How do I find expiring domains with specific keywords?

DNS Checker provides keyword search across expiring domain names with three matching modes. 'Starts with' (the default and fastest mode) finds domains where the label begins with the keyword — searching 'solar' returns domains like solarpower.com and solarcity.net. 'Contains' finds the keyword anywhere in the domain label, so 'solar' also matches bestsolar.com or gosolarnow.org. 'Ends with' matches domains ending with the keyword, such as gosolar.com. The search operates on the domain label (the part before the TLD), matching only alphanumeric characters and hyphens. Domain length filters automatically adjust to be at least as long as the keyword. For example, searching 'solar' (5 characters) means the minimum domain length cannot be set below 5. All length limits conform to RFC 1035, which specifies domain labels between 1 and 63 characters.

Can I register an expiring domain directly?

DNS Checker is a domain intelligence platform, not a registrar — it provides expiry data and monitoring to help with research and timing. When a domain expires, it enters a 30-45 day auto-renewal grace period where the original owner can still renew at the standard price. After that, ICANN-accredited registrars must offer a 30-day redemption grace period with a premium recovery fee of $80-200. If nobody redeems it, the domain enters a 5-day pending delete phase and then drops. For desirable domains, manual registration attempts rarely succeed. Automated drop-catching services from SnapNames, NameJet, Pool.com, and GoDaddy Auctions submit registration requests within milliseconds of release. A backorder service or auction platform provides the best chance of acquiring a specific expiring domain.

What is domain backordering and how much does it cost?

Domain backordering is a service that watches a specific expiring domain and automatically attempts to register it the instant it drops after the pending delete phase. These services use distributed networks of registrar accounts and high-speed connections to submit registration requests within milliseconds of release. Major providers include SnapNames, NameJet, Pool.com, and GoDaddy Auctions. When multiple people backorder the same domain through one provider, it goes to a private auction among those backers. When multiple providers compete for the same domain, the outcome is a speed race determined by network latency and registrar processing time. Backorder fees range from $10-69 for the service, plus the standard registration price if the catch succeeds. Competition varies enormously — short domains and dictionary words attract dozens of backorders, while longer niche domains may have no competition.

What happens after a domain name expires?

A domain passes through four phases after its registration expires. Phase 1: Auto-renewal grace period (0-45 days, varies by registrar). The domain may auto-renew or the owner can manually renew at standard price. Phase 2: Redemption grace period (30 days for gTLDs, mandated by ICANN). The original owner can recover the domain at a premium of $80-200 above normal renewal. DNS resolution stops during this phase, taking any website or email offline. Phase 3: Pending delete (exactly 5 days). The domain is queued for release at the registry level — no renewal or recovery is possible. Phase 4: General availability. The domain becomes available for new registration at standard price. In practice, desirable domains are caught by automated backorder services within seconds of release.

What filters are available for expiring domain searches?

DNS Checker offers six filters for expiring domain searches. Days until expiry: preset ranges of 7, 14, 30, 60, or 90 days, or any custom value from 1 to 365 days. Keyword search: match text in the domain label with starts-with, contains, or ends-with modes. TLD filter: narrow results to a specific top-level domain like .com, .net, or .org. Domain length: set minimum and maximum character limits between 1 and 63 (per RFC 1035), automatically adjusted to the keyword length when a keyword is active. Minimum age: filter by domain registration age in years — older domains (5+ years) often carry more authority and backlinks. Results are sorted by expiry date with color-coded urgency indicators: red for 7 days or less, orange for 8-14 days, and yellow for 15-30 days.

Are expiring domains free to register?

Yes, once a domain completes the full expiry lifecycle and enters general availability, it can be registered at the standard registration price for its TLD — typically $8-15 for .com domains. However, 'free to register' and 'easy to register' are different things. High-value expiring domains (short names, dictionary words, exact-match keywords) are almost always caught by automated backorder services within seconds of release, requiring a backorder fee of $10-69 plus the registration price. Less competitive domains — longer names, niche keywords, or newer TLDs — may genuinely be available for standard registration. DNS Checker helps identify both types: use the keyword search and length filters to find domains matching specific criteria, then assess competition based on domain age, TLD, and name quality.

What Are Expiring Domains?

Expiring domains are registered domain names approaching the end of their registration period that the current owner has not renewed. When a domain's registration term ends, it enters a multi-phase expiry process governed by ICANN policies before becoming available for new registration. Domain investors and webmasters monitor expiring domains to acquire established names with existing authority, backlinks, and brand recognition at standard registration prices rather than premium aftermarket costs.

DNS Checker tracks over 184 million WHOIS records across 1,900+ top-level domains, refreshed daily via RDAP (Registration Data Access Protocol, defined in RFC 9082). This database enables keyword-based search, TLD filtering, and age-based discovery of domains entering the expiry window — from 1 day to 365 days before expiration.

What Are the Phases of Domain Expiry?

When a domain registration expires and the owner does not renew, it passes through four phases before becoming available. Each phase has different costs, recovery options, and risks. The timeline below applies to generic top-level domains (gTLDs) under ICANN policy — country-code TLDs (ccTLDs) may differ.

Phase	Duration	Recovery Cost	DNS Active	Who Can Act
Auto-Renewal Grace	0-45 days	Standard renewal price	Yes	Current owner only
Redemption Grace	30 days (ICANN mandate)	$80-200 + renewal	No	Current owner only
Pending Delete	Exactly 5 days	Not possible	No	Nobody
General Availability	Immediate	Standard registration ($8-15 for .com)	N/A	Anyone (first come, first served)

How Do You Find Valuable Expiring Domains?

Not all expiring domains are equal. The most valuable dropping domains share specific characteristics that indicate existing authority, brandability, or keyword relevance. Here are the key signals domain investors evaluate:

Domain Age (5+ years)

Older domains often carry more authority and backlinks. Search engines treat domain age as a trust signal, and a 10-year-old domain with clean history can provide immediate SEO advantage over a new registration.

TLD Quality

Premium TLDs like .com, .net, and .org command the highest resale values. A .com domain is worth 5-10x more than the same name on a newer gTLD. Country-code TLDs can be valuable for geo-targeted businesses.

Short Domain Length

Short domains (3-6 characters) are increasingly rare and command premium prices. One-word .com domains routinely sell for $10,000-$500,000+ on the aftermarket. Use the length filter to target specific ranges.

Keyword Relevance

Domains containing high-value keywords (e.g. 'solar', 'crypto', 'cloud') in growing industries are more brandable and SEO-friendly. Use keyword search with starts-with or contains mode to discover these.

How Does Keyword Search Work?

The keyword search filters expiring domains by matching text within the domain label — the part of the domain name before the TLD. Three matching modes are available, each optimized for different discovery strategies:

Starts with (default, fastest): Finds domains where the label begins with the keyword. Searching "solar" returns solarpower.com, solarcity.net, solarenergy.org.
Contains: Finds the keyword anywhere in the label. "solar" also matches bestsolar.com, gosolarnow.org, or mysolarpanel.net.
Ends with: Matches domains ending with the keyword. "solar" matches gosolar.com, buysolar.net, or cheapsolar.org.

Only alphanumeric characters and hyphens are matched, following DNS naming rules defined in RFC 1035. When a keyword is entered, domain length filters automatically adjust so the minimum cannot be less than the keyword length — searching for "solar" (5 characters) means the minimum is at least 5.

Where Does the Expiring Domain Data Come From?

DNS Checker maintains a continuously updated database of over 184 million WHOIS records collected via RDAP (Registration Data Access Protocol), the structured successor to traditional WHOIS defined in RFC 9082 and RFC 9083. Expiry dates are extracted from the "events" array in RDAP responses where the eventAction is "expiration".

The data covers 1,900+ top-level domains and is refreshed daily through distributed RDAP workers that query registry and registrar servers. Each domain record includes the registration date, expiry date, registrar name, nameservers, and EPP status codes. This RDAP-based approach provides more structured and reliable data than parsing legacy WHOIS text responses, which vary in format between registrars and lack a standardized schema.

What Other Tools Help With Expiring Domain Research?

DNS Checker provides a suite of domain intelligence tools that complement expiring domain research. Use these together to evaluate domains before acquisition:
