Generally speaking, renting multiple IPS for the station group server is an important means for SEO to optimize the website. By operating multiple websites, they can copy each other. However, when choosing a group of servers, it is necessary to choose a server with more independent IPS, open IP intervals and good performance. This is not easy to find for SEO optimization, but also conducive to improving the user experience of the website.
Secondly, to deal with the IP blocking brought by DDoS attacks to a greater extent, we all know that DDoS attacks are aimed at IP. If the traffic attack is large, the IP will be pulled. At this time, the website will be in a state of knowledge that can not be accessed. If the server has multiple channels of IP, it can be resolved through the domain name, and the domain name points to another IP to ensure that the data can be accessed normally.
