5. Why IPv6?

24. The Problem? SIP NAT

25. Oh, and by the way... (sorry... we still have NAT-like networks with IPv6...)

26. And then there is...

27. Challenge #1 For VoIP and UC Apps: How Many Digits Is That?

28. See the problem?

29. See the problem?

30. IPv4 192.168.20.12

31. IPv6 2001:db8:34a5:23:aa1f:12f4:9009:1234

32. IPv6 Address Compression 2001:db8:34a5:0:0:0:0:1 2001:db8:34a5::1(oh, and they aren’t case-sensitive)

33. IPv6 Address Compression 127.0.0.1 ::1 0.0.0.0 ::

34. DNS is your friend!

35. Challenge #2 For VoIP and UC Apps: Where’s The Nearest Port?

36. IPv4 Port Numbers 192.168.20.12:5060

37. IPv4 Port Numbers in IPv6? 192.168.20.12:5060 2001:db8:34a5::1234:5060

38. IPv6 Port Numbers [2001:db8:34a5::1234]:5060

39. IPv6 addressing http://[2001:db8:34a5::1234]/index.html http://[2001:db8:34a5::1234]:8080 sip:dan@[2001:db8:34a5::1234] sip:dan@[2001:db8:34a5::1234]:5060

40. DNS is your friend!

41. Challenge #3 For VoIP and UC Apps: What’s the Address?

42. IPv6 – Multiple Addresses / Interface 192.168.20.12 2001:db8:34a5:92:21c:a5ff:fe12:3a80(global) fe80::21c:a5ff:fe12:3a80(link-local)

43. IPv6 – Neighbor Discovery No More DHCP For Address Assignment(well, unless you want it) Router Advertisements Also Replaces ARP

44. IPv6 – Address Creation 2001:db8:34a5:92:21c:a5ff:fe12:3a80 Router Advertisement Autoconfiguration fromEthernet Address

45. DNS is your friend!

46. Challenge #4 For VoIP and UC Apps: How Many A’s Do You Want With That?

47. IPv4 and DNS example.com 3600 IN A 192.168.20.12

48. IPv6 and DNS example.com 3600 IN A 192.168.20.12 example.com 3600 IN AAAA 2001:db8:34a5::1234

49. IPv6 DNS Fun What if DNS gives a AAAA.... but your system doesn’t have “real” IPv6 connectivity? (You can retrieve AAAA records over IPv4!)

50. UNhappy Eyeballs DNSSvr example.com A 192.168.20.12 example.com AAAA 2001:db8:34a5::1234 AAAA ? You (a long time later...) A ?

51. Happy Eyeballs DNSSvr example.com A 192.168.20.12 example.com AAAA 2001:db8:34a5::1234 AAAA ? You A ? (sent at same time; whichever replies first wins)

53. Challenge #5 For VoIP and UC Apps: What Lies Buried Within?

54. How Do You Store IP Addresses? Memory? Databases? Config Files? Room for two? (or more?)

55. Config Files <category name="SIP"> <item name="Server1">127.0.0.1:5060 </item> </category>

59. RFC 6157 RFC 6157 “IPv6 Transition in the Session Initiation Protocol (SIP)” tools.ietf.org/html/rfc6157

60. SIP Architecture SIP Proxy A SIP Proxy B SIP SIP SIP Alice Bob Media (RTP, MSRP, etc.)

61. SIP Reality Internet (or WAN) SIP Proxy A SIP Proxy B SIP Proxy N SIP Proxy D SIP Proxy C SIP SIP SIP SIP SIP SIP Media Proxy A Media Proxy B Alice Bob Media Media Media

62. “SIP” = Multiple Protocols SIP SDP RTP

63. IPv4/IPv6 Fun Communicating between IPv4 client and IPv6 client through a proxy Record-Route: <sip:2001:db8::1;lr> Record-Route: <sip:192.0.2.1;lr> Mixed communication across a path of proxies Mixed communication: IPv6 for SIP, IPv4 for media

64. IPv6 and SDP Only allows a single IP address per media stream (“c=“ parameter) c=IN IP4 192.168.20.12 c=IN IP6 2001:db8:34a5::1234 Multiple proposals for additional SDP parameters ex. ANAT - RFC 4091 & 4092 – now deprecated by ICE The IETF way forward is ICE – RFC 5245

65. NAT, NAT, NAT... STUN, TURN, ICE (RFC 5245)

66. Discovery of SIP Servers User agents need to find SIP servers/proxies DHCPv6 SIP Options in RFC 3319 DNS SRV, NAPTR and AAAA Records (RFC 3263)

67. Other IPv6 Considerations Other interfaces Web and management systems Logging APIs Custom SIP headers Multi-vendor interoperability SBC and firewall support for SIP over IPv6

70. SIPit Test Events sipit.net SIPit 28: “68% of the implementations present supported IPv6.”
