Whitelist Emails for PhishER

When you create an action in PhishER, you can select the Send Email option to send an email to recipients when the action occurs. To ensure that these emails reach your recipients' inboxes, we recommend that you whitelist KnowBe4's IP addresses. Our current IP addresses are listed below:

Important:These IP addresses are subject to change. This list will be updated with the most current IP addresses available.
  • 23.21.109.197
  • 23.21.109.212
  • 147.160.167.0/26
    Note:"/26" indicates IP range: 147.160.167.0 - 147.160.167.63. If your whitelisting provider doesn't allow for an IP range, each IP in this range will need to be entered individually. For more information, visit Microsoft's TCP/IP addressing and subnetting documentation.
  • 52.49.201.246
  • 52.49.235.189
