IPv6 Tested in Space

An anonymous reader writes "Remember the Cisco router orbiting on a satellite in space? Well, it's now also the first to run IPv6 in space. Since no-one is choosing to run IPv6 on the ground, isn't this a bit pointless?"

Pointless? No.

If you're going to start putting Interplanetary WAN infrastructure in place, might as well go IPv6 from the get go. Then once there are a few billion nodes scattered about the Solar System we won't have any addressing problems ;)

Re:Gee, why is no one switching to IPv6?

While it is certainly true that there aren't a whole ton of home routers that support IPv6 yet, it's on the way. Vista installs IPv6 by default and it's a pain to get rid of it. Vista tells you you've got full IPv4 connectivity, but limited IPv6 connectivity...and I've already had one client ask me what that meant, and how he could get full IPv6. Folks will buy an IPv6 router just because it's got a bigger number...and now that Vista advertises IPv6 connectivity, people will be aware that there is a bigger number to be had.

Plus, some stupid applications insist on trying IPv6 if it is installed and wait forever for the packets to time out... A common problem I ran into with folks who tinkered under XP was massive slowdowns with Firefox after someone had installed IPv6. Remove IPv6 and everything was fine. Of course...Vista doesn't like it when you try to remove IPv6... Haven't had any calls about slowdowns yet...maybe Vista handles the stack better than XP did...

As far as "no-one is choosing to run IPv6 on the ground"... Well, that's just not true. Many ISPs are running IPv6 on their internal networks. You'll never see it because your modem/router/LAN live in an IPv4 tunnel...but it's there. I know I've seen Job Ads for the local hospital asking for IPv6 experience as well...though I don't know if they're actually using it yet or just preparing for the future.

"Dotted quads" may be easier for you to memorize...but I suspect this is largely because that's what you're dealing with on a day-to-day basis. Remember when you were little and it was hard to memorize addresses or phone numbers? Now that seems incredibly simple, doesn't it? Remember when you were just learning IP and wondered why you couldn't use DNS for absolutely everything (because names are so much easier to memorize than numbers). Plus, IPv6 supports a couple different ways to abbreviate addresses...such as stripping leading 0's or replacing them with :: Which makes our old friend 127.0.0.1 something much easier to remember - ::1

And simply re-allocating the IPv4 address space just isn't going to cut it. There aren't enough addresses out there. The only reason we've been able to stay with IPv4 for so long is NAT, which causes problems of its own. The bottom line is that we need more addresses than IPv4 has.
