This is mobile phones dominating that number. Almost every 4G / 5G phone right now uses a dual stack IPv4/6 connection. This is not necessarily problematic but home broadband is still lagging by a lot. I sometimes never get a prefix assigned. I have to redial PPPoE as IPv6 link uses IPv4 session. It's not plug and play for home broadband unless you use their modem router combo which has other issues.

That's interesting, thanks for sharing. I thought it is just the other way around.
