DNS is one of the network infrastructure protocols, presumably everyone should have some understanding. DNS is one of the most important services for all windows-based networks.

In the actual application process may encounter the problem of DNS parsing errors, that is, when we access a domain name can not be completed to resolve the work of the IP address, and the direct input of the Web site IP can be normal access, this is because of DNS resolution failure caused. The probability of this phenomenon is relatively large, so this article will be from the beginning of zero to teach r
DNS server is responsible for the work of domain name resolution, its importance is self-evident. If there is a problem with the DNS server in the network or if the information data is lost, the server will not be able to complete the domain name parsing work. Therefore, you usually want to back up the data information of the DNS server frequently. When a
