You will see this URL during console session creation. CloudStack includes the realhostip.com SSL certificate in the console proxy VM. Of course, CloudStack cannot know about the DNS A records for our customers' public IPs prior to shipping the software. CloudStack therefore runs a dynamic DNS server that is authoritative for the realhostip.com domain. It maps the aaa-bbb-ccc-ddd part of the DNS name to the IP address aaa.bbb.ccc.ddd on lookups. This allows the browser to correctly connect to the console proxy's public IP, where it then expects and receives a SSL certificate for realhostip.com, and SSL is set up without browser warnings." |
