DNS Lookup
DNS is the address book of the internet, and most domain problems start here. This tool resolves a name's live records — the A and AAAA entries that point it at servers, the MX records that route its mail, and the TXT records that prove ownership and authorize senders — so the full configuration is visible at a glance.
What you get
- A and AAAA records: the IPv4 and IPv6 addresses the domain resolves to right now.
- MX records with their priorities, showing which mail servers accept the domain's email.
- TXT records, including SPF and the verification strings used by Google, Microsoft, and others.
- NS and CNAME delegation, so you can trace how the name is wired together.
Frequently asked questions
- Which record types does this check?
- The common set that actually matters in practice — A, AAAA, MX, TXT, NS, and CNAME. That covers addressing, mail routing, ownership proofs, and delegation.
- I changed my DNS but the result looks old — why?
- DNS records are cached across resolvers according to each record's TTL. A change can take anywhere from a few minutes to a day or two to propagate everywhere.
- Can this tell me if my email is set up correctly?
- It surfaces the raw MX and TXT/SPF records. For a full SPF, DKIM, and DMARC verdict, use the dedicated email-authentication checker instead.
- Does a lookup cost credits?
- This page is free to read. A DNS lookup costs 1 credit, and cached re-checks of the same domain are free.
