Clean the input
Paste a domain or full URL. We extract the hostname, lower-case it and convert international names to ASCII (Punycode).

How a domain lookup works
Three steps, usually completed in under two seconds.
Find the registry
The IANA directory tells us which registry runs the extension, including multi-part ones like .co.uk.
Read and display
We fetch RDAP and WHOIS records, merge them and show registrar, dates, nameservers, DNS records, status and contacts.
DNS records explained
Every domain resolves through DNS. Here is what each record type means and why it matters.
A Record
Maps a domain to an IPv4 address. The most common record — it tells browsers where your website lives.
AAAA Record
Maps a domain to an IPv6 address. The modern successor to A records, used for next-generation internet.
MX Record
Mail Exchange — tells the internet which servers handle email for your domain.
NS Record
Name Server — points to the authoritative DNS servers that hold your domain's records.
TXT Record
Holds text data for verification, SPF, DKIM and domain ownership checks.
CNAME Record
Canonical Name — aliases one domain to another, often used for subdomains.
What people use DomainLookup for
Real-world use cases for domain and DNS research.
Before buying a domain owner
Check registration age, expiry date and registrar. A name expiring next week is a very different conversation than one renewed for ten years.
Investigate a suspicious link
Phishing sites are often days old. A domain created yesterday that imitates a bank is a strong warning sign.
Fix DNS and migration issues
Confirm the nameservers a domain really uses and whether a registrar lock or hold is blocking a change.

Frequently asked questions
Is the domain data live?
Yes. Each search queries the registry's RDAP service and, where available, the WHOIS server. Results are cached for about 60 seconds to keep things fast and fair to the registries.
Why is the domain owner's name missing?
Since 2018 most registries and registrars hide personal contact details for privacy (GDPR and similar laws). DomainLookup shows only what is published and never guesses an owner.
Does "no record found" mean the domain is available?
Usually yes. When the registry confirms there is no record, we show the domain as available. Reserved and blocked names can look the same, so always confirm with a registrar before buying.
What is the difference between WHOIS and RDAP?
WHOIS is the older plain-text protocol. RDAP (Registration Data Access Protocol) is the modern, structured replacement that returns JSON. DomainLookup queries both and shows whichever is available.
