IPv6 is the most recent version of the Internet Protocol, which identifies devices across the internet. IPv6 was introduced in 2013, and while Apple included some preliminary settings for the router, not much has changed since then. IPv6 is designed to replace IPv4, which is still in use today. IPv4 has a limited number of addresses, which are running out, whereas IPv6 has a much larger address space. IPv6 also offers other benefits such as improved security and faster connection speeds. IPv6 is available on Airport Extreme, and users have reported using IPv6 with Airport Extreme for several years without any issues. However, some users have reported issues with IPv6 DNS and connection sharing. To set up IPv6 on Airport Extreme, users should select 'Automatic' in the Configure IPv6 menu and choose Native in the IPv6 Mode menu.

What You'll Learn
IPv6 connection sharing
To enable IPv6 connection sharing, you can find the checkbox after clicking the "Internet options" button at the bottom of the "Internet" pane of the Airport utility. Checking this box turns on end-to-end IPv6 connectivity for devices on your LAN if your ISP is set up with IPv6. It tells your router to give devices an address from its delegated set.
If you are using an Apple router, you can set it up in bridge mode behind another router, which will then handle DHCP. Alternatively, you can use another router in front of the Airport Extreme, which can be used in bridge mode.
To configure IPv6 on your Airport Extreme, select "Automatic" in the "Configure IPv6" menu, and choose "Native" in the "IPv6 Mode" menu.

IPv6 compatibility
While IPv4 is still the most used and familiar IP version, IPv6 adoption has been gradually increasing. As of 2016, over 25% of all Internet-connected networks supported IPv6 connectivity, with 49 countries delivering more than 5% of their traffic over the IPv6 network.
To check if a domain is IPv6 compatible, you can use online IPv6 Compatibility Checker tools. These tools verify if a domain is using IPv6 on their network by querying the domain's DNS records and checking if the IPv6 DNS records resolve correctly.
In terms of specific settings for Airport Extreme, a router, there are a few considerations for IPv6 compatibility. Firstly, in the Configure IPv6 menu, selecting "Automatic" and choosing Native in the IPv6 Mode menu should enable IPv6 functionality. Additionally, enabling the "IPv6 Connection Sharing" option is crucial for turning on end-to-end IPv6 connectivity for devices on your LAN if your ISP supports IPv6. However, it's important to note that Airport Extreme has very basic IPv6 functionality, and you may need to use another router if you require advanced features or the passing on of IPv6 DNS server information from your provider.

IPv6 configuration
IPv6 Connection Sharing:
The "Enable IPv6 Connection Sharing" option is a crucial setting for establishing IPv6 connectivity. Enabling this option allows your Airport Extreme to provide IPv6 addresses to devices on your Local Area Network (LAN). This setting is typically found in the "Internet Options" section of the Airport Utility on your Mac or iOS device.
IPv6 Mode:
In the IPv6 settings, it is recommended to set the IPv6 mode to "Native". This setting ensures that your Airport Extreme operates using IPv6 natively, rather than through a ""Tunnel" mode, which may be less efficient.
Configure IPv6:
In the "Configure IPv6" menu, selecting "Automatic" allows your Airport Extreme to autodetect the necessary settings. This simplifies the configuration process, as your device will automatically adjust its settings based on your network environment.
IPv6 DNS:
One common issue with Airport Extreme is its limited handling of IPv6 DNS (Domain Name System) information. The local DHCP (Dynamic Host Configuration Protocol) server within the Airport Extreme may not correctly process IPv6 DNS server information. This can result in devices connected to your network being unable to access certain websites or services. A workaround for this issue is to use another router in front of the Airport Extreme, allowing the compliant router to handle DHCP and IPv6 DNS information.
ISP Compatibility:
Ensure that your ISP supports IPv6 and provides the necessary IPv6 configuration information. Some ISPs may enforce or highly encourage the use of IPv6, while others may be slower to adopt it. Check with your ISP to confirm their IPv6 support and any specific settings they recommend.
In summary, configuring IPv6 on your Airport Extreme involves enabling IPv6 Connection Sharing, setting the IPv6 mode to Native, and allowing the device to autodetect settings by selecting Automatic in the Configure IPv6 menu. Be mindful of potential issues with IPv6 DNS handling, and ensure your ISP provides IPv6 support. With these steps, you should be able to successfully set up and use IPv6 on your Airport Extreme.

IPv6 DNS
When it comes to configuring IPv6 DNS on your Airport Extreme router, there are several steps to follow:
- Access Router Settings: Begin by accessing your Airport Extreme router's settings. This can typically be done through a web interface or a dedicated router configuration application provided by the manufacturer.
- Locate IPv6 Settings: Within the router settings, look for the "IPv6" or "IPv6 Configuration" section. This is where you will make the necessary adjustments to enable and configure IPv6 DNS.
- Enable IPv6: Ensure that IPv6 is enabled on your router. Look for an option like Enable IPv6 or IPv6 Connection. If it is not already enabled, turn it on.
- Select IPv6 Mode: Choose the appropriate IPv6 mode for your network. The most common modes are "Native" and "Tunnel." Native mode is typically used when your ISP directly provides IPv6 connectivity, while Tunnel mode is used with tunneling protocols to encapsulate IPv6 packets within IPv4.
- Configure DNS Settings: In the IPv6 settings, look for the "DNS" or "DNS Settings" section. Here, you can specify the IPv6 DNS server addresses you want to use. You can obtain these addresses from your ISP or opt for public DNS services like Google Public DNS, which offers IPv6 DNS servers at 2001:4860:4860::8888 and/or 2001:4860:4860::8844.
- Save and Apply Changes: Once you have entered the desired IPv6 DNS server addresses, save and apply the changes. Your router may prompt you to restart or apply the new settings.
- Test IPv6 Connectivity: After configuring IPv6 DNS, test your IPv6 connectivity to ensure it is working correctly. You can use online tools like test-ipv6.com or Google's IPv6 test to verify that your IPv6 setup is functioning as expected.
Considerations and Limitations
It is important to note that while IPv6 DNS is a significant advancement, there are still some considerations and limitations:
- Consumer Device Support: Some consumer devices may not yet fully support IPv6 DNS. In such cases, DNS may fall back to functioning over IPv4, as DNS servers often still provide AAAA records over IPv4.
- ISP Compatibility: Ensure your ISP offers IPv6 support. While IPv6 adoption has been growing, not all ISPs have fully embraced it, and some may not provide IPv6 connectivity or DNS services.
- IPv4 Compatibility: IPv6 DNS servers cannot be reached by IPv4-only peers or hosts. This limitation underscores the ongoing transition from IPv4 to IPv6, and it is important to ensure compatibility with existing IPv4 infrastructure during this period.
- Security Considerations: IPv6 DNS may have security implications, especially when combined with certain protocols like IPsec. Careful configuration and updates are necessary to maintain a secure network environment.
