About this tool. NS records name the servers that hold your domain's DNS zone — every other record depends on them. This lookup lists your nameservers, resolves them, and identifies the DNS host behind them.
Ten signals decide whether your mail arrives. You just checked one.
Nameservers that disagree serve different answers to different people, which is why a record you published can look correct to you and missing to a mail server.
- SPF, DKIM, DMARC, MX and blocklist status, graded A to F in one pass
- Every problem written out in plain English, with the record to publish
- Saved under Reports, so you can re-run it and see what changed
- One domain watched against the blocklists daily

How to read your NS results
- NS records list the nameservers that are authoritative for the domain, meaning they hold the real answers.
- These should match what your registrar shows. A mismatch means DNS changes may not take effect.
Common problems and how to fix them
DNS changes are not taking effect
Confirm these nameservers match the ones set at your registrar. If they point at an old provider, updates you make elsewhere are ignored.
Common questions.What is an NS record?
It names the servers responsible for answering DNS queries for a domain.
Where do I change my nameservers?
At your domain registrar, not in the DNS zone itself. The zone lives on whichever nameservers the registrar points to.
