Sign in to your domain management portal, such as GoDaddy.
Select your domain to access its settings.
Open the DNS management page.
Choose to add a new record and select AAAA as the type.
Enter the hostname, your server’s IPv6 address, and set the TTL (Time to Live).
Save the new record.
Many DNS providers in Hong Kong support IPv6. The table below shows two popular options:
Provider | Support IPv6 | Description |
|---|---|---|
Nicsrs | Yes | Offers full compatibility with IPv4 and IPv6, and DNS servers accessible via IPv6 addresses. |
Gandi | Yes | Provides AAAA records for domains to point to static IPv6 addresses. |
Tip: Always double-check your AAAA record entries to avoid connectivity issues for your network.
Adjust Security Groups and Firewalls for IPv6
You must secure your network by updating firewall rules and security groups to support IPv6. Many tools focus on IPv4, so you need to review your configuration for IPv6 traffic. Start by setting your firewall to deny all incoming IPv6 connections by default. Then, allow only the necessary ports for your applications.
Rule/Measure | Description |
|---|---|
Deny all incoming connections | Block all incoming IPv6 traffic unless explicitly allowed. |
Use personal firewalls | Ensure your firewall supports IPv6 and verify its configuration. |
Disable default IPv6 settings | Turn off unused IPv6 settings to prevent unauthorized access. |
Use encryption | Protect sensitive data with SSL or similar encryption technologies. |
Cloud environments in Hong Kong require explicit configuration for IPv6 security groups. You should:
Set rules for both IPv4 and IPv6 to protect your network.
Identify and secure all IPv6 endpoints.
Treat tunnels with caution and filter traffic at tunnel endpoints.
Note: Attackers may target IPv6 traffic because some security tools overlook it. Always review your network defense for both protocols.
By updating your DNS and firewall settings, you ensure your servers and network support IPv6 securely and reliably.
Test and Verify IPv6 Connectivity
Use Online IPv6 Testing Tools
You need to test your website on ipv6 to confirm that your network supports ipv6. Online tools help you check if your configuration works as expected.
