Hi,
supl.vodafone.com is just a CNAME to supl.google.com:
https://dnschecker.org/all-dns-records-of-domain.php?query=supl.vodafone.com&rtype=CNAME&dns=google
I guess the next “best” thing privacy-wise would be agpss.orange.fr.
Without changing this, there is really no use for this module.
Thanks a lot.
