Just a /64?

 TK> Static is always nice. ;)

My fibre provider gives me a "persistent" IPv6 prefix. Technically it is not static, it is dynamic, but they say by making it "persistent" they follow best practice. It does not chance as long as the router does not change. And indeed it has not changed since my last router change.

My coax provider offers a dynamic IPv6 pefix. It does not change very often, once or twice a year, but there is no discernable pattern. Sometimes  with a firmware update but also sometimes without any traceable trigger.


Cheers, Michiel
