khoih-prog / EthernetWebServer

This is simple yet complete WebServer library for AVR, AVR Dx, Portenta_H7, Teensy, SAM DUE, SAMD21/SAMD51, nRF52, STM32, RP2040-based, etc. boards running Ethernet shields. The functions are similar and compatible to ESP8266/ESP32 WebServer libraries to make life much easier to port sketches from ESP8266/ESP32. Coexisting now with `ESP32 WebServer` and `ESP8266 ESP8266WebServer` libraries. Ethernet_Generic library is used as default for W5x00 with custom SPI

FNET dns-client (on Teensy 4.1) doesn't resolve hostnames of Azure Table Storage accounts

This is not an issue of this library but of the FNET library used by the NativeEthernet library on Teensy 4.1.
I'm just searching for people to take part in the discussion whether this is an issue of the FNET library or not.

On the first I would be happy if someone could confirm that on the Teensy 4.1 FNET doesn't resolve the Ip addresses of CNAME records.
Kind regards

@RoSchmi

Thanks for letting us know about the issue. I'm afraid I can't spend time on this issue, but definitely will follow up.

I'm closing the issue now as it's not from this library. Keep us posted anyway.

Regards,

Hi @RoSchmi

Could you please try again using QNEthernet library ?

In case you haven't tried it, have a quick look at this very good New lwIP-based Ethernet library for Teensy 4.1

Major Releases v1.6.0

  1. Add support to QNEthernet Library for Teensy 4.1 built-in Ethernet
  2. Update examples with new features

Thanks @khoih-prog,
in the meantime this issue of the FNET library has been fixed in the vjmuzik/FNET fork.

Today I tried to run my application with the QNEthernet library and it seems to work flawlessly. There are no problems resolving the Azure Storage url.

Thanks and Regards @RoSchmi

You're so fast to release that new repo. to support QNEthernet.

I was impressed with the robustness and stability of the new lwip-based QNEthernet, and decided to port many libraries to use it.

Check the status at New and Modified Libraries to support Teensy 4.1 QNEthernet

I believe you also can help promote this new QNEthernet library so that the lib's author Shawn Silverman will make many more improvements and other users can have this alternative.
