Why does the same site open on different domains?

Question

Apache HTTP Server

Hello! Can you tell me why I have 2 identical sites open at site1 and site2 dfkids.ru.conf
file:

<VirtualHost *:80>
  
  ServerName dfkids.redcap52.ru
        ServerAlias *.dfkids.redcap52.ru
  ServerAdmin [email protected]
  DocumentRoot /var/www/dfkids
  ErrorLog ${APACHE_LOG_DIR}/error.log
  CustomLog ${APACHE_LOG_DIR}/access.log combined
</VirtualHost>

File 000-default.conf :

<VirtualHost *:80>
  # The ServerName directive sets the request scheme, hostname and port that
  # the server uses to identify itself. This is used when creating
  # redirection URLs. In the context of virtual hosts, the ServerName
  # specifies what hostname must appear in the request's Host: header to
  # match this virtual host. For the default virtual host (this file) this
  # value is not decisive as it is used as a last resort host regardless.
  # However, you must set it for any further virtual host explicitly.
  #ServerName www.example.com

  ServerAdmin [email protected]
  DocumentRoot /var/www/html

  # Available loglevels: trace8, ..., trace1, debug, info, notice, warn,
  # error, crit, alert, emerg.
  # It is also possible to configure the loglevel for particular
  # modules, e.g.
  #LogLevel info ssl:warn

  ErrorLog ${APACHE_LOG_DIR}/error.log
  CustomLog ${APACHE_LOG_DIR}/access.log combined

  # For most configuration files from conf-available/, which are
  # enabled or disabled at a global level, it is possible to
  # include a line for only one particular virtual host. For example the
  # following line enables the CGI configuration for this host only
  # after it has been globally disabled with "a2disconf".
  #Include conf-available/serve-cgi-bin.conf
</VirtualHost>

# vim: syntax=apache ts=4 sw=4 sts=4 sr noet

From my side they are different, on site1 - Apache stub. It is possible that the DNS cache has not been updated since the change of IP on the domain. Try Google DNS (8.8.8.8)
