| Address Space | 4.3 billion addresses | 340 undecillion addresses |
Adding both A and AAAA records ensures compatibility with all devices and networks. Follow the steps below to configure them and verify your setup.
How to Add AAAA Record
Understanding AAAA Records
AAAA records play a key role in enabling IPv6 connectivity, similar to how A records support IPv4.
What Do AAAA Records Do?
These records convert human-readable domain names into 128-bit IPv6 addresses. When someone visits a website, their device uses the AAAA record to find the corresponding IPv6 address. For website owners, this helps ensure their site is reachable for users on IPv6 networks.
Here’s an example of how a browser might query an AAAA record:
| Domain | Record Type | IPv6 Address | TTL |
|---|---|---|---|
| example.com | AAAA | 2001:0db8:85a3:0000:0000:8a2e:0370:7334 | 14400 |
This process is an important part of configuring DNS correctly.
How AAAA Records Differ from A Records
While A and AAAA records serve the same basic function, they differ in the type of IP address they handle. Here’s a comparison:
| Feature | A Records | AAAA Records |
|---|---|---|
| Address Protocol | IPv4 | IPv6 |
| Address Length | 32 bits | 128 bits |
| Address Format | Four groups of numbers (e.g., 1.1.1.1) | Eight groups of hexadecimal digits |
| Address Space | Around 4.3 billion addresses | 340 undecillion addresses |
| Example Address | 192.168.1.1 | 2001:0db8:85a3:0000:0000:8a2e:0370:7334 |
| Primary Use Case | Standard internet connectivity | Expanded modern internet infrastructure |
AAAA records address the limitations of IPv4 by supporting IPv6’s massive address pool, which is critical for the internet’s continued expansion [1][2]. To ensure broad compatibility, it’s a good idea to configure both A and AAAA records [1][2].
What You Need Before Adding AAAA Records
Before you start adding AAAA records, make sure you have everything you need to avoid any hiccups during the setup process.
Access to DNS Management Tools
To make changes to your DNS records, you’ll need administrative access to your domain’s DNS management platform. This typically includes:
- Login credentials for your domain registrar’s control panel.
- Permissions to modify DNS records.
- Access to the DNS settings on your hosting platform.
Most domain registrars provide this access through their management dashboard. Once you’re logged in, you’ll be able to make the necessary changes.
Your Server’s IPv6 Address
You’ll need the correct IPv6 address for your server. It should be formatted as eight groups of hexadecimal digits and provided by your hosting provider. Double-check this address to prevent connectivity issues or security problems [2][3].
Control Over Your Domain Name
To modify DNS records, you must have control over your domain. This means:
- Ensuring you have administrative rights to the domain.
- Verifying that your nameservers are set up correctly.
- Confirming your domain registration is active and not expired.
Only authorized users can make DNS changes [1][3]. If you’re using a managed hosting service, you might need to work with your provider to complete these updates.
Once you’ve confirmed all these details, you’ll be ready to configure your AAAA records.
Steps to Add AAAA Records
To set up AAAA records for your domain, ensure you have everything you need, then follow these steps.
Log In to Your DNS Management Panel
Access the DNS management panel provided by your domain registrar or hosting service. Look for the DNS settings associated with your domain.
Locate the AAAA Record Section
Find the area where you can add new DNS records. From the record type dropdown menu, choose ‘AAAA’.
Fill in the AAAA Record Details
Provide the required details for your AAAA record:
| Field | Example |
|---|---|
| Hostname | @ (root domain) or www |
| IPv6 Address | 2001:0db8:85a3:0000:0000:8a2e:0370:7334 |
| TTL | 300 seconds |
Set up AAAA records for both the root domain (use ‘@’ or leave the hostname blank) and the ‘www’ subdomain. Use your server’s IPv6 address and set the TTL to 300 seconds to allow for easier adjustments during the configuration process.
Save and Verify
Review your entries carefully, save the changes, and wait for confirmation. Keep in mind that DNS updates can take some time to propagate across the internet.
After saving, check to ensure the AAAA records are working as expected.

How to Check If Your AAAA Record Works
After setting up your AAAA records, you need to make sure they’re working as intended. Here’s how you can confirm that your IPv6 DNS configuration is set up correctly.
Ways to Verify Your AAAA Records
Command-line tools are a reliable way to check your setup:
Using dig:
dig AAAA example.com
Using nslookup:
nslookup -type=AAAA example.com
If everything is configured correctly, the response will show your IPv6 address.
Prefer a browser-based option? Online lookup tools make it easy:
| Tool Name | Features | Best For |
|---|---|---|
| MXToolbox | DNS checks with instant results | Quick lookups |
| PowerDMARC | Free AAAA record lookup, no account needed | Troubleshooting errors |
| DNS Checker | Tests from multiple global locations | Checking global updates |
Fix Common Issues
If your AAAA records aren’t working as expected, these areas are worth investigating:
-
DNS Update Delays
DNS changes can take up to 48 hours to propagate. Wait at least 15 minutes before testing after making changes, and try testing from different locations or DNS servers. -
Resolution Failures
If your AAAA record isn’t resolving:- Confirm your DNS provider supports IPv6 records.
- Double-check that both A and AAAA records are set up correctly.
- Look for firewall rules that might block IPv6 traffic.
For a quick test of IPv6 connectivity, use this command:
ping -a YOURHOSTNAME -6
Once your AAAA records are verified, keeping them updated and monitored is key to maintaining reliable performance.
Tips for Managing AAAA Records
Managing AAAA records well can make a big difference in your website’s speed and availability. Here’s how to stay on top of it.
Choose the Right TTL Values
The Time-to-Live (TTL) setting determines how long DNS records are cached. Picking the right TTL can balance performance and flexibility.
| TTL Duration | Best Use Case | Impact |
|---|---|---|
| 300s (5 min) | During changes | Faster updates, higher query load |
| 1800s (30 min) | Normal operations | Balanced approach |
| 86400s (24h) | Stable setups | Fewer queries, slower updates |
If you’re planning DNS changes, lower the TTL to 300 seconds at least 24 hours beforehand. After making the changes and ensuring everything works, reset it to a higher value.
Use Both A and AAAA Records
Having both IPv4 (A) and IPv6 (AAAA) records is essential. Here’s why:
- Ensures compatibility with all devices and networks
- Provides fallback options if one protocol doesn’t work
- Delivers better user experience regardless of IP protocol
Example setup:
example.com IN A 192.0.2.1
example.com IN AAAA 2600:1800:5::10
This configuration allows access for both IPv4 and IPv6 users, making your site accessible as IPv6 usage continues to grow.
Review and Update Records Regularly
Keep your DNS records accurate and up-to-date by reviewing them on a schedule:
- Perform basic checks monthly
- Conduct full audits twice a year
- Monitor performance every quarter
Follow these best practices:
- Log DNS changes with timestamps and reasons
- Test DNS resolution from different locations
- Update records immediately when server IPs change
- Maintain backups of DNS settings
"Setting a low TTL before making changes and raising it afterwards can help minimize downtime and ensure smooth transitions" [1]
For businesses, working with professional DNS management services can help ensure everything runs smoothly and your website stays accessible.

FAQs
Should I add an AAAA record?
Whether to add an AAAA record depends on how your server is set up for IP addresses. If your server uses IPv6, you’ll need an AAAA record. For dual-stack setups (supporting both IPv4 and IPv6), it’s best to have both A and AAAA records to ensure compatibility.
| Server Configuration | Record Type Needed |
|---|---|
| IPv6 Only | AAAA Record |
| IPv4 Only | A Record |
| Dual-Stack | Both A and AAAA |
Here are some important points to consider:
- Server Configuration: Check with your hosting provider to confirm your server’s IP setup. Many hosting services now support dual-stack configurations [2].
- DNS Management: Make sure your DNS provider supports IPv6 and that your DNS settings match your server’s capabilities [1].
- Implementation Plan: If your server supports dual-stack, configure both A and AAAA records. This ensures your website is accessible across both IPv4 and IPv6 networks.
It’s a good idea to regularly review your DNS settings. Use lower TTLs (30-300 seconds) if you expect frequent changes, or higher TTLs for more stable configurations [1]. For businesses managing multiple domains or complex setups, professional DNS management services can help streamline record configuration and reduce the risk of errors or downtime.
