To answer your own question - that is precisely why Koenraad thinks
his "addresses will change".

To clarify things :
My dsl-line isn't absolutely stable. Every time the dsl-signal syncs
again, I get a new prefix.
E.g. today I already have received two different addresses :
2a02:a03f:2400:7527:3631:c4ff:fe5c:1427
2a02:a03f:2400:7b80:3631:c4ff:fe5c:1427

That sounds like you may have a problem. Have you contacted your ISP
about this? It's certainly not normal.

What's not normal ? The prefixes, or the instability ?
The prefixes : they want money to have a fixed prefix.
The instablility : long story.


The instability that may also be causing your address issues. One
reason for changing addresses on IPv4 was the shortage of addresses.
So, drop an idle system and give the address to someone else. Then when
the first is working again, give it an address, any address.

With IPv6, there is no such shortage. In fact, some advocate ISPs
handing out nothing smaller than a /48. There are enough /48s to give
every person on earth well over 4000 of them and that with 3/4 of the
IPv6 address space not being allocated for anything.

Bottom line, there is no valid reason for an ISP to keep changing prefixes.
