Remote support with IPv6-only VNC
While looking for a cross-platfrom remote support solution that does IPv6, I ended up using commercial software this time: RealVNC Enterprise Edition. This does some other handy things as well, such as AES encryption, system authentication, and an Accept/Reject dialog on the client.
By default it listens on both IPv4 and IPv6 but it can be easily configured to listen only on IPv6:
I use this to remotely support people. One important issue: you do have to know the network address before you can connect to it 
. There are two ways, users are either:
- In the office. All our computers autoconfigure themselves with the modified EUI64 interface identifier, which is based on the interface's MAC address. This means that computers will have a predictable address in the office. This means that you can assign easy to remember hostname to them 'laptop-alice-wifi', 'laptop-alice-wired', etc.
- Out of the office. People working from remote need to set up their Cisco AnyConnect VPN connection. Once that is done, they have IPv6 connectivity, bypassing any NAT boxes they might be behind. They either need to tell me their network address, or I can look it up on our VPN server.
An alternative for locating machines would be dynamic DNS, but I have not found an end-user-friendly and easy-to-administer cross platform solution for that - yet.
