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"
short article). There is one descrepcy that I'm sure I won't be the first
to notice it, either:
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).
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!
An IPv6 address includes the 64 bit MAC address.
This was solved years ago: Privacy Extensions for Stateless Address Autoconfiguration in IPv6.
Dewey, what part of this looks like authorities should be involved?
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)
This took 2 seconds.
nslookup
>set q=any
>f.root-servers.org
f.root-servers.org nameserver = ns-int.isc.org.
f.root-servers.org nameserver = slave.sth.netnod.se.
f.root-servers.org nameserver = ns-ext.isc.org.
f.root-servers.org nameserver = ns-ext.vix.com.
ns-ext.vix.com internet address = 204.152.184.64
ns-ext.vix.com has AAAA address 2001:4f8:0:2::13
Ya I want this too..
As a side note, you can get to Slashdot (and google, and CNN etc) via sixxs.net with IPv6 by going here:

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...
