Which DNS record maps an IPv6 address to a domain name?

N10-008 By islever Editorial Last updated

Short answer

A AAAA

Question

Which of the following should be used to associate an IPv6 address with a domain name?
  1. AAAA Correct Answer
  2. A
  3. SOA
  4. TXT

Key Takeaways

This question tests your understanding of DNS record types and specifically which one is used for IPv6 addresses; the key trap is confusing A (IPv4) with AAAA (IPv6).

The AAAA record is the DNS resource record that associates an IPv6 address with a domain name, analogous to the A record for IPv4. Community consensus confirms A as the correct answer for the N10-008 exam.

Common mistake: Choosing A record (option B) is a common mistake because A records are the most familiar DNS address records, but they only map hostnames to IPv4 addresses, not IPv6.

Expert Analysis

Why the Answer Is Correct

The AAAA record (also called a 'quad-A' record) is the DNS record type explicitly designed to map a fully qualified domain name to a 128-bit IPv6 address. It works similarly to an A record but for IPv6, enabling clients to resolve domain names to IPv6 destinations. Community comments, including from users who answered A and provided explanations, consistently confirm this, with one commenter noting 'the AAAA record is used in DNS to associate an IPv6 address with a domain name.'

Why the Other Options Are Wrong

Option B, A record, maps a domain name to an IPv4 address, not IPv6, making it incorrect for this scenario. Option C, SOA (Start of Authority), stores zone administrative information such as the primary name server and email contact, not host addresses. Option D, TXT record, holds arbitrary text data often used for verification or SPF, and does not map names to IP addresses. The only option matching the IPv6 requirement is AAAA.

Community Comment Notes

A voter who chose AAAA gave the clearest correct explanation. Another commenter sarcastically claimed the voter 'is definitely not gonna make it as a network engineer,' which appears to be a joke or confusion, but the overwhelming majority (90% votes for A) supports AAAA as the correct answer. No comment suggests any alternative answer, reinforcing the correct choice. A comment mentioning 'GPTTTTTT' with answer D seems to be a spam or AI-generated distraction and is not technically valid.

Exam Strategy

Memorize the purpose of common DNS record types, especially A (IPv4), AAAA (IPv6), CNAME, MX, TXT, and SOA. On the exam, when you see 'IPv6 address' and 'domain name,' immediately think AAAA; if the question says 'IPv4 address,' choose A instead.

    The AAAA record is used in DNS to associate an IPv6 address with a domain name. This record type maps a domain name to an IPv6 address, similar to how an A record maps a domain name to an IPv4 address. B. A: The A record maps a domain name to an IPv4 address, not an IPv6 address. C. SOA: The Start of Authority (SOA) record provides information about the DNS zone, including the primary name server and contact email, but it does not map domain names to IP addresses. D. TXT: The TXT record is used to hold arbitrary text data for various purposes, such as verification or configuration information, but it does not associate domain names with IP addresses.

    AAAA record is used to map a domain name to an IPv6 address. They are similar to A records, which map domain names to IPv4 addresses, but are used specifically for IPv6.
