It nicely grabs a list of all the IP (v4 and v6) addresses on the local machine and adds them to a drop down box so you can quickly check your own subnets, or just clear the address box and type in your required range.
While at this time it doesn’t actually “Subnet” IPv6 ranges for you, it does have the handy function of telling you what standard each address on a machine belongs to (or any address you type in) and we all know that /64 should be the smallest range you’re allocating to anything anyway?
I realise I’m doing a lot of this “telling you how to run your network” stuff today, but I’m a big fan of the standards defined for IPv6 and they make everyones job easier if you stick to them!
