Upgrading the DNS server to improve Internet speed

The speed of surfing the Internet, and DNS server domain name resolution ability is closely related, I hope the internet surfing smooth sailing, we must find ways to ensure that the DNS server efficient and stable operation. To do this, we only have the workaround, dig deeper, and be good at using some of the details of the DNS server to make DNS servers more efficient for us to provide domain name resolution services. The following article set out from six aspects, so that you do not have to spend a cent "upgrade" DNS server productivity.

Use command to achieve rapid management

For a DNS server to function efficiently, it must be set up with appropriate parameters. The most common way to set up DNS is to use the DNS console, and I'm sure you're more familiar with it. But it is not known that the use of humble DOS commands, not only to achieve the goal of rapid management of DNS, but also received unexpected miraculous.

For example, to quickly check if a DNS server has an incorrect DNS resolution record, simply go into MS-DOS and enter the string command "Ipconfig/registerdns" at the command prompt, and click Enter. The DNS server automatically activates the DNS resolution record registration feature. Any error resolution record is automatically saved in the System Event Viewer in 15 minutes, and we will be able to view the DNS server for incorrect parsing records in the future when we enter the viewer.

To see all of the local DNS resolution records at a glance, do not need to open the DNS console window in a step-by-step way to find the appropriate viewing interface, just go into MS-DOS, then enter the string command "Ipconfig/displaydns" on the command line, click Enter, We can see all DNS resolution records in the local host on the results page (Figure 1). In addition, when you want to view detailed configuration information for a DNS server, you can easily implement the "Ipconfig/all" command, which is easier and faster than using the console.

Use log to view DNS status

As you know, whether a Web site can be accessed quickly depends on the DNS server's domain resolution speed, and the resolution of a domain name depends on the working state of the DNS server. Based on the above inference, to improve the access speed of the website, we must check the DNS server's working status in time, once found that DNS has problems, must strive to solve the problem in the first time. How can I get a quick picture of the status information for DNS? With the ability to take advantage of the DNS logs, you can easily view the various state information for the DNS service, which is the next step in viewing DNS status:
