World IPv6 day, all the sixes...

Pv6 service trials, June 6

It is too soon to say whether it is a day to change the World, but there is sure to be Global interest in the events of the 6th June 2011 across the net.
IPv6 is set to deliver a 128-bit internet address field, compared to the 32-bits available using IPv4. These extra bits are necessary due to the massive uptake of the internet and also because of the future potential that will be unleashed by 3GPP systems.
A major brake on the early adoption of IPv6, so far, has been the incompatibility of network equipment for IPv4 and IPv6. However, the time is fast approaching where networks must migrate, due to the exhaustion of IPv4 addresses available for use.
The IPv6 Forum and others have warned that we are in the last year of the IPv4 era, and it now appears that IPv6’s time has finally come. The Internet Society has called for a ” World IPv6 Day” on the 6th June 2011, when the major internet providers will launch IPv6 services for one day – “...so that people can help evaluate and troubleshoot the linkages”.
According to Richard Quinnell, in his Everything LTE blog; “Today’s new smartphones and LTE user equipment should already have software in place to work with IPv6, but the rest of the wireless network infrastructure – including third-party website and applications providers - may not. It might be worthwhile to check things out this June to make sure you’re completely ready for IPv6.”

The IPv6 Forum President has recently added his voice to support immediate move of services to IPv6, in a recent Press release Latif Ladid proclaimed “The time is now! And resistance is futile... as the Internet Assigned Numbers Authority has allocated the last IP address blocks from the global IPv4 central address pool, ending all debates over when this would happen.”
The IPv6 Forum (http://www.ipv6forum.com/) is a Market Representation Partner (MRP) in 3GPP.

RFC 4330:Simple Network Time Protocol (SNTP) Version 4 for IPv4, IPv6 and OSI

Simple Network Time Protocol (SNTP) Version 4 for IPv4, IPv6 and OSI

This memorandum describes the Simple Network Time Protocol Version 4 (SNTPv4), which is a subset of the Network Time Protocol (NTP) used to synchronize computer clocks in the Internet. SNTPv4 can be used when the ultimate performance of a full NTP implementation based on RFC 1305 is neither needed nor justified. When operating with current and previous NTP and SNTP versions, SNTPv4 requires no
changes to the specifications or known implementations, but rather clarifies certain design features that allow operation in a simple,stateless remote-procedure call (RPC) mode with accuracy and reliability expectations similar to the UDP/TIME protocol described in RFC 868.

This memorandum obsoletes RFC 1769, which describes SNTP Version 3 (SNTPv3), and RFC 2030, which describes SNTPv4. Its purpose is to correct certain inconsistencies in the previous documents and to
clarify header formats and protocol operations for NTPv3 (IPv4) and SNTPv4 (IPv4, IPv6, and OSI), which are also used for SNTP. A further purpose is to provide guidance for home and business client
implementations for routers and other consumer devices to protect the server population from abuse. A working knowledge of the NTPv3 specification, RFC 1305, is not required for an implementation of
SNTP.
