RE: [U2] IPv6
IPv6 will be a non issue for most even if the potential for problems exists. When introduced I am sure you will find that internal subnets will still run IPv4 with bridges and an appropriate netmask e.g. 255.255.255.255.0.0.

Re: [U2] IPv6
Might I be so bold as to point out that the pictures are misleading? They represent only about 1/4th of the available addresses because they show only class 'a' networks. If they showed a picture of class 'c' networks, the numbers would be staggering, on the side of availability. Can anyone spell 'factorial'? My 2-bits, which makes absolutely no difference in what's actually going to happen. It feels nice to be of so little consequence.

RE: [U2] IPv6
Most *nix platforms have supported both for some time now so you can run either or both depending on your routing hardware and software end-point requirements. I have no clue about Microsoft's mayhem. I hope I don't confuse too many people here. I'm still catching up on the v6 addressing scheme myself. There are two types of IPv6 address that can embed IPv4 addresses: ftp://ftp.isi.edu/in-notes/rfc2373.txt Section 2.5.4 IPv6 Addresses with Embedded IPv4 Addresses 1) IPv6 packet tunneling for IPv4 routing (80-bits of zero)(16-bits of bit zero)(32 bits of IPv4 address) Ex. :::127.0.0.1 2) IPv4-only networks using IPv6 addressing (80-bits of zero)(16-bits of bit 16)(32 bits of IPv4 address) Ex. :::127.0.0.1 You would use #1 for instances where you wanted to use IPv6 packets on a IPv4 network(with IPv6 end-points). #2 is IPv6 addressing for end-points that only accept IPv4 packets. If you deploy IPv6 and still have to use IPv4 on an end somewhere, then you'll need to go with #2. I have several boxen running Debian now that listen on tcp6 stacks using :::addr binding. All of my Windows boxen use IPv4 still, so I haven't had to move to IPv6 completely yet. This transition between 4 and 6 is going to be tough. That's why options #1 and #2 were put into the RFC. IPv6 is 8 segments of 16-bits, which is 128-bit hex addressing more similar to MAC hardware addresses than our familiar numerical IP addresses. ::::::: ::::::: 340,282,366,920,938,463,463,374,607,431,768,211,456 addresses Luckily, the RFC offers sanity to addressing methods using shortcuts which eliminate leading and ending 16-bit blocks of zeros. :: means repeated 16-bit zero blocks. 0:0:0:0:0:0:0:1 can be represented as ::1 (or ::0001 if I'm not mistaken). -- Glen Batchelor IT Director All-Spec Industries phone: (910) 332-0424 fax: (910) 763-5664 e-mail: [EMAIL PROTECTED] --- www.allspec.com --- -Original Message- From: [EMAIL PROTECTED] [mailto:owner-u2- [EMAIL PROTECTED] On Behalf Of Charles Barouch Sent: Monday, May 07, 2007 1:33 PM To: u2-users@listserver.u2ug.org Subject: [U2] IPv6 All, With the US government requiring implementation by June 2006, with Europe and Asia already doing a lot with it, shouldn't there be more talk here about IPv6 (http://www.ipv6.org/)?
