Interspace Cloud offers a comprehensive toolkit designed for the efficient management of private IP addresses on your cloud servers. To access these tools, sign into the My Interspace control panel, select the service associated with your server, and then navigate to the IP addresses/Network tab.

1.Private IPv4 Address Setup

The private IPv4 addresses enable isolated communication between servers, ensuring traffic remains within your private network without exposure to external networks, enhancing security and performance.

The use of private IPv4 addresses within the Interspace Cloud platform is free of charge, with no limits on traffic between servers in your private network. This offers a cost-effective solution for creating secure, scalable, and efficient cloud environments tailored to your specific needs.

To add a private IPv4 address to your server, click Add private IPv4 address. You will be prompted to either select an existing private subnet or create a new one by providing an IP address and a netmask.

The IP addresses/Network tab displays a tabular list that includes detailed information and management tools for the assigned private IPv4 addresses. This list offers functionalities such as the removal of an IP address and the changing the IP address with another one. The details provided for each IP address include: IP address, Netmask, Subnet, and the MAC address of the virtual interface. The MAC address of the virtual interface displayed here is particularly useful as it helps you to uniquely identify the specific interface within your operating system, allowing you to configure the correct interface.

When configuring a private IPv4 address, you must manually set the network settings within your server's operating system. This includes specifying the IP address and subnet mask. You can find theses details in the tabular list mentioned above.

Unlike public IP addresses, there's no support for reverse DNS setup for private IPs. While our DHCP server works only for public IP addresses, you can also setup your own DHCP server on a server dedicated for this purpose, within your cloud private network, and simplify the allocation of private IPs to your servers.

2.Setup Multiple Private IP Addresses on a Single Server

Follow these steps to add additional IP addresses to a single network interface in Windows and some common Linux distros.

2.1.Setup Multiple IPs on Windows

• Open Network Connections: Navigate to the Control Panel, click on "Network and Sharing Center," and then select "Change adapter settings" on the left. Right-click the network adapter you wish to configure and choose "Properties."
• Access TCP/IPv4 Properties: Locate "Internet Protocol Version 4 (TCP/IPv4)," select it, then click the "Properties" button.
• Open Advanced TCP/IP Settings: In the TCP/IPv4 properties window, click the "Advanced" button to access additional settings.
• Add Additional IP Addresses:
  • In the "Advanced TCP/IP settings" window, under the "IP Settings" tab, you'll find the list of IP addresses currently assigned to your adapter.
  • Click "Add" under the "IP addresses" section to enter a new IP address and subnet mask. After entering the details for your new IP address, click "Add."
• Repeat for Multiple IPs: If you need to configure more than one additional IP address, repeat the previous step for each new address.
• Close and Save: After adding all necessary IP addresses, click "OK" on each window to save your settings.

Please see the screenshot below as a reference for the configuration layout. Please note that the IP addresses in the image are samples and should be replaced with your actual allocated IP addresses.

2.2.Setup Multiple IPs on Linux Debian/Ubuntu

• Edit the Network Interfaces File: Open the /etc/network/interfaces file:
  sudo nano /etc/network/interfaces
• Add the Additional IP Configuration: Add the following lines for each additional IP address:
  auto eth0
iface eth0 inet static
address X.X.X.1/24
iface eth0:0 inet static
address X.X.X.2/24

• Restart Networking: Apply the changes by restarting the networking service:
  sudo systemctl restart networking

2.3.Setup Multiple IPs on Linux RHEL/CentOS/AlmaLinux/Rocky

• Edit the Network Script: Open the network script for your interface, typically found at /etc/sysconfig/network-scripts/ifcfg-[INTERFACE_NAME]:
  sudo nano /etc/sysconfig/network-scripts/ifcfg-eth0
• Add the Additional IP Configuration: Add the following lines for each additional IP address:
  DEVICE=eth0
BOOTPROTO=static
IPADDR=X.X.X.1
PREFIX=24
ONBOOT=yes
DEVICE=eth0:0
IPADDR=X.X.X.2
PREFIX=24

• Restart Networking: Apply the changes by restarting the network service:
  sudo systemctl restart network
