There are some scenarios where we want to assign multiple IPs from different VLAN on the same Ethernet card (nic) on Linux servers (CentOS / RHEL).This can be done by enabling VLAN tagged interface. But for this to happen first we must make sure multiple VLANs are attached to port on switch or in other words we can say we should configure trunk port by adding multiple VLANs on switch.
The first Ethernet interface is usually identified as eth0. To configure a DNS server, add the dns-nameservers IP_ADDRESS line under the eth0 configuration: The line dns-nameservers 18.104.22.168 sets up a DNS server with the IP address of 22.214.171.124 as our DNS server (it is a public DNS server from Google).

On modern Linux including CentOS 7, network interfaces have names such as ens33. If your network interface name starts with en, then it’s an Ethernet cable directly plugged in. If your network interface name starts with wl, then it’s a WiFi interface. Note that the FQDN of the host can be supplied by a DNS resolver, by settings in /etc/sysconfig/network, or by the /etc/hosts file. The default setting of hosts: files dns in /etc/nsswitch.conf causes the configuration files to be checked before a resolver.
