How to run a useful DNS check
- 1Enter only the root domain, for example
example.com—not an email address or URL. - 2Run the check after saving records at the authoritative DNS provider.
- 3Compare every public answer with the Name, Value and Priority shown in mailbox setup.
- 4Correct missing or conflicting records, allow caches to refresh, then check again.
Records and fields checked
| Record | Name / Host | What the value means | Priority |
|---|---|---|---|
| MX | @ | Where incoming email is delivered | Required for MX |
| TXT (SPF) | @ | Which services may send for the domain | — |
| TXT (DMARC) | _dmarc | Authentication policy and reporting | — |
| NS | @ | Which provider is authoritative for DNS | — |
Common DNS Checker problems
- Entering
https://example.cominstead ofexample.com. - Editing records at the registrar while another provider's nameservers are authoritative.
- Checking immediately while the previous TTL is still cached.
- Publishing two SPF records or appending the domain twice to a hostname.

자주 묻는 질문
Does DNS Checker change my records?
No. It only reads public DNS answers.
Why does the old value still appear?
Resolver caches can retain the previous value until its TTL expires.
Why is a record missing after I saved it?
Confirm you edited the authoritative DNS provider and did not duplicate the domain in the Host field.
