Hi all, 
who has available code for auto calculate Ipv6 address. My requirement is generate a new ipv6 which are based on increase by step and IP count. 

For example, start IP is 2002::1, step is ::1, count is 10, the result is 2000::10.  Many thanks in advance.

[DKF]: This is really not a great use of the wiki, but it's hard to tell what you want. (IPv6 addresses are in hex.)
======
for {set i 1} {$i<=16} {incr i} {
    lappend ips [format "2002::%x" $i]
}
puts [join $ips ", "]
======

My description is not accurate, let me explain again, we need a procedure which contain 3 variables, startipv6, increaseTime, increaseStep.

For example, the startipv6 is 2000::1, increaseTime is 200, increaseStep is ::1,  the output should be 2000::c8. thanks a lot.

[aspect]:  Perhaps [IPv6 Addresses] will help you build what you need.
As [DKF] observed, this isn't a great use of the wiki:  if the above hint isn't enough to get you going, more interactive help is needed (perhaps a tutor or a coworker? irc?).
I vote for this page's removal by 2015-01-20 when it will be a month old.
