Does LWIP support DNS over TLS (IDFGH-6743) #40

Closed shun-dgut closed 2 years ago

david-cermak commented 2 years ago

Hi @shun-dgut

You mean DNSSEC as defined in rfc4033? No, I'm not aware of any lwip implementation. Or did you mean some kind of carrying the DNS over (d?)tls? The only option I could think of is to implement an external resolver and add it to lwip's DNS module using LWIP_HOOKs.

Thanks. This could be perhaps a little easier to implement, but unfortunately, the same story, not supported.
