Frequently Asked Questions
Can I use the tools for free?
Yes. Every visitor gets 50 free lookups per day with no account required, and signing up unlocks the same 50 daily lookups tied to your account. Free usage covers core tools like DNS Inspector, WHOIS Lookup, and IP Intelligence with full results, no ads, and no feature restrictions. Paid plans unlock additional tools like Reverse WHOIS and Expiring Domains, plus higher volume, bulk operations, and API access.
Why charge for tools that are free elsewhere?
DNS Checker is built and maintained by a single developer, not a company with ad revenue or venture funding. Running multiple tools across dedicated servers, processing 183 million domain records daily, and keeping everything fast and reliable comes with significant infrastructure costs. Subscriptions make it possible to keep the site completely ad-free, invest in better tools and data quality, and offer a premium experience without cutting corners. Every subscription directly supports the project and helps keep it running.
Is there a refund policy?
Your first subscription comes with a 7-day, no-questions-asked money-back guarantee. Use your plan’s full credit allowance, try every tool, and see how it fits your workflow completely risk-free. If it is not the right fit, a full refund is just a message away. The guarantee applies once per account to the initial subscription purchase and does not cover renewals, plan changes, or top-up credit packs. Full details in the Terms of Service. Fair warning though: once you see results presented with the level of detail, visual clarity, and actionable insights that DNS Checker delivers, the typical bare-bones lookup tools out there start to feel like a downgrade.
Can I cancel anytime?
Yes, cancel from your dashboard at any time with no penalties or cancellation fees. Your plan stays active until the end of the current billing cycle, so you never lose time you already paid for.
What is a credit?
A credit is the unit measuring tool usage on DNS Checker. A single DNS Inspector query costs 1 credit. A WHOIS lookup costs 1 credit. SPF, DKIM, DMARC, and MX checks are free (0 credits). Each plan includes a set number of credits per month, and top-up packs that never expire can be purchased separately.
How many credits does a lookup cost?
Most single-domain lookups cost 1 credit. Tools that require heavier processing, like scanning multiple ports or searching across millions of records, cost more to reflect the additional resources involved. Some lightweight checks are completely free. The exact credit cost is shown on each tool before running a lookup. Rate limits are also in place to keep the platform fast and fair for everyone.
Do unused credits roll over?
Monthly subscription credits reset each billing cycle. Top-up credits never expire and carry over indefinitely.
What happens if I upgrade my plan?
Upgrades take effect immediately. You are only charged the prorated price difference for the remaining days in your current billing cycle, and your credit balance is reset to the full allowance of the new plan right away. For example, upgrading from Starter to Pro mid-cycle means you get 10,000 fresh credits instantly and only pay for the remaining days at the higher rate.
What happens if I downgrade my plan?
Downgrades also take effect immediately, but your current credit balance is preserved until the end of the billing cycle. Since you already paid for the higher plan, you keep using those credits until renewal. When the next billing cycle starts, your credits reset to the new plan’s allowance at the lower price. No credits are lost mid-cycle.
What payment methods are accepted?
All major credit and debit cards are accepted, including Visa, Mastercard, and American Express. Payments are processed securely through Stripe.
