What is Active Domain Search
DomainKits Active Domain Search indexes currently registered gTLD domains that are resolving and publicly accessible. Powered by the enterprise data pipelines of ABTdomain.com, the database covers 240+ million domains across 1,000+ gTLD extensions with daily updates and ongoing TLD-level analysis. Search results show domain name, TLD, for-sale status, cross-TLD registration count, and more for each domain.
When Domains Leave Active Domain Database
Domains leave the active database through two paths. When a registration lapses, the domain enters the expiration pipeline and becomes searchable in Expired Domain Search, where it can be backordered or recovered. If no one renews or claims it, the domain completes deletion and moves to Deleted Domain Search, where it can be registered at standard cost.
In some cases, a domain may become non-active due to registry holds, legal disputes, or the owner opting out of public indexing. These domains are not included in search tools.
How to Use Key Filters for Better Results
The following key filters help you narrow results to find exactly what you need.
Position
Where a keyword appears in a domain name reveals how the market uses it. "Start" position (e.g., aitools.com) means the keyword drives the domain concept. "End" position (e.g., myai.com) means it is used as a modifier. Comparing start vs end counts shows whether a keyword is used as a category anchor or a descriptor.
TLD
.com accounts for approximately 66% of gTLD registrations. When a keyword's .com concentration is significantly higher or lower than this baseline, it signals something about the keyword's market. High .com ratio suggests commercial validation. Spread across many TLDs suggests broader or more speculative interest.
For-Sale
Filtering by "For Sale" surfaces domains whose owners have listed them on marketplaces. In the active database, these represent the current secondary market inventory for a keyword. Combined with total count, the for-sale ratio gives a quick read on how much of a keyword's namespace is held by investors vs operators.
Type
Filter by character composition: Pure Alpha for letter-only domains, Pure Number for numeric domains, No Hyphen or No Number to exclude specific characters. Helps separate clean brandable names from bulk registrations.
Length
Filter by domain name length: under 5 characters, 5-10, 10-15, or 15+. Short domains are the scarcest and typically most valuable.
Active Domain Search vs Other Domain Search Tools
A domain name moves through a predictable lifecycle. DomainKits provides a dedicated search tool for each stage. Active Domain Search covers the longest stage, where domains spend most of their registered life.
| Stage | What It Covers |
|---|---|
| New Domains | Domains registered in the past 60 days. Track registration trends, spot for-sale opportunities, and analyze registration periods. |
| Active Domains | Currently registered gTLD domains. Full inventory search with pattern analysis and for-sale filtering. |
| Aged Domains | Registered domains with significant history. Filter by age and find for-sale listings with established domain history. |
| Expired Domains | Domains in the expiration pipeline (grace period, redemption, pending delete). Backorder and drop-catch opportunities. |
| Deleted Domains | Previously registered domains that completed the deletion cycle. Register dropped domains with prior history at standard cost. |
The lifecycle is a cycle: a deleted domain can be re-registered and re-enter as a new domain.
Privacy by design: DomainKits focuses on what happens to a domain, not who owns it. All searches operate on registration metadata, not personal data.
Frequently Asked Questions
What is the difference between Active and Newly Registered domain search?
Newly Registered Domain Search covers domains from the past 60 days only, designed for tracking registration trends and recent brand activity. Active Domain Search covers currently registered gTLD domains regardless of age, designed for market sizing, inventory analysis, and finding for-sale opportunities across the full namespace.
A domain shows "For Sale" in results. How do I proceed?
Domains flagged as for-sale include a direct purchase link in the search results. Click the link to view pricing and complete the acquisition on the marketplace.
Does this include ccTLD domains?
Active Domain Search covers gTLDs (.com, .net, .org, .xyz, .app, and 1,000+ others). ccTLD monitoring (.uk, .de, .cn, etc.) is available through BrandArgus for brand protection and specialized monitoring.
Can I set up automatic keyword monitoring?
For automated monitoring of specific keywords across new registrations, use the monitoring features available through NRDS or BrandArgus. Active Domain Search is designed for on-demand inventory queries.
Can I download the results?
Yes. Click "Export Results" after searching to download. Guest users have limited export access. See our Membership Tiers guide for details on each account level.
Does DomainKits collect domain ownership data?
No. DomainKits does not perform PII lookups or store personal ownership information. The platform is fully GDPR-compliant. All searches operate on registration metadata: dates, nameservers, TLDs, and status.
