# The above is set as a positive solution. If the forward solution domain name to be set has been registered as a valid domain name, there is no need for reverse resolution settings. In general, the forward and reverse resolution settings must appear in pairs, the following is anti-solution settings

Zone "1.168.192.in-addr. arpa" {// The LAN segment is 192.168.1.0/24,. in-add.arpa is required

Type master;

Sudo cp/etc/bind/db. local/etc/bind/db.example.com // use an existing domain file as the template

6. Introduce the confusing characters in the above configuration file

@: Refers to the content in the double quotation marks corresponding to the zone statement in name. conf. option, for example, zone "example.com". @ in db.example.com refers to example.

SOA: this is the meaning of the content set by Start of Authority.

IN: The meaning of English in. Here is the meaning of "corresponding ".

NS: Abbreviation of name server

A: Positive Solution symbol. The so-called positive solution is to query the IP address "192.168.1.254" based on the domain name "dns.example.com"

PTR: Indicates reverse decoding. The so-called reverse decoding is to query the domain name "dns.example.com" based on the IP address "192.168.1.254"

Note: During the configuration process, the local DNS needs to be cleared. Otherwise, the operation fails.
