Several URLs I found

[seemebreakthis]

I made my phone go through Pihole for one night. Here are some additional ones I found:

find.api.micloud.xiaomi.net
g-galleryapi.micloud.xiaomi.net
global.market.xiaomi.com
matrix-pri-alisgp.alb.xiaomi.com
resolver.msg.global.xiaomi.net
us.galleryapi.micloud.xiaomi.net
jupiter.intl.sys.miui.com
i.mi.com
sg.api.io.mi.com

FindApi is required to locate a lost&misplaced phone and global.market is required for updating system apps.
They should be part of the whitelist.

... unless you do not want any of Xiaomi's service - I never use their 'system apps' (like 'security') much less their 'system apps updater', and I use google to find my phone.

Of course to each their own, but for those who only like the Xiaomi hardware and want to avoid your data from getting fetched to Xiaomi as much as possible, then consider blacklisting these names too. Doesn't impact my phone in any way with these blacklisted.
