Hello narpaw

Regarding a dns-lookup, please refer to the below examples.

  1. DHCP
    Generally, you don’t need to set a dns-server.
AT+WD
[OK]
AT+WM=0
[OK]
AT+WWPA=123456789
[OK]
AT+NDHCP=1
[OK]
AT+WA=Wiznet_Kaizen
    IP              SubNet         Gateway   
 192.168.15.15: 255.255.255.0: 192.168.15.1
[OK]
AT+DNSLOOKUP=google.com
IP:173.194.126.201
[OK]
  1. Static IP
    If you use a static IP for WizFi210, you need to set a dns server manually as below.
    I just used google dns server(8.8.8.8) for a test.
AT+WD
[OK]
AT+WM=0
[OK]
AT+WWPA=123456789
[OK]
AT+NDHCP=0
[OK]
AT+DNSSET=8.8.8.8
[OK]
AT+NSET=192.168.15.111,255.255.255.0,192.168.15.1
[OK]
AT+WA=Wiznet_Kaizen
    IP              SubNet         Gateway   
 192.168.15.111: 255.255.255.0: 192.168.15.1
[OK]
AT+DNSLOOKUP=google.com
IP:173.194.127.227
[OK]

In above your log, you used the static ip, it means that you need to set a dns server like <AT+DNSSET=8.8.8.8>.
