I've set up an ESP8266 (Wemos D1 Mini) to get IP-information via DHCP. Everything works fine and I can print the information :

Serial.print(WiFi.macAddress()); Serial.print(WiFI.localIP()); Serial.print(WiFi.subnetMask()); Serial.print(WiFi.gateway.IP());

But how do I print the DNS-address ??

I cant find a function for this ???

/Kind regards : Gurra

If you have more than one DNS server you can specify the index:

    Thanks Majenko, i've Googled this question and found answers to ip, netmask, mac & gateway but not DNS, so you saved me hours of extra work by this....So I am very grateful !!

    You're welcome. You can find all the functions in the ESP8266WiFiSTA.h header file.
