Understanding IPv6

Springer | ISBN: 0387254293 | 2005-05-19 | PDF (OCR) | 279 pages | 12 Mb

IPv6, Internet Protocol  Version 6, is the next-generation internet protocol designed by the  IETF to replace the current IPv4, now nearly 20 years old. As the new  IPv6 protocol replaces IPv4, professionals need a practical and detailed  reference and introduction that explains the new capabilities and  changes. Especially since new and modified features and integration of  additional protocols underpin IPv6, a well-organized overview becomes  even vital. Here readers find a full explanation of what they need to  know to function optimally in the new environment.

Based on the latest  IETF meetings, Understanding IPv6 provides not only the basics but  details on transition and optimization mechanisms, modifications in DNS,  mobile IPv6, and security issues. In addition, Understanding IPv6  explains each topic based on the latest IETF published documents and:  Compares IPv6 and IPv4, e.g., crucial aspects such as protocol and  addressing architecture, expanded address features, modifications of  DNS, and header formats. Clarifies the many related protocols that need  to be mastered in optimizing IPv6, plus core features such as neighbor  discovery, address autoconfiguration, and DHCPv6. Details  internetworking mechanisms and mobility services with many examples and  figures. Devotes full coverage to transition mechanisms, especially  Teredo. Understanding IPv6 is a reference work for graduate level  students, communications engineers and researchers.

Review: more complex, but necessary
Mun offers a detailed  comparison of IPv4 [the current Internet] to the proposed IPv6. The  shortcomings of v4 are explained. Notably of course is the limited  addressing space of 32 bits. But also the lack of an inherent Quality of  Service. v6 fixes both defects.
Attention should be  paid to the migration details. A very practical matter, since there  needs to be as seamless a transition as possible. The average user  should not be burdened. And the sysadmin as little as possible. It may  well be that legacy v4 code and addressing will be with us for a long  time.
Yes, v6 is clearly more complex. But if nothing else, v4 is running out of addresses.
