Article title: Configure and implement DNS after bind is installed in Linux. Linux is a technology channel of the IT lab in China. Includes basic categories such as desktop applications, Linux system management, kernel research, embedded systems, and open source.
It is found that the host that serves as the DNS server cannot be connected by ping myself.mydomain.
When the host that serves as the DNS server accesses itself through the domain name, ping myself.mydomain.com to fail to connect, and the prompt "unknown host" is displayed. When you ping other machines, you can ping you.mydomain.com.
It is suggested that the bind will resolve the domain name when it finds that it accesses itself through the domain name. The solution is to add the name of the

In order to differentiate each host in the network, a unique address must be assigned to each host. This address is called an "ip address ". However, these numbers are hard to remember, so they are replaced by domain names. When a host needs to communicate with oth

? The answer is yes, yes. That's what I'm going to talk about today. The advanced features of BIND: View query.To configure a view, the main three steps are:
Collects a collection of IP addresses. For example, I now have a collection of 3 IP addresses, so that each collection can access a different address, that is, one IP in a collection provides another result when querying, providing a parse result, and another IP query in another set;
controlled by the NIC. Root is a layered domain tree structure. a dns domain is a branch in the DNS tree structure, which contains many authorized zones ), it is a collection of hosts and IP addresses managed by each authorization unit. what we usually call a domain is actually a zone. For example, to split the URL www.silly.com:
. Com domain
.Silly.com zone
Www is a specific host in the .silly.com reg
