Interesting!

It’s more a question of whether I am willing to pay at least 50% more than I’m paying now for a professional (business) plan instead of a typical (private) home plan just for the privilege of getting static IPs. As this is mostly for experimenting and testing I can’t really justify the extra cost. It would be nice if they offered a (reasonably paid) option to add static IPs to their private plans though. > > | - Use dynamic IPv6 addresses (prefixes) and eui64 IIDs > > Seems like the simplest way, especially using the lladdr option.

My thoughts exactly. Thanks for your input! Mike
