You may have an Axon Ivy Engine deployed in the wild and licenced only the DNS Name as Public URL: But you get licence violations mails, because there are users or crawlers in the world wide web which are acessing the Axon ivy Engine via IP Address.
You can request for a new licence and add the IP Address in the licence, but nobody likes hard coded IP Adresses...
An alternative approach would be to prevent the direct access to the Axon Ivy Engine via IP Address. Therefore you could make a redirect on reverse proxy for this case.
For Apache this could look like that:
RewriteEngine On
RewriteCond %{HTTP_HOST} !^cloud.axonivy.com$
RewriteRule /(.*) https://cloud.axonivy.com/$1 [L,R=301]
