title: How to create a subdomain at freenom.com?
body: <p>I created a domain at freenom.com 
  <a href="https://imgur.com/a/ClaXVLX" rel="noreferrer">https://imgur.com/a/ClaXVLX</a>
  which points to my app at Digital ocean droplet.
  and next day I created this domain I tested and it works.
  that domain is 1) at printscreen above.</p>
  
  <p>Now I want to create several subdomains, as I know that is possible to make:</p>
  
  <pre><code>site.com - domain
  dev1.site.com, dev2.site.com - subdomains
  </code></pre>
  
  <p>But I do not know what must be entered in fields 2) and 3) ?</p>
  
  <p>When I tried as at printscreen above I got error :</p>
  
  <pre><code>Error occured: Invalid value in dnsrecord
  </code></pre>
  
  <p>Which are valid values ?</p>
  
  <p>Thanks!</p>
