When working with the NativeEthernet library which uses FNET as dependency I noticed that certain urls were not resolved.
I opened an issue on butok / FNET but we didn't succeed to achieve a solution.
butok#7
Others like @egonbeermat and @frederic01 (on the teensy forum https://forum.pjrc.com/) had similar problems that urls using aliasis were not resolved.

defragster at the pjrc forum proposed to make a pull request against https://github.com/vjmuzik/FNET
My changes solved the problems for me and @egonbeermat but I propose that the changes are reviewed so that they will not have unforeseen sideeffects.

Try this last commit and see if it resolves this issue for you, I'm finally getting around to doing some improvements and I discovered the UdpNtpClient example from NativeEthernet wasn't obtaining an IP. Of course Wireshark shows that it got something and I remembered this issue so I added some handling for a CNAME record based on what I think should happen with it. Now the example is working so this should presumably fix your issue too.

Thanks, I'll try it in the next days and will give feedback.

I can confirm that with your last commit (be3a67e) and arduinoteensy 1.154 dns resolving of CNAME records works for my application. Thank you.

I'll close this for now, but reopen it if you run into any other urls giving you an issue.
