title: How should a PTR DNS record look like when using default Azure server for reverse DNS?
body: <p>I'm trying to add a PTR record (reverse DNS) in Azure, but I'm not sure what should be the value in the PTR DNS record, My azure settings are:</p>
  
  <blockquote>
    <p>DNS NAME people-dns.cloudapp.net</p>
    
    <p>HOST NAME people-dns</p>
    
    <p>PUBLIC VIRTUAL IP (VIP) ADDRESS 137.117.11.18</p>
    
    <p>INTERNAL IP ADDRESS 100.68.96.97</p>
  </blockquote>
  
  <p>The DNS name points to the mail server...</p>
  
  <p>I understand that I don't need to run any PowerShell commands if I'm using the default DNS name (but maybe I'm wrong?)</p>
  
  <p>I was simply adding a PTR record (using Google Domains) with value people-dns.cloudapp.net for the domain, but I don't know if I need to specify some IP addresses or type it reversed like I saw in <a href="https://stackoverflow.com/questions/621601/setting-up-reverse-dns-records">here</a></p>

  <p>I found out that the PTR record is critical to avoid email rejections from GMail as I'm trying to resolve a problem where email ends up as SPAM for GMail users when they get it for the first time...</p>
  
  <p><strong>Do you think I should add or change anything?</strong></p>
