IP address change after order restoration

After restoring your order on a dedicated server or a VPS, you may need to reconfigure the network settings manually. Below are instructions for common operating systems and different ways to set up the network.

Ubuntu

1. Open the Console in your order’s billing panel and log in to the server.
2. Run the following command to edit the network configuration:

nano /etc/netplan/00-installer-config.yaml

3. Locate and update the following parameters:

   • Replace the IP address in the addresses field with the value provided in your billing information.
   • Update the gateway in the routes via field with the value assigned to your order.

Example updated file:

network:
ethernets:
eth0:
addresses:
- [your_ipv4_address]/24
- [your_ipv6_address]/48
nameservers:
addresses:
- [your_dns_server]
- [your_dns_server]
- [your_dns_server]
routes:
- to: default
via: [your_gateway_v4]
- to: ::/0
via: [your_gateway_v6]
version: 2

4. Save the changes:

   • Press CTRL + O to save the file.
   • Press CTRL + X to exit the editor.

5. Apply the changes with:

netplan apply

CentOS, Fedora, RHEL (using nmcli)

1. Open the Console in your order’s billing panel and log in to the server.
2. Check the name of your network interface:

nmcli connection show

Example output:

NAME  UUID                                  TYPE      DEVICE
eth0  bb093c6c-944c-34f1-ad26-20ea3c85d995  ethernet  eth0
lo    ae84ba1c-0e92-471e-82a3-f4baa7cb8587  loopback  lo

3. Assign the IPv4 address and default gateway to the interface:

nmcli connection modify 'eth0' ipv4.addresses [your_ipv4_address]/24
nmcli connection modify 'eth0' ipv4.gateway [your_gateway_v4]

4. Save and activate the changes:

nmcli connection up 'eth0'

Expected output:

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

CentOS, RHEL (alternative method via ifcfg-eth0)

On some servers (especially CentOS 6/7 or when NetworkManager is disabled), network settings are configured through files located in /etc/sysconfig/network-scripts/.

1. Open the interface configuration file for editing, usually ifcfg-eth0:

nano /etc/sysconfig/network-scripts/ifcfg-eth0

2. Make sure the file contains the following parameters for a static configuration:

DEVICE=eth0
BOOTPROTO=static
NETMASK=255.255.255.0
ONBOOT=yes
GATEWAY=[your_gateway_v4]
IPADDR=[your_ipv4_address]
DNS1=[your_dns_server]
DNS2=[your_dns_server]

3. Save the changes (CTRL + O, then CTRL + X).

4. Restart the network service to apply the new settings:

sudo systemctl restart network

Debian

1. Open the Console in your order’s billing panel and log in to the server.
2. Open the network configuration file for editing:

nano /etc/network/interfaces

3. Locate and update the following parameters:

   • Replace the value of address with the actual IP address from your billing information.
   • Update the value of gateway with the corresponding gateway.

Example updated file:

auto eth0
iface eth0 inet static
address [your_ipv4_address]
netmask 255.255.255.0
gateway [your_gateway_v4]
dns-nameservers [your_dns_server] [your_dns_server]

4. Save the changes:

   • Press CTRL + O to save the file.
   • Press CTRL + X to exit the editor.

5. Restart the networking service to apply the changes:

systemctl restart networking
