How to Set Up IPv6

Prerequisites

Before setting up IPv6, make sure you have:

• SSH access to your VPS
• IPv6 address assigned by Hostxpeed (check service details page)
• Root or sudo privileges

Step 1: Check if IPv6 is Already Enabled

Connect to your VPS:

ssh hxroot@YOUR_SERVER_IP -p 22

ip addr show | grep inet6

Step 2: Find Your IPv6 Details

In Hostxpeed client area (Service Details page), look for IPv6 address (e.g., 2607:5300:205:200::4b93).

Step 3: Configure IPv6 (Ubuntu/Debian Netplan)

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

Add IPv6 configuration:

network:
  version: 2
  renderer: networkd
  ethernets:
    eth0:
      addresses:
        - YOUR_IPV4/22
        - "YOUR_IPV6/64"
      gateway6: YOUR_IPV6_GATEWAY

Apply:

sudo netplan apply

Step 4: Test IPv6 Connectivity

ping6 -c 4 google.com

curl -6 ifconfig.co

Step 5: Configure Services for IPv6

Nginx example (listen on both IPv4 and IPv6):

server {
    listen 80;
    listen [::]:80;
    server_name example.com;
}

Apache example:

Listen 80
Listen [::]:80

Step 6: Update Firewall for IPv6

For UFW:

sudo ufw allow 80/tcp
sudo ufw allow 443/tcp

UFW handles both IPv4 and IPv6 automatically.
