IPv6 is Here

shawn(at)fsu writes "Reuters is running a story that Vinton Cerf of the Internet Corp. for Assigned Names and Numbers (ICANN) says that "IPv6 been added to its root server systems" I like how they said that it will run along side IPv4 for 20 years to get rid of the bugs. A few previous Slashdot stories out of many here, here and here"

  1. A brief and redundant article by Bold+Marauder · · Score: 3, Informative
    Really doesn't say much that slashdotters don't already know (it's a very

    short article). There is one descrepcy that I'm sure I won't be the first

    to notice it, either:

    Rapid growth in the use of the World Wide Web has in recent times

    prompted concerns about future scarcity of domain addresses, with

    demand threatening to overload the existing system, the IPv4.


    Now, I could be wrong; but my understanding was that the need for IPv6 comes from the scarcity of IP addresses (eg 12.34.56.78) not the scarcity of domain names (eg slashdot.org, slashdot.net, slashdot.jp).

      The term domain addresses refers to IP addresses, not domain names.

    I would suggest you check this out.

    You can have a whole octet to yourself right now. That's a lot of IP addresses and you're ISP doesn't have to support IPv6, it can be encapsulated in IPv4. There are plenty of gateways out there that will translate the request for you so that only your router will need both IPv4 and IPv6.

    It's all up on FreeNet.

    Not too many people remember v5. The IP version is a reference to the IP header "version" field, and 5 was reserved for ST2: See RFC 1819 Sesion 1.2, 2nd paragraph.

    So what do you call the next IP version? Version 6, of course!

    Better still, bring back the old BOOTP protocol? Which if I'm not mistaken just simply keeps a database of MAC addresses to IP Addresses (manually entered),

    An IPv6 address includes the 64 bit MAC address.

    Sometimes, although your source doesn't list that as as requirement. From the page you linked:
    It is recommended that it be used as 16 bit internal network number and 48 bit MAC address, although sites can do what they liked.
    For example, I get a /64 netblock from my IPv6 provider, but I split that out locally to three /80 subnets (LAN, DMZ, and WLAN). Everything I've read indicates that using the MAC address to autoconfig prefixes longer than /64 is impossible, so I have to manually specify the last 48 bits of the IPv6 address on each machine. Fortunately, that means that one host on the LAN is ::2, another is ::3, and so on.

    IPv6 works in a very different way from IPv4, there is no need for private use networks. Each device on a network gets not one, but a few addresses, you have your loopback (::1), but you also have your link local (FE80::/32 an address that's unique in your network but doesn't get routed outside of it) and you can use this for many of the same things you use private addresses in IPv4. Oh, yeah, you also get a multicast address (FF02:/32 that other nodes and the router can use to find your MAC address). That's on top of a bunch of other addresses you may be listening to depending on what you are on the network (dhcp, router, etc)

  10. Re:IPv6 address per-connection? by j+h+woodyatt · · Score: 3, Informative

    Does anyone have a link to this information?

    Look at the latest draft of RFC 2462. Nodes are allowed to use a EUI-64 address for the host number, but the recommendation for stateless autoconfiguration is to generate a unique number and test for duplicates with neighbor solicitation. You don't have to use a MAC address with stateless autoconfiguration, and furthermore you don't have to use stateless autoconfiguration if you use a DHCP server on your IPv6 network.

    On the other hand, some of the docs I've read say the IPv6 address is based on your MAC.

    You haven't read the docs in a long time...
