualHost> APNIC 27 Manila 2009 - IPv6 in 3D #3 Easy Apache configuration • IPv4

  9. Adding IPv6 to the application layer Listen NameVirtualHost <VirtualHost> : </VirtualHost> Listen 2001:db8::dead:beef:80 NameVirtualHost 2001:db8::dead:beef:80 <VirtualHost 2001:db8::dead:beef:80> : </VirtualHost> Listen [2001:db8::dead:beef]:80 NameVirtualHost [2001:db8::dead:beef]:80 <VirtualHost [2001:db8::dead:beef]:80 > : </VirtualHost> APNIC 27 Manila 2009 - IPv6 in 3D #3 Easy Apache configuration • IPv6

  10. Adding IPv6 to the application layer Allow Deny Allow from 192.0.2.8 Deny from 192.0.2.16 Allow from 192.0.2.8/255.255.255.249 Deny from 192.0.2.16/255.255.255.249 Allow from 192.0.2.8/29 Deny from 192.0.2.16/29 Allow from 192.0.2.8/29 Deny from 192.0.2.16/29 Allow from 2001:db8::c0:ffee/10 APNIC 27 Manila 2009 - IPv6 in 3D #3 Easy Apache configuration • Exceptional case

  11. Adding IPv6 to the application layer APNIC 27 Manila 2009 - IPv6 in 3D #4 ping and traceroute aren’t able to use on IPv6 • We usually use ping and traceroute command. • Most of connecting commands are suffixed with “6”. % ping6 2001:db8:bad:face::dead % traceroute6 2001:db8:bad:face::dead C:\WINDOWS>tracert6 2001:db8:bad:face::dead

  12. Adding IPv6 to the application layer APNIC 27 Manila 2009 - IPv6 in 3D #5 Use AAAA record in DNS • We use A record. • Names won’t be resolved to IPv6 address. • Add IPv6 entries to the AAAA (quad-A) record.

  13. Adding IPv6 to the application layer APNIC 27 Manila 2009 - IPv6 in 3D #6 Which version of IP is the client using? • Dual-stack and same hostname. • Vary based on the version. • REMOTE_ADDR environment variable. • You don’t need to check the format of addresses strictly.

  14. Adding IPv6 to the application layer APNIC 27 Manila 2009 - IPv6 in 3D #6 Which version of IP is the client using? • Listening to proxied requests from reverse proxy. • Add extra header on reverse proxy with using mod_headers.

  15. Listen 80 # IP-based virtual hosting <VirtualHost [2001:db8::babe::face]:80> ServerName babeface.example.com RewriteEngine On : RequestHeader set X-IP-Version 6 </VirtualHost> <VirtualHost 192.0.2.1:80> ServerName babeface.example.com RewriteEngine On : RequestHeader set X-IP-Version 4 </VirtualHost> Listen 80 # IP-based virtual hosting <VirtualHost [2001:db8::babe::face]:80> ServerName babeface.example.com RewriteEngine On : RequestHeader set X-IP-Version 6 </VirtualHost> <VirtualHost 192.0.2.1:80> ServerName babeface.example.com RewriteEngine On : RequestHeader set X-IP-Version 4 </VirtualHost> Adding IPv6 to the application layer APNIC 27 Manila 2009 - IPv6 in 3D #6 Which version of IP is the client using?

  16. Adding IPv6 to the application layer APNIC 27 Manila 2009 - IPv6 in 3D #6 Which version of IP is the client using? • Getting IP version. • HTTP_X_IP_VERSION environment variable is 4 or 6.

  17. Adding IPv6 to the application layer APNIC 27 Manila 2009 - IPv6 in 3D #7 Expand the column length • To save remote addresses into the DB. • IPv4 • IPv6 • INET_ADDRSTRLEN (16) - 1 (nul)-> INET6_ADDRSTRLEN (46) - 1 (nul) • 15 bytes -> 45 bytes 255.255.255.255 FFFF:FFFF:FFFF:FFFF:FFFF:FFFF:255.255.255.255

  18. Adding IPv6 to the application layer APNIC 27 Manila 2009 - IPv6 in 3D #8 Check the access log parser • Many access log parsers. • Some of them are failed to parse some lines (including IPv6 address). • Check your parser.

  19. Adding IPv6 to the application layer APNIC 27 Manila 2009 - IPv6 in 3D Critical issues • Web application developers: • are poorly informed about IPv6. • have misunderstandings of IPv6. • know that IPv4 will be exhausted. • aren’t sure when it will be exhausted. • hope that some new technology will appear to avoid IPv4 exhaustion. • aren’t motivated to add IPv6. • think that IPv6 doesn’t have any advantages. • don’t think that IPv4 has some serious disadvantage.

  20. Adding IPv6 to the application layer APNIC 27 Manila 2009 - IPv6 in 3D Critical issues Imagine The all of interesting websites will be phased out in 2011.

  21. Adding IPv6 to the application layer APNIC 27 Manila 2009 - IPv6 in 3D Conclusion • Please call out and introduce the fact to some L7 developer you know. • I wish this slides will be Bible for web application developers. Bridging the layers is our task.
