Android enforces DNS over IPV6 „first“ to Google Servers as Backup DNS Solution.
Google wants to catch EVERY DNS request for their DNS Logging (Spyware)!
If any IPV6 DNS Google Server answere’s Android stops DNS over IPV4 of LAN to prevent AD’s BLOCKING!!
So no LAN Server is seen on Android Browsers
Solution:
- Disable IPV6 broadcast DHCP/DNS on LAN Routers!
- Block outgoing IPV6 on LAN Firewalls!
With this crap settings google is analysing the whole internet!
