Your website is hosted on a highly-available cluster of servers (regardless of your hosting plan) and is associated with two different IP's for load balancing capability (make sure to properly setup your DNS for this to work).
To view the IP's associated with your website:
Navigate to the website overview screen by selecting / clicking on the related card in the Websites overview screen. Tip: You can quickly navigate to a website by using the S keyboard shortcut to bring up the quick search dialog.
On the Domains and SSL section click on CLUSTER IPs to expand the panel and view the IPs associated with your website.
