Linux DNS Configuration

Linux uses the "/etc/resolv. conf" file to configure the DNS server address. You can use the nameserver configuration item to set the IP address of the DNS server. A maximum of three DNS servers can be used.

$ Sudo VI/etc/resolv. conf

Search localdomain

Nameserver 192.168.1.1

Nameserver 202. xx

Modifications to "resolv. conf" take effect immediately. In the public network environment, we can use the DNS provided by the carrier, for example, 202.106.46.151 and 202.106.0.20.

You can use the NSLookup command to query the DNS server to verify the "resolv. conf" configuration file.

You can use man NSLookup to query specific commands.

So far, the local network configuration for manual Linux series has come to an end.
