A domain name checker answers one question, is this exact name registered under this extension or not, and it answers it by querying the registry that owns the extension. That sounds simple, but the results are misleading more often than most people expect: two checkers disagree, "available" turns into a ₹40,000 premium at checkout, and a name that was free on Tuesday is gone by Thursday. This guide explains how the check actually works, what each result means, what .in, .co.in, and .com really cost in rupees as of September 2026, and an honest comparison of the free tools you can use, including ours.
For the short practical checklist, our earlier post on checking domain availability in India still applies. This one goes into the mechanics.
How an availability check actually works
Every extension has a registry. Verisign runs .com and .net; NIXI (the National Internet Exchange of India) runs .in, .co.in, .net.in, and the Indian-language extensions; .shop, .store, and .online belong to other registry operators. The registry holds the authoritative list of what is registered, and anyone can ask it.
Checkers ask in one of four ways:
- RDAP, the Registration Data Access Protocol, is the current standard. It returns structured JSON with the domain status, creation and expiry dates, registrar, and nameservers. ICANN required all gTLD registrars and registries to support it, and since early 2025 it has replaced the old WHOIS port-43 service as the required protocol for gTLDs like .com.
- WHOIS, the older plain-text protocol, still runs for many extensions and is what NIXI's .in lookup and most registrar "WHOIS" pages use behind the scenes.
- Registrar availability APIs, which registrars use on their search pages. These are fast and check dozens of extensions at once, but they also carry the registrar's pricing logic, which is where "available, ₹39,999" surprises come from.
- DNS resolution, which asks a public resolver whether the name has any records. It is the fastest and needs no registry access, which is why quick checkers (including ours) use it, but a registered name with no DNS records will show as free, so treat it as a strong signal and confirm at registration.
A good checker, whatever it uses, tells you the status, not just a green tick.
How to read the result
- Available: no registration exists. Register it now; there is no reservation step.
- Available (premium): the registry or registrar has flagged the name as high-value and priced it above the standard fee. Two-letter, dictionary-word, and category names (loans.in, cakes.com) fall here. Renewals may also stay at the premium rate, so check before buying.
- Registered / Taken: someone holds it. The RDAP record shows the expiry date and the registrar, which tells you whether waiting is realistic.
- Reserved: the registry has withheld it. NIXI reserves certain names, and every registry reserves single letters and some two-letter strings.
- Pending delete / Redemption: the registration expired, the owner did not renew within the grace period, and the name will drop back to the public in a few weeks. This is what backorder services watch.
- Not offered here: the checker does not sell that extension, which is not the same as taken. This is the usual cause of two tools disagreeing.
Search the exact string you want, with no spaces and no "www". Then search the obvious variants, the plural, the hyphenated version, and the same name under the extensions you would be unhappy to see a competitor hold.
What domains cost in India, approx.
Prices vary by registrar, promotion, and the rupee-dollar rate, so treat these as September 2026 ballparks and check at checkout:
- .in: approx. ₹499 to ₹899 for the first year (promotions dip lower), approx. ₹699 to ₹999 on renewal. The best default for an Indian business that sells in India.
- .co.in: approx. ₹299 to ₹599 first year, approx. ₹500 to ₹800 renewal. Fine if the .in is taken, though customers increasingly type .in.
- .com: approx. ₹799 to ₹1,200 first year, approx. ₹1,200 to ₹1,600 renewal. Verisign's wholesale price rises most years, and Indian registrars pass it through. Worth it if you sell outside India or want the safest brand.
- .shop, .store, .online, .site: often ₹99 to ₹299 in year one and ₹2,000 to ₹3,500 on renewal. The first-year price is a hook; budget for the renewal.
Most Indian registrars quote these inclusive of 18 percent GST; some add it at checkout. Multi-year registration locks the price and, for .com, buys protection from the annual increase.
If the name is taken
You have four realistic moves, in order of cost.
- Pick a variant. Add your city, a verb, or a category: sharmadental.in, getsharmadental.in, sharmadentalclinic.in. The domain name generator produces hundreds of variants and shows which are free. Our guide to picking a domain covers what makes a variant strong rather than forgettable.
- Check the expiry. If the RDAP record shows it expires within a few months and the site is dead, set a backorder with a registrar and wait. Success rates are modest, but the cost is near zero.
- Buy it from the owner. Parked domains usually list a contact. Expect Indian aftermarket prices from a few thousand rupees to a few lakh for a strong dictionary name. Use an escrow service; never wire money first.
- Choose a different extension. If you are an Indian business and only the .com is taken, the .in is usually the right answer, not a compromise.
Do not fall for "domain front-running", the belief that searching a name causes the checker to buy it. Accredited registrars are prohibited from doing this, and there is no evidence any major one does. What does happen is that good names get registered by other people every day. If the name is free and you are sure, buy it in the same session.
Transfers, briefly
You are not stuck with the registrar you bought from. A .com can be transferred after 60 days from registration or a change of registrant; you unlock it, get the authorisation code, and approve at the new registrar. The transfer adds a year of registration and costs roughly one year's renewal. For .in, NIXI's rules are similar: the losing registrar must issue the auth code, and transfers are typically done within five days. Keep your registrant email current, because every transfer confirmation goes there.
Free domain checker tools compared
Honest notes on each, including ours.
- Neweb domain checker (/pages/domain-checker): checks .com, .in, .co.in, .shop, .store, .org, and .net in one search in about a second, with no login, no limit, and no upsell. It is a DNS-based check, so it is a fast first filter rather than a registry query: a registered name with no DNS records can show as free, and it does not show expiry dates or the current registrar. Neweb plans include a domain free for the first year, and the authoritative registry check runs before you are charged.
- Registrar search pages (GoDaddy, Hostinger, BigRock, Namecheap, and others): the widest extension coverage and the only place to see the actual price you will pay. Downsides: heavy bundling, promotional pricing that hides the renewal rate, and premium listings mixed in with standard ones. Use them for the final price check.
- RDAP and WHOIS lookups (ICANN Lookup for gTLDs, NIXI's WHOIS for .in, rdap.org for anything): authoritative status, expiry, and registrar. No prices, no suggestions, and the interface assumes you know what you are looking for. Use them when a checker says taken and you want to know for how long.
- AI or brandable name generators: useful for ideas, unreliable for availability. Always confirm the result on a registry-backed checker before you get attached to a name.
The practical workflow: generate a shortlist, run it through a fast checker to eliminate the taken ones, confirm the status of any near-miss with RDAP, then buy at whichever registrar shows the best renewal price, not the best first-year price.
Frequently asked questions
Why does one checker say a domain is available and another says it is taken?
Usually the "taken" tool does not sell that extension, or the "available" one is showing a premium listing. Confirm with an RDAP or WHOIS lookup, which reads the registry directly.
Is a .in domain better than .com for an Indian business?
For a business whose customers are in India, .in is cheaper, more likely to be available, and signals a local business in search. Take the .com too if you can afford both and plan to sell abroad.
Can I check who owns a domain?
Partly. RDAP shows the registrar, dates, and status, but contact details are redacted for privacy under most registries since 2018. Many registrars offer a contact form that forwards to the owner.
How fast can someone else register a name I searched?
Instantly. There is no hold after a search. If you find a free name you want, register it in the same sitting, even for one year.
What is a premium domain and should I buy one?
A name the registry or a reseller has priced above the standard fee because of its length or meaning. For most small businesses a clear, slightly longer standard-priced name at ₹500 a year serves better than a ₹50,000 one-word domain.
