How does it work?
With a DNS lookup you query a record from a domain's DNS servers. Handy when checking changes, migrations and mail settings.
Frequently asked questions
Which record type do I need?
A and AAAA for websites, MX for mail, TXT for SPF, DMARC and verifications, NS for the nameservers.
Why do I not see my change yet?
DNS is cached. Wait until the TTL of the old record has expired.
Is this a live query?
Yes, but through a resolver that caches briefly, so a very recent change may be missing.
Need help with your email security?
We set up DMARC, SPF, DKIM and MTA-STS for you and keep an eye on it, as part of Security and Monitoring.
