DNS Record Check: finding a domain, and understanding it
Domain research involves availability, WHOIS, pricing and DNS. DNS Record Check puts those in one search, plus AI name ideas when your first choice is taken.
Naming something is hard, and finding the domain is often harder. You think of a name, check it, find it taken, try three variations, check a different extension, then wonder whether the registrar's renewal price is going to sting next year. DNS Record Check is the tool I run to make that process less tedious.
What DNS Record Check does
- Availability across more than a thousand TLDs in one search, not just .com.
- Premium and aftermarket listings when a name is for sale.
- AI-generated name ideas when the one you wanted is gone.
- WHOIS lookups to see registration details for a domain.
- Bulk and multi-TLD search for checking a shortlist at once.
- Registrar price comparisons covering registration, renewal and transfer costs by TLD.
- DNS and security tools for looking at how a domain is set up.
A few domain lessons worth knowing
Look at renewal prices, not just first-year prices. Some extensions are cheap to register and expensive to keep.
The competition for names is real. The Domain Name Industry Brief counted 401.6 million domain name registrations across all top-level domains in the second quarter of 2026, 179.1 million of them in .com and .net combined. Your first choice is usually taken, which is why the alternatives matter.
Short and sayable beats clever. If you have to spell it out loud every time, it will cost you.
Know your DNS before you change anything. Before moving a domain or pointing it at a new host, write down every existing record, especially MX, SPF, DKIM and DMARC. It's easy to break email while fixing a website, and you often won't notice until messages quietly stop arriving.
That last one comes from experience moving my own sites around: the website part of a DNS change is easy, and the mail records are the part that needs care.

Frequently asked questions
What does DNS Record Check do?
It checks whether a domain is available, shows WHOIS and DNS records, compares pricing, and suggests AI-generated name ideas when your first choice is taken.
Why does a domain's renewal price matter?
Some extensions and registrars price the first year low and renew much higher. Check the renewal price before you commit to a name you'll keep for years.
What are the main DNS records to know?
A and AAAA records point a name at a server, CNAME records alias one name to another, MX records route email, and TXT records hold verification and email-security settings.
Can I look up a domain I don't own?
Yes. DNS records and most registration data are public, which is what makes a lookup tool useful for research.
