5 NOW LET S GET STARTED FUNDAMENTALS OF IPV6 June 18, 2014

6 Bill Coward Principal Architect Cox Communications 25 years experience with Information, Telephony and Networking Technologies. Lead Architect responsible for technical leadership and direction of the IPv6 deployment at Cox. Member of the CEA IPV6 Transition Working Group and the DLNA IPV6 Task Force.

7 AGENDA History of TCP/IP Why IPv6 IPv6 Advantages IPv6 Anatomy IPv6 Address Types Packet Comparison IPv6 Protocols Transition Technologies Miscellaneous Whatnots

8 HISTORY OF TCP/IP In the early 1970 s Vint Cerf and Bob Kahn thru their work with DARPA conceptualized and spec d four versions of the TCP suite of protocols (RFC 675, v4 793): TCPv1, TCPv2, TCPv3 and IPv3 Hardware Interoperability TCP and IP were combined to create TCP/IPv4 Other versions TCP and IP were deprecated in TCP/IPv5 (aka Internet Stream Protocol or ST RFC 1819)

9 WHY IPV6 Devices on the Internet require a unique address. 30% of World Population 7B/2B Internet Users IPV4, 32 bits, 4.2B Unique Addresses, 1980 IPV6, 128 bits, 340 Undecillion (38 zeros, TTT) = 96 2^96 = 79TT x IPv4 addresses IPV4 is not compatible with IPV6, Really?

10 IPV6 ADVANTAGES RFC 2460 Scalability End-to-End Addressing (NO NAT) Auto-Configuration Multicast Routing Extension Support Built-in Security

11 IPV6 ANATOMY 16 bit hexadecimal characters Not case sensitive 0DB8 = 0db8 2001:0db8:85a3:0000:0000:8a2e:0370:0004 Fully Qualified IPv6 Address 2001:db8:85a3:0:0:8a2e:370:4 Leading zeros 2001:db8:85a3::8a2e:370:4 Zero Compression :: (only once) Loopback = 0:0:0:0:0:0:0:1 or ::1

12 POLL QUESTION 1 Can you find the mistake? A) 2001:0db8:85a3:0000:0000:8a2e:0370:0004 B) 2001:db8:85a3::8a2e370:4 C) 2001:0db8:85a3::8a2e:0370::0004 D) 2001:db8:85a3:0:0:8a2e:370:4 E) All entries are correct

13 IPV6 ADDRESS TYPES Unicast Global (GUA 2001::/ net prefix/int id) Unique Local (ULA FC00::/7 private ip) Link Local (LLA FE80::/10 ND,DAD,) Special Addresses (2001:bd8::/32) Multicast FF00::/8 Anycast No more Broadcast Global Unique Local Link Local

14 IPV6 HEADER IPv6 Header Larger Fewer Fields Next Header

15 IPV6 PROTOCOLS ICMPv6, ping6, ping ipv6 Neighbor Discovery (ARP), DAD DNSv6, AAAA DHCPv6, stateful, stateless via RA NTPv4, supports IPv4 and v6 MLDv1 and v2, IGMPv2 IGMPv3 (SSM) Routing Protocols RIPng, IS-ISv6, OSPFv3, BGP4+ Extension

16 IPV6 TRANSITION TECHNIQUES SLB-PT (Enterprise, Content Providers) Tunnels (6to4, ISATAP, Teredo ) 6rd (Stateless) NAT64 / DNS64 Dual-Stack (end game) Lots of Flux, Relatively new Technologies

17 IPV6 TRANSITION TECHNIQUES CGN/LSN/NAT444 IPv4 Content Provider NAT LSN Scoped Address LSN Device IPv4 Internet CGN Provider Network IPv4 Public IPv4 Addresses Consumer NAT IPv4 Clients

18 POLL QUESTION 2 What is the biggest concern in your organization in deploying IPv6? A) Running out of IPv4 Addresses B) Networking Vendor IPv6 Readiness C) Internal IPv6 Operational Experience D) Internal IPv6 Content/Applications
