Since IPv6 is happening, we should be prepared. During the deployment of a new accesspoint I was in need of a Unique Local Address. IPv6 Unique Local Addresses basically are comparable to the IPv4 private address ranges. Some sites refer to Unique-Local-IPv6.com, but that is offline nowadays. Others refer to kame.net generator, which is open source and still available yay. But wait, there must be an offline method for this right?
