Archive for the 'IPv6' category

It’s worth noticing it if you are using Opera. I had a difficult-to-solve issue recently.

While playing with the idea of starting to use IPv6 on my main PC, I tested the waters by validating this option in the network configuration of my Windows XP. Unfortunately, Opera is already fully ready for IPv6 but my router box is not. So, the first effect it had is that Opera decided to enforce the use of IPv6 for all web sites that mentioned IPv6 capacity in their DNS (not many of them, but Google and Free.fr my ISP are already in the list). The immediate effect was that Opera tried to connect to them in IPv6 but failed (because the rest of my home configuration is not 100% IPv6). For 99% of all web sites, there was no difference…

It took me several days (and some Googling – using Safari and Chrome) to understand that this is a known issue and to remove the (still) useless IPv6 Windows configuration.

I’ll have to upgrade my router and try again.

As you certainly already know if you follow regularly this web site, the Internet addresses will soon be depleted (all used). The end of the Internet world as we know it should be reached around 2011 or 2012. That is the reason why some companies are working to push out the most common Internet protocol (IPv4) and to make space for its successor (IPv6).

This is why, while the Internet Engineering Task Force (IETF) was preparing a night without IPv4 to reach the largest possible public, Google launched a version of its search engine reserved to IPv6: ipv6.google.com (If you are like almost everybody, you will not see anything at the end of the link).

Now, we all have to switch as soon as possible.

For most of us, IPv6 has been a little more than vaporware. But in order to fight the upcoming lack of Internet addresses (as IPv4 addresses are more easily known), there is this new protocol, IPv6. It is steadily progressing and tomorrow, February 4th, several of the major international routers of the Internet backbone will start routing IPv6 packets.

It means that IPv6 will become a reality in most regions of the world, even if a lot more is to be done to make it overwhelmingly present.
