🌍 How to Change DNS on Your VPS

Correct DNS configuration ensures stable and fast domain resolution. While default DNS settings are provided by the hosting provider, you can manually switch to faster or more secure options like Google DNS or Cloudflare. This guide covers how to change DNS settings on both Linux and Windows VPS.

💡 Popular Public DNS Servers

• 📡 Google DNS: 8.8.8.8 and 8.8.4.4
• ⚡ Cloudflare DNS: 1.1.1.1 and 1.0.0.1
• 🔒 Quad9 DNS: 9.9.9.9 and 149.112.112.112
• 🛡 OpenDNS: 208.67.222.222 and 208.67.220.220

🐧 Changing DNS on Linux (Ubuntu, Debian)

Edit the resolv.conf file:

sudo nano /etc/resolv.conf
  

Replace its contents with:

nameserver 8.8.8.8
nameserver 1.1.1.1
  

⚠ On some systems, this file may be overwritten after reboot. In that case, configure DNS using netplan or systemd-resolved.

Example using Netplan:

ethernets:
  eth0:
    nameservers:
      addresses: [8.8.8.8, 1.1.1.1]
  

🪟 Changing DNS on Windows Server

1. Go to Network Connections → Adapter Settings
2. Open Internet Protocol Version 4 (TCP/IPv4)
3. Select Use the following DNS server addresses
4. Enter: 8.8.8.8 and 1.1.1.1
5. Click OK and restart the connection

🔧 Verify DNS After Changes

• 🧪 Test resolution: dig bit.hosting or nslookup bit.hosting
• 🔄 Flush cache: sudo systemd-resolve --flush-caches
• 📥 Check DNS performance: dnsperf.com
