📌 How to Set a Static IP on a VPS: Step-by-Step Guide

Using a static IP address on a VPS is essential for stable operation of web services, application servers, remote access, and more. Unlike dynamic IPs, a static address doesn't change after reboot and remains constant. This article explains how to assign a static IP address on popular operating systems.

💡 Why Use a Static IP?

• 📶 Reliable connection without IP changes;
• 🔐 Easier DNS and SSL certificate configuration;
• 🛠 Ability to create consistent firewall, NAT, VPN rules;
• 🎯 Required for apps needing precise IP access;
• 📡 Convenient for SSH, FTP, and RDP access.

🖥 Setting Static IP on Linux (Ubuntu/Debian)

Most modern systems use Netplan. Open the configuration file:

sudo nano /etc/netplan/01-netcfg.yaml
  

Example configuration:

network:
  version: 2
  ethernets:
    eth0:
      dhcp4: no
      addresses:
        - 192.0.2.10/24
      gateway4: 192.0.2.1
      nameservers:
        addresses: [8.8.8.8, 1.1.1.1]
  

Apply the changes:

sudo netplan apply
  

🪟 Setting Static IP on Windows Server

1. Go to Network Connections → Adapter Settings.
2. Find IPv4 Protocol and open its properties.
3. Choose Use the following IP address and enter:

• The IP address assigned by your hosting provider;
• Subnet mask (typically 255.255.255.0);
• Gateway address;
• DNS servers: 8.8.8.8 and 1.1.1.1.

After saving the settings, restart the network adapter. Your server will now use the same IP address consistently.

🧠 Tips and Recommendations

• 📋 Make sure the IP belongs to your VPS and doesn’t conflict with others;
• 📶 Check server availability after applying the changes;
• 🔄 Update your firewall rules if the IP was changed;
• 🔒 Use a DNS name if IP change is possible in the future;
• 🔁 If issues arise — restart the network interface or the server itself.
