title: How to let google domains DynamicDNS to update ipv4 instead of ipv6 for Raspberry pi3
body: <p>I am trying to setup personal Web Server on my Raspberry Pi3, I bought domain from Google Domains so that I could use the Dynamic DNS to let google could update IP Address of my Raspberry-Pi webserver (because my ISP provides Dynamic IP). </p>
  
  <p>On my Raspberry Pi I am using crontab for periodic update by using the wget command as recommended by google. This is the 'syntax' (as adviced by google) what I am using to get the DNS update done: 
  <code>wget https://username:password@domains.google.com/nic/update?hostname=subdomain.yourdomain.com</code></p>
  
  <p><strong>The Problem!</strong>
  Google communicates well and updates my IP but it brings up the IPv6 instead of IPv4 address of my Raspberry Pi. </p>
  
  <p><strong>Question</strong>: What changes should I make on my Pi so that google updates itself with my public IPv4 address rather than IPv6. Kindly note that I am a beginner, so please provide the steps I could easily follow</p>
  
  <p>A big thank you!</p>
