Domain Analyzer

Enter any domain name and this free domain analyzer shows its technical foundations: the live DNS records (A and AAAA for hosting, MX for email, NS for nameservers, TXT for verification and mail security, plus CNAME and SOA), and — from the official registry data — the registrar, the registration date (the domain's true age) and the expiry date. Use it to verify a domain before buying it, to debug why email is not arriving, to confirm a client's DNS changes actually propagated, or to check when a domain you want might expire. Everything shown is public record, fetched live from public DNS-over-HTTPS resolvers and the registry's RDAP service.

How to use this tool

  1. Type a bare domain like example.com.
  2. Click Analyze domain.
  3. Read the registration panel: registrar, age, expiry.
  4. Scan the DNS tables record type by record type.

Worked example

Before buying, a 'premium' domain turns out to be 3 months old with parking-service TXT records — a very different asset from the aged domain it was pitched as.

Frequently asked questions

What do the DNS record types mean?

A / AAAA point the domain to its web server (IPv4 / IPv6). MX records route email to the mail provider — no MX, no email. NS records name the DNS host that manages the domain. TXT records carry verifications (proving ownership to Google and others) and email security policies (SPF, DKIM pointers, DMARC). CNAME makes one name an alias of another, common for www and subdomains. SOA is the zone's administrative record. Together they are the domain's wiring diagram.

Why does the registration section say "not available" for some domains?

Registration details come from RDAP, the registry's official lookup protocol. Most major extensions (.com, .org, .net and hundreds more) publish through it, but some country extensions still run older systems or restrict publication, and privacy-protected registrations hide personal fields by design. When RDAP has nothing, the analyzer says so plainly rather than guessing — the DNS half of the report works for every domain regardless.

How do I use this before buying a domain?

Check three things: the registration date (an aged domain registered years ago behaves differently from one created last week — a classic spam signal when paired with a "established business" claim); the registrar and expiry (a domain expiring within weeks that the seller has not renewed is leverage or a red flag); and the TXT/MX history hints (records pointing at bulk-mail or parking services suggest prior use you should investigate further with archive tools before paying a premium).

My DNS change is not showing — is the analyzer stale?

It queries Google's public resolver live, the same source most of the internet effectively uses, so what it shows is what the world sees now. DNS changes propagate according to the old records' TTL (time-to-live): if the old TTL was 24 hours, some resolvers may legitimately serve the old answer for up to a day. The TTL values shown beside each record tell you the maximum wait for that record type.
