If you did not configure networking during the CentOS Stream installation, configure it like follows.

Set Hostname

hostnamectl set-hostname dlp.srv.world

Configure Static IP

Display available devices:

nmcli device

DEVICE  TYPE      STATE                   CONNECTION
enp1s0  ethernet  connected               enp1s0
lo      loopback  connected (externally)  lo

Replace enp1s0 with your own interface name.

Set IPv4 address:

nmcli connection modify enp1s0 ipv4.addresses 10.0.0.30/24

Set gateway:

nmcli connection modify enp1s0 ipv4.gateway 10.0.0.1

Set DNS (for multiple DNS, use space separated: "10.0.0.10 10.0.0.11"):

nmcli connection modify enp1s0 ipv4.dns 10.0.0.10

Set DNS search domain:

nmcli connection modify enp1s0 ipv4.dns-search srv.world

Set to manual (static) mode:

nmcli connection modify enp1s0 ipv4.method manual

Restart the interface to apply changes:

nmcli connection up enp1s0

Connection successfully activated (D-Bus active path: /org/freedesktop/NetworkManager/ActiveConnection/3)

Verify Settings

nmcli device show enp1s0

Disable IPv6

If you don't need IPv6, disable it:

grubby --update-kernel ALL --args ipv6.disable=1

Verify kernel parameters:

grubby --info DEFAULT

index=0
kernel="/boot/vmlinuz-6.12.0-32.el10.x86_64"
args="ro resume=UUID=5fa38690-3750-415e-99a3-155a720bc1bf rd.lvm.lv=cs/root rd.lvm.lv=cs/swap console=ttyS0,115200n8 ipv6.disable=1"
root="/dev/mapper/cs-root"
initrd="/boot/initramfs-6.12.0-32.el10.x86_64.img $tuned_initrd"
title="CentOS Stream (6.12.0-32.el10.x86_64) 10 (Coughlan)"

Reboot to apply:

reboot

To re-enable IPv6:

grubby --update-kernel ALL --remove-args ipv6.disable
