Yes, the IPs of the station group servers can be online at the same time. A site server is a group of interrelated and collaborative servers used to host and manage multiple websites. Each website will be assigned an independent IP address, so that multiple websites can run on the same server and share resources.

　　Station group servers usually use load balancing technology to distribute traffic to different servers or virtual hosts to achieve higher performance and reliability. This means that the server can handle requests from multiple websites at the same time, and each website has an independent IP address, allowing it to exist independently on the network.

　　Through the site group server, website administrators can centrally manage and monitor multiple websites to facilitate resource sharing and unified maintenance. The IP addresses of the site group servers are online at the same time, ensuring that each website can be accessed independently, providing stable services and a good user experience.

　　It should be noted that the performance and resource configuration of the site group server need to be planned and configured according to actual needs to ensure that each website can obtain sufficient resources and bandwidth to handle the traffic. At the same time, it is necessary to ensure the security and stability of the server and take appropriate security measures to protect the data and user information of each website.

　　In summary, the IPs of the site group servers can be online at the same time. Through load balancing and resource sharing, multiple websites can be run on the same server. This architecture can improve performance and reliability, and facilitate website management and maintenance.
