Configure IPv6 on GreenCloud VPS
GreenCloud VPS machines should support IPv6 across the board. Currently, newly opened machines are assigned only IPv4 by default. To add IPv6, you need to manually configure it in the "SolusVM Control Panel."
After logging into the SolusVM management panel, locate your machine and click "Manage - Network - Manage," as shown below.

Once inside, you will find an "Add IP" function. Enter the IP suffix manually, such as :8 or :a (note the : colon!).

You can add multiple suffixes, but testing suggests only the first one at the top takes effect. After adding, return to the management panel and click the "Reconfigure Networking" button to automatically reset the network (note: the machine will restart).

Testing
After the machine restarts, enter the ip a command to view the newly added IPv6 address.

Run the following commands to test if IPv6 network access is working properly:
# Get the outbound IPv6 address
curl v6.ip.rss.ink
# Or enter
curl -6 ip.sb
If both commands fail, your network may not support IPv6. If successful, you can proceed to test connectivity using ITDOG's IPv6 Ping tool: https://www.itdog.cn/ping_ipv6/. If the ping test is normal, everything is working correctly.

Conclusion
- GreenCloud VPS assigns only IPv4 addresses by default; IPv6 must be added manually via the SolusVM panel.
- The SolusVM panel allows adding multiple IPv6 addresses, but only the first one at the top takes effect in practice.
- After adding IPv6, you must click "Reconfigure Networking" to apply the changes.
- Use
curl v6.ip.rss.inkto retrieve the machine's outbound IPv6 address. - Use "ITDOG IPv6 Ping" to verify IPv6 network connectivity.
