This article shows you that there is only one ip in the virtual host, which is concise and easy to understand, which can definitely brighten your eyes. I hope you can get something through the detailed introduction of this article.

In theory, a virtual host can have multiple IP addresses, not just one. Virtual host is to divide a certain disk space on the network server for users to place sites, application components, etc., to provide the necessary site functions, data storage and transmission functions. The IP of the virtual host usually corresponds to the IP of the server, or you can purchase a separate IP to bind the virtual host.

Because of its high performance-to-price ratio, easy to operate, ready-to-use, convenient management and other advantages, virtual host is widely loved by webmasters and has been used in website construction. But at the same time, virtual hosts also have some problems, such as multiple virtual hosts share the corresponding IP of this server, lack of guarantee in terms of speed access and security, and are easily affected by other virtual hosts. If there is a separate IP corresponding to the virtual host, the risk can be reduced.

If there are multiple IP, all pointing to a virtual host, then the advantage will be more obvious. For example, when a website is attacked, the virtual host can be parsed to another IP immediately, so as to avoid the attack and prevent the website from downtime.

So why do many virtual hosts still use only one shared IP? This is mainly due to the depletion of ipv4 resources and a sharp decline in idle IP addresses, which also causes the price of independent IP to rise. For many individual webmasters or small and medium-sized enterprises, the cost is too high. As a result, many cloud service providers have gradually withdrawn the purchase of independent IP services by virtual hosts.

So how can we implement a virtual host to configure a separate IP or multiple independent IP? Waiting for the popularity of IPv6.

Ipv6 with a lot of resources, due to technical reasons and popularity reasons, can not be widely used for the time being, such as 5G mobile phone, which needs a gradual replacement process. When ipv6 is popular and the technology is more mature, then each of our virtual hosts may be equipped with a separate IP, or even multiple IP.

The above is that there is only one ip in the virtual host. Have you learned the knowledge or skills? If you want to learn more skills or enrich your knowledge reserve, you are welcome to follow the industry information channel.
