How to build and provision our ISPConfig3 server and how to secure our control panel, main services and websites with Let's Encrypt SSL (page 3) | Linux portal
With the help of the ISPConfig control panel, we can easily manage the websites on our server, as well as other web services. In this description, we will review how to build and provision our ISPConfig3 server, as well as how to set up free SSL certificates issued by Let's Encrypt for the control panel, main services and our websites. On this page, we check the web services and other components running on the server, then we set up the Let's Encrypt SSL certificates for the control panel and the required services and websites. Finally, we perform a few more fine-tuning tasks and eliminate any problems that may arise.

PTR Record | Linuxportal - Encyclopedia
DNS connects domain names (domain names) to IP addresses. The DNS PTR record, otherwise known as the pointer record, provides the domain name associated with the IP address. A DNS PTR record is the exact opposite of an "A" record, which specifies the IP address associated with a domain name.
When a user tries to access a domain name in their browser, a DNS lookup occurs in the background, where the system looks for the IP address associated with the domain name. And DNS PTR records are used in reverse DNS lookups, which is the exact opposite of the normal DNS lookup process: it's a query that starts with an IP address and finds the domain name associated with it.
