What is the difference between dynamic IP and static IP?

Dynamic IP needs to obtain an IP address automatically for users to access the Internet when connecting to the network. Static IP is the IP address assigned to the user by the ISP or network device. You can connect directly to the Internet without obtaining an IP address. Perhaps the user's understanding of dynamic IP and static IP is still stuck in the concept of obtaining IP or fixed IP, please see below for more information.

should be called a static IP fixed IP, operators gave you a fixed IP will tell you the corresponding mask and gateway, and then you can put the IP configuration in a local area connection, so you boot At that time, there is one less process of obtaining IP, which of course can be ignored. In fact, most of the fixed IP is used for externally released servers. Everyone knows that all the URLs we enter when we hit the webpage are URLs, and the DNS server can know the IP of your server through the URL, thus providing services. If you don't need fixed IP, let the server Always get, then DNS does not know which IP to point your URL, it can not provide services.

The impact of dynamic IP and static IP on the network speed:

The network speed provided by the ISP for each user is not limited by the IP address, but is connected from the user to the ISP. Defined on the physical line. For example, the ISP opened 4M of bandwidth to Xiao Ming's line, but opened 2M of bandwidth to Xiaohong's line. But even if both Xiao Ming and Xiao Hong use static IP, Xiao Ming will have better Internet speed than Xiao Hong. Therefore, from this actual situation, it can be known that the IP address has no effect on the network speed.

Static IP address assigned by ISP

First of all, please forgive me for being a real person. It is impossible for an ISP to give an IP address. Accurately, it should be said that the ISP leases the IP address to the user. Because in the current IPv4 address has been allocated, severely scarce. It is impossible for an ISP to give an IP address to a user.

The difference between static IP and dynamic IP

Why do users with static IP, but not everyone, use dynamic IP to increase the flexibility of IP address usage? Here to talk about DNS. We know that when we want to visit System Home, we enter the website address in the browser: http://www.xitongzhijia.net. However, in the network world, the transmission of data is based on the IP address as the source and destination address, not a website address. At this time, the role of DNS is to translate the website address into an IP address to facilitate the user's memory. Therefore, in order not to constantly update the DNS record, the role of the static IP address appears.

Dynamic IP is not a real IP. The domain name you provide is dynamically assigned by the server for users to access the Internet when they cannot remember the static IP address.

Static IP is an IP segment that can be directly connected to the Internet. When the IP is installed, the IP address will be assigned to you, so that the computer will not automatically obtain the network address when connecting to the network, thus avoiding the trouble of the network connection. .

Static IP and dynamic IP are weak points for each other. When connecting the rest of the network, you do not need to change the IP address to obtain it automatically or to fix the IP address, but the impact is not great. Please remember to back up the static IP address before setting. Easy to access the Internet next time.
