What type of DNS record is used to map hostnames to IPv6 addresses?

Quick Scoop

  • The DNS record that maps a hostname to an IPv6 address is an AAAA record.
  • It’s the IPv6 equivalent of an A record , which maps hostnames to IPv4 addresses.

Short Answer

The DNS record used to map hostnames (or domain names) to IPv6 addresses is an AAAA DNS record.

Mini Breakdown

  • A record : Maps a domain to an IPv4 address (32‑bit, e.g. 203.0.113.10).
  • AAAA record : Maps a domain to an IPv6 address (128‑bit, e.g. 2001:db8::1).
  • MX record : Used for mail exchange (email servers), not for direct IP mapping.
  • CNAME record : Creates an alias from one name to another, not directly to an IP.

So if an exam, quiz, or forum question asks:

“What type of DNS record is used to map hostnames to IPv6 addresses?”

the correct choice is:

AAAA record (quad‑A).

Tiny Example

Imagine you own example.com and your server has an IPv6 address 2001:db8:85a3::7334. You would add a DNS record like:

  • Type: AAAA
  • Name/Host: example.com
  • Value: 2001:db8:85a3::7334

When an IPv6‑capable client looks up example.com, DNS returns that IPv6 address using the AAAA record.

TL;DR: The DNS record type that maps hostnames to IPv6 addresses is the AAAA record.
