How to Enable and Configure IPv6 on Your Deco

Configuration Guide
Last updated: May 8, 2026

Deco supports IPv6 internet connections, and you can enable Deco IPv6 directly in the Deco App. The connection type you select must match what your ISP provides. If you are unsure which type to use, contact your ISP before starting.

Throughout this guide, we use Deco M5 as an example.

Key Takeaways

  • To enable IPv6 on your Deco, open the Deco App and go to More > Internet Connection > IPv6, then toggle it on and select your connection type.
  • There are four IPv6 internet connection types: Dynamic IP (default), PPPoE, 6to4 Tunnel, and Bridge. Your ISP will provide the correct type and any required credentials.
  • For PPPoE, Deco uses the IPv4 account by default. If your ISP provides separate IPv4 and IPv6 accounts, disable Sync IPv4 Account and enter IPv6 credentials manually.
  • The 6to4 Tunnel connection type requires an active IPv4 Internet connection as a prerequisite.
  • If the Deco connects to another router that provides IPv6 access to all connected devices, use the Bridge connection type.
  • Once saved, check whether your devices show an IPv6 connection.

Note: Before setting up an IPv6 internet connection on your Deco app, please make sure your phone is connected to the Deco network.

Here we take the Deco M5 as an example.
