WiFi.hostByName resolves to 255.255.255.255 when should return error

Hi.

I'm having issues with WiFi.hostByName.
The function is returning 255.255.255.255 when trying to resolve google.com.er, which doesn't exists.
It should return error.

The function used internally is dns_gethostbyname.

Can someone else makes some test to figure out is this is an actual issue or is something particularly of my own code.

Thanks!
