Problems with IP Version 4

IP Version 6

IP version 6, sometimes called IPng (IP next generation), was designed by the Internet Engineering Task Force to allow the Internet to grow steadily, in terms of both the number of hosts and the total amount of data traffic. Linux version 2.2 and above comes with an IPv6 implementation built in. There are patches available to add IPv6 capabilities to Apache. Windows 2000 did not ship with a built in IPv6 implementation, but Microsoft has an add-on for Windows 2000 available for developer use. IPv6 software is shipped with Windows XP, though it has to be installed explicitly, is not intended for production use, and is not supported by Microsoft. To test if you have IPv6 installed on a Windows XP machine, you can try typing the following at the command-line prompt:
ping6 ::1
For more details, look for the Windows help file ipv6.chm.

IPv6 is installed and enabled by default in Windows Vista, but there are some "issues".

ARIN, APNIC, LACNIC, and RIPE all now accept requests for blocks of numbers for IPv6.

Adoption of IPv6 has been slow, partly because alternative technologies, such as Network Address Translation (NAT), have been used to extend IPv4's address space.

Internet 2

Internet2 (I2) is a not-for-profit consortium aimed at developing advanced Internet technology and applications for research and higher education, working in parallel with the Next Generation Internet (NGI) project of the U.S. government. It represents over 300 member institutions, including universities, corporations, government agencies, and not-for-profits. Intended applications include telemedicine, digital libraries and virtual laboratories. It is not a single separate network, but joins member efforts together.

I2 is helping to develop and test new technologies, such as IPv6.

Funding comes from I2 member universities, corporate members, grants from NSF and other federal agencies and from industry.

The associated Abilene backbone network (a partnership of Internet2, Qwest Communications, Nortel Networks, Juniper Networks, and Indiana University) was upgraded to 10 Gbps in early 2004.

In Canada, Canarie is handling development of advanced national optical networks that interconnect some universities, research centres, and other eligible sites, both with each other and with international networks. CA*net 3 was deployed in 1998. CA*net 4, deployed in 2002, mostly provides connections at OC-192 (10 Gbps). The University of Western Ontario is connected to the Toronto node of CA*net 4.

Web 2.0

Not really a technical term, often denounced as a mere buzz-phrase, and registered in the U.S. as a trademark for "Arranging and conducting live events", this tag has recently been applied to newer developments on the Web, especially the exploitation of more powerful versions of JavaScript and cooperative efforts like Wikipedia.
