ESP32 force other DNS than opendns

Hello,

OpenDNS have been blocked in France since 28 june 2024 and I have some ESP32 expressif chip linked with a STM32.
the IP 208.67.222.222 (OpenDNS IP) seems to be the default DNS IP.
I don't find where I can delete this IP and choose others, like google or quad9, ...

We use ESPWROOM32_setDNS which works but if we reboot or we lose connections, the DNS will be back on OpenDNS.

This OpenDNS IP is it fixed on the esp memory ?

Somebody can help me please ?

thanks in advance ;)

Normally, the ESP32 receives info like that from the DHCP server. In other words: check whatever device acts as the DHCP server on your network.
