The service I offer allows users who have created an account to have their own page and link it to a domain name purchased from a registrar by using my DNS servers. This is similar to the approach taken by website designers or blog services.

For example, a user with the address myservice.com/tom could link their page to andreyblog.ru by entering my DNS servers at the registrar. Once this is done, their page at myservice.com/tom can be accessed at tomblog.com.

In terms of implementation, it may be possible to make a simple variation on a virtual hosting setup, but it could also require a VDS. To solve the problem, you would need to raise your DNS server and configure it accordingly.

To configure the DNS server, you will need to install and set up BIND on an SQL database such as MySQL. Furthermore, you will need to generate the necessary text configurations for BIND or another DNS server. These configs should ensure that any request for a domain is directed to the list of IP addresses belonging to the service.

It's important to note that the slave server needs to be configured in the same way as the master. Therefore, you cannot generate a master without ensuring the slave takes zones from the master's list.

On the web server side, if you are using VPS/VDS/collocation/dedication, there are several ways to generate virtual host configurations for Nginx, Apache, and other web servers. You can also create default settings for certain scripts and include a directory with a domain in that script.

Additionally, it's worth exploring whether your web server has the ability to include a host in the path address, as this could be helpful for this process. There may be other cases related to this topic that you can also consider.
