netlupaLook up a domain's AAAA record
The AAAA record gives a domain's IPv6 address. Without one, the site is only reachable over IPv4.
What is an AAAA record?
It is the IPv6 equivalent of the A record: it maps a name to a 128-bit address. It is called “quad A” because an IPv6 address is four times as long as an IPv4 one. Modern browsers ask for the A and AAAA records at the same time and use IPv6 when it is available and works well.
Lookups by record type
Frequently asked questions
Is an AAAA record required?
No, but it is recommended: more and more mobile users browse over IPv6, and without it their connection relies on the carrier's translation mechanisms.
How long does a DNS change take to propagate?
As long as the old record's TTL: from a few minutes to 24 or 48 hours. Nameserver (NS) changes usually take longer, because the TTL of the delegation in the TLD is high.
What does NXDOMAIN mean?
That the name you looked up does not exist in DNS: the domain is not registered, has expired or was mistyped.
Which DNS servers does this tool ask?
No middleman: Netlupa runs its own resolver, which starts from the root servers and asks each domain's official DNS servers directly.
Can I do a reverse DNS lookup of an IP?
Yes: look the IP up with the API (/api/dns/ptr/8.8.8.8) or use the WHOIS tool to find out who it belongs to.
Why do I see a different value than in my DNS panel?
Because resolvers still have the previous value cached. Wait for the time shown in the TTL, or check that you edited the zone at the provider listed in the NS records: if the domain uses other DNS servers, changes in your panel have no effect.
What is a record's TTL?
The time, in seconds, other servers may keep the answer before asking again. 3600 is one hour. A low TTL makes changes show up sooner, at the cost of more queries.
