Subj : This happens when ISPs ignore IPv6 To : Joe Delahaye From : Michiel van der Vlist Date : Sun Feb 21 2016 00:18:37 Hello Joe, On Saturday February 20 2016 16:13, you wrote to Roger Nelson: JD> Sounds good. In the meantime my IPv6 is back online. But your IPv6 address has changed. Your system no longer accepts incoming at 2607:f2c0:f00e:4200:f9e0:b9ff:6166:c8ef. When calling out to me it presents: 2607:f2c0:f00e:4200:5ca2:8378:ffe0:6977, but it does not answer at that address, so that may be a temporary privacy extension address. The odd thing is that it is not the prefix that has changed, only the suffix. So it is a problem local to your system.
