dns round robin

In the last blog post we introduced several of the most essential records in a DNS server, including A records, NS records, and SOA records. In this blog post we will continue to introduce several other commonly used records of DNS, hoping to help you understand DNS. Four MX records MX records are also known as Mail Exchanger Records, and MX records are used to

Description1, NetworkManager tool is the Ubuntu desktop version of the GUI setup tool.2, this tool is recommended to operate directly on the GUI, it is not recommended to use the command line management, such as WiFi configuration.3, of course, this tool can have command line tools:nmcli, if the use of NetworkManager to configure the network, then IP, gateway, DNS can be queried through this tool.4, if the command line network settings are configured,

the proxy server, the proxy server directly sends the buffered content to the user. If there is no buffer, a request is sent to the WEB server first to retrieve the data, and then the local cache is sent to the user. This method reduces the number of requests sent to the WEB server and the load on the WEB server. Ii. System Architecture 1. Principles DNS round robin technology is used to distribute request

1. The Setup method is very simple. We found "setup" on the phone and clicked on it to enter. 2. Then we click on the set of "Wireless LAN" to find it click to enter. 3. In the Wireless LAN list, click the exclamation point on the right side of the wireless network on which the current phone is connected, as shown in the picture 4. Now we find the following DNS in the DHCP below the IP address in the open interface, click on it. 5. Then we

access the server normally.　　 DNS Server Load balancer uses a simple round-robin load algorithm, which does not distinguish between servers, does not reflect the current running status of servers, and cannot allocate more requests to servers with better performance, client Requests may even be concentrated on a server.　　 Assign an Internet IP address to each server, which will occupy too many IP addresses.
