My ISP gives me a /48 for home use. I do think the advisce nowadays is
to issue a /56 or /52 or so for home use.

Just by accident I learned today that the Matomo/piwik anonymyzer plug
in has three settings, for 4 /8, /16, /24 which goves for for v6 to
/64, /80, /104. (See https://github.com/matomo-org/matomo/issues/3710
for discussion and
https://github.com/matomo-org/matomo/commit/c072a0e5911b544890a39e86c9efe024bb247577
for the implementation).
