IPv6 Tutorial - Introduction

1. IPv6 Tutorial - Introduction 紀廷運 Louk Chi louk@louk.dyndns.org Executive Secretary in IPv6 R&D division of the NICI Taiwan HSnetwork lab , NTHU

2. Outline • Why we need IPv6 ? • Some info. about IPv6 in the world • IPv6 in Taiwan. • etc

3. Why we need IPv6 ? • It’s simple question : addresses • IPv6 is auto-config • Ipv6 provide security. • IPv6 provide the mobile possibility

4. IPv4 stack Service Type Ver IHL Total Length Identification Flags Offset TTL Protocol Header Checksum Source Address Destination Address Options + Padding 32 bits

5. IPv4 address • Example: 203.68.42.2=1100 1011:0100 1000:0010 1010:0000 0010 • Maximum = 2^32 = 4 Billion • Class A Network: 2^24 nodes • Class B Network: 2^16 nodes or less • Class C Network: 2^8 nodes or less

6. When IPv4 will run out ? • 一項由APNIC所支持的研究 - “IPv4 Address Lifetime Expectancy on July 2003”

7. In IPv4 , how we save the problem? • NAThowever , you must pay a lot of money for multi-NAT.

8. So..ipv6 provide.. • IPv6 Forum • Larger Address Space • Efficient and Extensible IP datagram • Efficient Route Computation and Aggregation • Improved Host and Router Discovery (ND) • Mandated New Stateless and Stateful Address Autoconfiguration • Mandated Security for IP datagrams • Easy renumbering

9. IPv6 stack Ver Flow Label Next Header Hop Limit Payload Length Source Address Destination Address 32 bits

10. IPv6 address • 128 bits (16 bytes) • 2^128 = 3.4×10^38 addresses • Representation 8 unit * 2 bytes • Example 1: A1B2:C3D4:E5F6:7890:9876:5432:1A2B:3C4D • Example 2: 0:0:0:0:0:0:0:1 (LOOP BACK) • Example 3: ::1 (LOOP BACK) • Example 4: :: (UNASSIGNED) • Allows multiple interfaces per host • Allows multiple addresses per interface

11. IPv6 story • 1990年IETF(Internet Engineering task Force) 進行新一代網際網路通訊協定的選擇作業 • 1993年成立IPng Area (IPng：IP The Next Generation)來評估各項建議和技術的可行性以加速協定的制定。 • 1994年CATNIP、SIPP、TUBA這三份IPng建議書最為人所支持。而在1995年RFC1752文件中，比較這三份建議書，經過多方討論廣納意見之後，決定採用SIPP，再加上128位元的位址以及自動設定等功能 • 此時，新一代網路通訊協定(IPv6)的雛形就此誕生。在這之後，陸陸續續又有許多RFC被提出用來規範IPv6相關規格、位址架構、控制協定等標準，讓IPv6更臻完整也造就其蓬勃發展。
