What Is a DNS Lookup?
DNS is like the address book of the internet. When something goes wrong, like a site not loading after a move or emails landing in spam, the answer is usually in the DNS records. This tool reads them through Google Public DNS, checks your SPF and DMARC email records, and gives you a simple summary of who provides each service.
- A, AAAA, CNAME, MX, NS, TXT, SOA and CAA records
- SPF and DMARC email checks
- Names your hosting, DNS and email providers
- Uses Google Public DNS
- Free, no sign-up
How to Use the DNS Lookup
Enter a domain
Run the lookup
Read the summary
Check each record

DNS changes take time
- After you change a record, it can take from a few minutes to 48 hours to update everywhere, depending on the TTL.
- Lower the TTL a day before a planned move.
- Only one SPF record is allowed. Merge them if you have two.
- Start DMARC with p=none, then move to quarantine or reject.
DNS Record Types Explained
| Record | What it does |
|---|---|
| A | Points the domain to an IPv4 address (the web server) |
| AAAA | Points the domain to an IPv6 address |
| CNAME | Makes a name an alias of another name |
| MX | Says which servers receive email for the domain |
| NS | Says which name servers run the DNS |
| TXT | Text records for SPF, DMARC and site verification |
| SOA | Main settings of the DNS zone |
| CAA | Which certificate authorities may issue SSL certificates |
How the DNS Lookup Works
- 01
You enter a domain
The domain is cleaned of https://, paths and spaces.
In your browser - 02
Google Public DNS is asked
Each record type is requested over DNS-over-HTTPS from Google Public DNS.
Our server - 03
Email records are checked
SPF is read from TXT and DMARC from _dmarc, then checked for common mistakes.
In your browser - 04
Providers are named
IP ranges, name servers and MX hosts are matched to known providers like Cloudflare or Google Workspace.
In your browser - 05
Results are shown
Every record is listed with its value, TTL and meaning.
In your browser
Email Checks We Run
- SPF: only one record allowed. It should end in
~allor-all. - DMARC: a TXT record at
_dmarc.yourdomain.com.p=noneonly reports,p=quarantineorp=rejectprotect. - No MX: the domain cannot receive email.
Is the DNS Lookup Accurate?
- Every record type matches a direct DNS query
- SPF and DMARC problems are found
- Known providers are named correctly
- Domains with no records show a clear message
- TTL values are shown
Accuracy in plain words
DNS answers can be cached. If you just changed a record, Google Public DNS may still show the old value until the TTL runs out. Provider names are a helpful guess, not a guarantee.

DNS Lookup FAQ
What is a DNS lookup?
It is a check that shows the DNS records of a domain, like where the website and email are hosted.
Is this DNS lookup tool free?
Yes. It is 100% free, with no sign-up.
How long do DNS changes take?
Usually minutes to a few hours, but up to 48 hours in some cases. It depends on the TTL of the old record.
What is an MX record?
An MX record says which mail servers receive email for your domain.
What is SPF and DMARC?
SPF lists the servers allowed to send email for your domain. DMARC tells receivers what to do with email that fails these checks.
Why do I see old records after a change?
DNS answers are cached until their TTL runs out. Wait, then check again.
Does DNS affect SEO?
Indirectly. Wrong DNS can take a site offline or slow it down, which hurts users and crawling.
