Now, the pings are working, tested to IP addresses and to domain names like. Add 3rd DNS server with IP of the gateway. remove quotation marks from ZONE="trusted" I installed a fresh version of Minimal CentOS 7. change GATEWAY to the gateway IP address shown by my VM using DHCP
change IP address to the IP range shown by my VM using DHCP Then I overtook the settings from /etc/sysconfig/network-scripts/ifcfg-enp0s3 more or less into my VM with fix IP address so that /etc/sysconfig/network-scripts/ifcfg-enp0s3 for the fix IP address looks as follows: Create a file named /etc/sysconfig/network-scripts/ifcfg-eth0 as follows: DEVICEeth0. When a DHCP client requests a DHCP server for an IP address, the DHCP server leases an IP address from a range of IP addresses for a certain time (TTL). In this quick tutorial you will learn about configuring a network interface with a static IP address using ifcfg files located in /etc/sysconfig/network-scripts/ directory in a CentOS 7 and RHEL 7: ADVERTISEMENT. With RHEL/CentOS 8, the ifup and ifdown commands are part of NetworkManager rpm unlike older releases where these were part of initscripts rpm. On the other hand, dynamic IP addresses may change with time. I set my VM with DHCP to fix IP address and tested this. Static vs Dynamic IP Addresses and DHCP: Static IP address is fixed.
