Step-by-Step Guide to Enabling IPv6 on Your Network with Cogeco ISP and UniFi

In today’s rapidly expanding digital landscape, IPv6 is becoming increasingly critical for ensuring efficient and secure internet connectivity. Whether you’re managing a small home network or administering the infrastructure for a small business, making the transition to IPv6 can significantly improve your network’s scalability and performance. For Cogeco ISP users with UniFi networking equipment, enabling IPv6 is a straightforward process. Here’s a step-by-step guide to get you started.

Step 1: Access WAN Settings to Enable DHCPv6

Your first step involves accessing the WAN (Wide Area Network) settings within your UniFi Controller. This is where you’ll enable DHCPv6, which is crucial for your network to communicate over IPv6.

  1. Login to UniFi Controller: Open your browser and enter the IP address of your UniFi Controller. Log in with your credentials.
  2. Navigate to Settings: Once logged in, look for the ‘Settings’ option in the left-hand menu and click on it.
  3. Access WAN Settings: Inside the Settings menu, find the ‘Networks’ section and select the WAN network you wish to configure.
  4. Enable DHCPv6: In the WAN network settings, look for the IPv6 Configuration section. Here, you’ll find an option to enable DHCPv6. Make sure to select it.

Step 2: Set the Delegation Size to 56

Setting the correct delegation size is essential for the proper distribution of IPv6 addresses within your network.

  1. Find the IPv6 Configuration: Still within the WAN settings, locate the IPv6 Configuration section if you’re not already there.
  2. Adjust the Delegation Size: You should see an option for ‘Delegation Size’. Set this to 56. This size is typically recommended for most home and small business networks, allowing for a large number of subnets without overcomplicating your network structure.

Step 3: Configure LAN Network with IPv6 Prefix Delegation

The final step involves setting up your LAN (Local Area Network) to utilize the IPv6 prefix delegation effectively, ensuring devices on your network can obtain IPv6 addresses.

  1. Navigate to LAN Settings: Go back to the ‘Networks’ section in your UniFi Controller settings, but this time, select your LAN network.
  2. Enable IPv6: Look for an option to configure IPv6. Ensure it’s enabled.
  3. Set Prefix Delegation: Within the IPv6 configuration for your LAN, you should see an option for ‘Prefix Delegation’. Enter the IPv6 prefix that was delegated to your WAN. This step is crucial as it tells your network how to distribute IPv6 addresses to connected devices.


By following these steps, you’ve successfully configured your network to support IPv6, leveraging the capabilities of both Cogeco ISP and UniFi networking equipment. This setup not only prepares your network for the future of internet connectivity but also enhances its security and efficiency.

IPv6 is the backbone of the next-generation internet, enabling countless devices to connect seamlessly and securely. As the world continues to move towards this newer protocol, ensuring your network is IPv6-ready is more important than ever. With this guide, you’re well on your way to making the most out of your internet connection, embracing the vast possibilities of IPv6.
