[c-nsp] IPv6 subnetting tools

[Nacho]

Not exactly an online tool, but I think what you're looking for is this:


$ sipcalc 2001:468::/32
-[ipv6 : 2001:468::/32] - 0

$ sipcalc 2001:468::/32 -S /48 | more

Etc, etc.  You get the picture.


It's in most Linux distro repositories (apt-get install, whatever).
