title: Azure agent ip - weekly agents ips list
body: <p>The pipeline I am using is running in organization located in east us 2. I have 2 runs in my pipeline with following agents ips:</p>
  <ul>
  <li>01 september, ip: 20.114.117.102</li>
  <li>02 september, ip: 20.253.217.28.</li>
  </ul>
  <p>And I have 2 files with azure agents ip ranges from <a href="https://www.microsoft.com/en-us/download/details.aspx?id=56519" rel="nofollow noreferrer">https://www.microsoft.com/en-us/download/details.aspx?id=56519</a>:</p>
  <ul>
  <li>ServiceTags_Public_20220822.json;</li>
  <li>ServiceTags_Public_20220829.json.</li>
  </ul>
  <p>Info from: <a href="https://docs.microsoft.com/en-us/azure/devops/pipelines/agents/hosted?view=azure-devops&amp;tabs=yaml" rel="nofollow noreferrer">https://docs.microsoft.com/en-us/azure/devops/pipelines/agents/hosted?view=azure-devops&amp;tabs=yaml</a></p>

  <p>The new IP ranges become effective the following week.</p>

  <p>Luckily I have both files from 22 and 29 august, unfortunately no one matches my ips assigned to azure hosts. Parsing ServiceTags_Public_20220822 I can see that:</p>
  <ul>
  <li>20.114.117.102 matches only southcentralus subnet 20.114.64.0/18;</li>
  <li>20.253.217.28 matches only westus subnet 20.253.128.0/17.</li>
  </ul>
  <p>Above does not make sense, both addresses should match one of cidr ranges from single region, anyone knows where do I make mistake?</p>
