AAAA Record Lookup

Use the AAAA Record Lookup tool to check which IPv6 address is connected to a domain or subdomain. If your website, server, CDN, or cloud infrastructure supports IPv6, this tool helps you confirm whether your DNS AAAA record is configured correctly.

An AAAA record is the DNS record used to map a hostname to an IPv6 address. With IPMYP, you can enter a domain such as example.com or a subdomain such as www.example.com and quickly see the IPv6 address and related DNS details returned for that hostname.

If you want to see whether your current connection is using IPv4 or IPv6, you can check your public IP address before testing the DNS records of a domain.

What Is an AAAA Record?

An AAAA record, also called a Quad A record, is a DNS record that maps a domain name or subdomain to an IPv6 address. It works similarly to an A record, but instead of returning an IPv4 address, it returns an IPv6 address.

For example, if example.com has an AAAA record pointing to 2001:db8::1, IPv6-enabled clients can use that address to connect to the server.

AAAA records are commonly used for:

• Connecting a domain to an IPv6-enabled web server.
• Adding IPv6 support for websites, APIs, apps, and services.
• Pointing subdomains such as ipv6.example.com, api.example.com, or app.example.com to IPv6 infrastructure.
• Testing IPv6 readiness after server, DNS, CDN, or cloud configuration changes.

If an AAAA record is missing, wrong, or outdated, users connecting over IPv6 may fail to reach the correct server or may experience connection problems.

AAAA Record vs A Record

The difference between an A record and an AAAA record is the IP version they use.

• A Record: Maps a domain to an IPv4 address, such as 203.0.113.10.
• AAAA Record: Maps a domain to an IPv6 address, such as 2001:db8::1.

If your domain supports both IPv4 and IPv6, it may have both A and AAAA records. IPv4 clients use the A record, while IPv6-capable clients may use the AAAA record.

If you also need to check the IPv4 address of a domain, use the A Record Lookup tool.

How to Use the AAAA Record Lookup Tool

Using the IPMYP AAAA Record Lookup tool is simple and does not require terminal commands or DNS software.

1. Enter a domain name or subdomain, such as example.com or www.example.com.
2. Run the AAAA record check.
3. IPMYP sends a DNS query for the hostname you entered.
4. Review the result, including IPv6 address, record type, hostname, and TTL when available.
5. Use the result to confirm whether the domain points to the correct IPv6 address.

For a broader check that includes DNS records, WHOIS, Reverse DNS, Ping, Traceroute, SSL, and other diagnostics, use the main DNS lookup tool and online network tools hub.

What Information Does an AAAA Record Report Show?

After running the check, the AAAA record report may show several important DNS details.

• Host: The domain or subdomain being checked.
• Type: The DNS record type, which should be AAAA.
• IPv6 Address: The IPv6 address connected to the domain, such as 2001:db8::1.
• TTL: The Time To Live value that tells DNS resolvers how long they may cache the record.

If a domain has multiple AAAA records, the tool may show more than one IPv6 address. This can happen with load balancing, cloud infrastructure, CDN routing, or multi-server IPv6 deployments.

When Should You Check a DNS AAAA Record?

AAAA record lookup is useful whenever you need to verify IPv6 DNS configuration for a domain or subdomain. It is especially helpful after enabling IPv6, changing hosting, updating DNS records, or troubleshooting access issues for IPv6 users.

After Enabling IPv6 on a Server

When you enable IPv6 on a VPS, dedicated server, cloud server, or hosting account, the domain must have a correct AAAA record to point to the IPv6 address. Checking the record confirms whether the DNS side is configured properly.

When IPv6 Users Cannot Access a Website

Some users and networks prefer IPv6 when it is available. If the AAAA record points to the wrong IPv6 address, IPv6 users may see connection errors even if the website works correctly over IPv4.

When Testing Cloud or CDN Configuration

If you use a CDN, reverse proxy, load balancer, or cloud security provider, your public AAAA record may point to that provider’s IPv6 address instead of your origin server. This can be expected, but it is still important to verify that the visible DNS record matches your provider’s instructions.

When Auditing DNS Settings

AAAA record lookup helps developers, system administrators, and webmasters review whether a domain is ready for IPv6 traffic and whether DNS results match the intended infrastructure.

Why Does the AAAA Record Show a Different IPv6 Address?

The IPv6 address returned by DNS may be different from the address configured directly on your origin server if you use a CDN, DDoS protection service, reverse proxy, cloud load balancer, or managed hosting platform.

In these cases, the public DNS record may point to the provider’s edge infrastructure rather than your real backend server. This is normal for many modern hosting and security setups.

How Long Do AAAA Record Changes Take?

AAAA record changes may appear quickly, but visibility across the internet depends on DNS caching and TTL values. Some DNS resolvers may update within minutes, while others may keep older records for a longer period.

If you recently changed an AAAA record, you may temporarily see different results depending on the resolver, network, or region being used. This is usually related to DNS cache and propagation behavior.

Common Use Cases for AAAA Record Lookup

• IPv6 setup verification: Confirm that a domain points to the correct IPv6 address.
• Website migration: Check whether IPv6 DNS records were updated after moving to a new server.
• CDN and cloud testing: Verify whether the domain points to the expected IPv6 endpoint.
• Subdomain testing: Check IPv6 records for API, app, panel, staging, or service subdomains.
• Connectivity troubleshooting: Identify whether IPv6 DNS misconfiguration may be causing access problems.
• DNS audits: Review whether important domains and subdomains are properly configured for IPv6.

Best Practices for Managing AAAA Records

• Only create an AAAA record when the destination server or service is actually configured for IPv6.
• Verify the correct IPv6 address before adding or updating the record.
• Check both the root domain and important subdomains after DNS changes.
• Lower TTL before planned migrations when possible, then raise it again after the change is stable.
• Make sure your web server, firewall, CDN, and SSL configuration support IPv6 if you publish an AAAA record.
• Remove outdated AAAA records if the IPv6 destination is no longer active.

Frequently Asked Questions

What does an AAAA Record Lookup do?

An AAAA Record Lookup checks the DNS AAAA record of a domain or subdomain and shows the IPv6 address connected to it. This helps you confirm whether a domain is configured correctly for IPv6 access.

What is a DNS AAAA record?

A DNS AAAA record maps a domain name to an IPv6 address. It is used when a website, server, or service supports IPv6 connectivity.

What is the difference between A and AAAA records?

An A record points a domain to an IPv4 address, while an AAAA record points a domain to an IPv6 address. Both are DNS address records, but they use different IP versions.

Do I need an AAAA record for my website?

You need an AAAA record only if your website or server supports IPv6. If your site only uses IPv4, an A record may be enough.

Can a domain have multiple AAAA records?

Yes. A domain can have multiple AAAA records. This may be used for load balancing, redundancy, CDN routing, cloud hosting, or multi-server IPv6 infrastructure.

Why is my AAAA record not updating?

Your AAAA record may not appear updated everywhere because of DNS caching, TTL values, resolver behavior, or propagation delay. Wait for the TTL period and check again from different networks if needed.

Why does my AAAA record show a CDN IPv6 address?

If you use a CDN, proxy, or cloud security service, your public AAAA record may show the provider’s IPv6 address instead of your origin server IPv6 address. This is common in CDN and reverse proxy setups.

Can an incorrect AAAA record break my website?

Yes. If your AAAA record points to a wrong or unreachable IPv6 address, IPv6 users may fail to connect even if IPv4 users can still access the website.
