Google Over IPv6 Coming Soon

fuzzel writes "Today Google announced Google over IPv6 where ISPs can sign up their DNS nameservers so that their users will get access to an almost fully IPv6-enabled Google, including http://www.google.com, images and maps, etc., just like in IPv4. Without this only http://ipv6.google.com is available, but then you go to IPv4 for most services. So, start kicking your ISPs to support IPv6 too, and let them sign up. Check this list of ISPs that already do native IPv6 to your doorstep. The question that now remains is: when will Slashdot follow?"

Oh, and if you're using 192/8 for a NAT'd network then you might have some problems since most of that subnet is publicly routable, only the 192.168/16 subnet is private.

    If this is too full of 'technical jargon' for you, here are some definition:

    A subnet is a part of a larger network (borrowing some conventions from set theory, the whole network is also sometimes called a subnet, just to be confusing). IP addresses are a string of bits, 32 with v4 and 128 with v6. For routing purposes, each subnet is identified by a subnet mask. The first n bits of an IP address identify the subnet and the last 32-n or 128-n identify the machine on that subnet. When you see something like 10/8, this means the subnet that starts 10.x.y.z, where the first 8 bits identify the subnet. Sometimes the subnet doesn't fit on a byte boundary. The medium-sized private address range is 172.16.0.0/12. In hex, this is AC100000 - the AC1 is the subnet, and all of the zeros ignored until the packet is on the subnet.

    Subnets can be hierarchical. For example the 10/8 subnet might be used by a big site with the 10.1/16 subnet used by one building, 10.2/16 by another, and so on. The first building might use 10.1.1/24 for one floor, 10.1.2/24 for the next floor, and so on. When you send a packet from the second building to 10.1.1.12 it will be routed to the 10.1/16 subnet, then to the 10.1.1/24 subnet, and then delivered within this subnet by ethernet (the router will use ARP to look up the MAC address that corresponds to that IP address and the ethernet switches will handle delivery on the last segment).

    Bak to your question, you can use a publicly-routable address on a LAN, using v4 or v6. This doesn't mean that data will go over the Internet. If both machines are on the same subnet then packets will never make it to the router, they will be delivered by the local ethernet (or whatever) directly. IP routing is only needed when packets go outside the local subnet.

    If you require longer runs, custom lengths may be ordered at the special price of $9,000 per meter, for lengths greater than 20M only. We highly recommend that you do not couple multiple cables together, as there is currently no way of compensating for any fuzziness or wishy-washiness which may be introduced by the coupler. In the future, we plan to offer 100% compatible couplers in the low 5 figure price range.

    Is there something like that for IPv6 so that I don't have to go all the way out to the internet to get back to my file server?

    That actually is a really stupid question, for someone who knows how Internet routing works.

    Very simply, your computer is always configured to know which addresses are "link-local", which ones must go through a gateway, and what the gateway (router) is. So, for your local address, you've probably got 192.168.1.* as "link-local", 192.168.1.1 is your gateway, and everything else is "on the Internet".

    But that's arbitrary. I like to use the 10.0.0.0/8 network, which is also defined as "local", for that purpose. And all of that assumes NAT -- while at college, all computers had their own, real, Internet-routable IP addresses. But of course, if you had two of them hooked up to the same switch, they would be assigned IPs on the same network, meaning they would connect directly to each other, rather than going "out to the Internet".

    So, you'd build a LAN the same way. If you need to protect it from Internet access, you stick a firewall in front of it, not a NAT. And even if it's a real live Internet address, your computer will know it's local...

    But all of that -- what is LAN, and what is WAN, and what is Internet -- that's pretty arbitrary. It's really more about physical lines than any network addressing. Perhaps the truest thing we could say about it is your local switch (or hub, or router) is part of the Internet, so yes, it has to go a few feet "out to the Internet", even if the signal never leaves your house.

    Windows is a 32-bit extension to a 16-bit graphical shell for an 8-bit operating system originally coded for a 4-bit microprocessor by a 2-bit company that can't stand 1 bit of competition.
