DNS Lookup: Check Domain DNS Records

See a domain's A, AAAA, MX, TXT, NS and CNAME records: everything you need when setting up email, pointing a domain to a VPS or troubleshooting.

Domain name

Checking a domain's DNS records

The tool queries the Domain Name System and shows the domain's current resource records: A, AAAA, MX, TXT, NS and CNAME. In one step you can see which server the site points to, where email is delivered, which name servers host the zone and which verification strings sit in TXT. It is handy when launching a new site, moving to a different host, or troubleshooting a domain that points "somewhere else".

What each record type does

Type	Purpose
`A`	IPv4 address of the server the domain points to
`AAAA`	IPv6 address of the server
`MX`	Mail servers that accept email for the domain
`TXT`	SPF, DKIM, DMARC and ownership verification records
`NS`	Name servers that host the zone
`CNAME`	An alias that points to another hostname

Why changes do not show up right away

After you edit records at your registrar or DNS host, the new values do not spread across the internet instantly. Every record has a TTL (time to live): how long resolvers may cache the answer. Until the old answer expires, some users still see the previous values, and full propagation can take anywhere from a few minutes to a day. If the TTL was high, expect to wait longer; lowering it a day before a planned migration speeds up the switch.

Two common tasks benefit most from this check. For email deliverability, look at MX and TXT: correct MX records plus valid SPF, DKIM and DMARC reduce the chance of landing in spam, and major mailbox providers now require them for bulk senders. When pointing a domain to a server, check A and AAAA: they must match your host's current IP, and NS confirms the zone is delegated to the DNS provider where you are making changes.

Frequently asked questions

Which DNS record types does the tool show?

A, AAAA, MX, TXT, NS and CNAME, the core set for troubleshooting a website and email.

Why do DNS changes not appear immediately?

Records are cached according to their TTL, so some resolvers keep returning old values until the cache expires. Full propagation can take up to a day.

Which record handles a domain's email?

MX records control where incoming mail is delivered, while TXT records with SPF, DKIM and DMARC help prove outgoing mail is legitimate.

What is the difference between A and AAAA?

An A record holds the server's IPv4 address, while AAAA holds an IPv6 address for the same or a different host.

What is a CNAME record for?

A CNAME creates an alias that points to another hostname, which is convenient for subdomains and third-party services such as CDNs.

How do I check which server a domain points to?

Look at the A and AAAA records: the IP address listed there is the server that answers for the domain.
