Full-Lifecycle Domain Search Coverage

A domain name moves through distinct stages: it is registered, built out or parked, aged over decades, listed on the aftermarket, or left to expire and drop back to the public pool. Instead of forcing every query into one generic lookup box, DomainKits gives each stage its own search engine, eight in total, so you can apply the exact filters that matter for that stage.

Search vs. Tools: Discovery vs. Investigation

Use Search when you start with a keyword or pattern and want to discover matching domains across millions of records. Use Domain Tools (WHOIS, DNS, Reverse NS, Typosquat Scanner, Safety Check) when you already have a specific domain, IP, or nameserver in mind and want to investigate it in depth.

Frequently Asked Questions

Which domain database should I search for my goal?

Rather than searching all eight databases at random, pick the engine that matches what you are trying to accomplish:

To Register or Acquire a Domain Name: Start with TLD Search to check if your exact keyword is open across 1,200+ extensions. If you want a name with prior history, search Deleted Domains for recently dropped names at standard registration cost, Expired Domains for upcoming drops, or Marketplace for names already listed for sale.
To Spot Market Trends & Emerging Niches: Use New Domains (NRDs) to see which keywords are being registered over the past 60 days, or Active Domains and Aged Domains to measure long-term keyword adoption across 360M+ existing registrations.
To Monitor Brands & Infrastructure: Combine New Domains (to catch newly registered lookalikes) with Hostname Search (to see the latest hostnames and subdomains carrying your keyword).

How do I cut millions of keyword matches down to actionable domains?

Typing a popular root word like "pay" or "cloud" can return hundreds of thousands of domains. Across our search engines, four core filtering heuristics help isolate high-signal names:

Cross-TLD Registration Count: Most search results show how many TLD extensions share that exact domain label. Sorting by high Cross-TLD count surfaces established global brands and high-demand keywords; filtering for low counts helps find untapped niches.
Keyword Position (Start vs. End): Pinning your keyword to the start (prefix) or end (suffix) of the domain name reveals how the market structures brands in your niche and strips away irrelevant middle-string matches.
Character Composition & Length: Applying Pure Alpha (letters only), No Hyphen, and a length cap removes many automated bulk registrations and long descriptive phrases.
Commitment & Status Signals: Filtering by multi-year registration periods (in New Domains) or for-sale status separates serious commercial assets from speculative throwaways.

How often are the eight domain databases updated?

Update frequency follows how fast each stage of the domain lifecycle moves:

Newly Registered Domains (NRDs): Typically refreshed every 15 minutes across 1,400+ TLDs, built with actual registration dates rather than discovery dates.
Expired & Deleted Domains: Statuses are refreshed as registries publish updates.
Active, Aged & Marketplace: Each search page shows the date of its latest update.
Hostname Search: Results list the latest hostnames first.

Can I automate searches or receive email alerts when new matches appear?

Yes. With a free account, you can add an email alert to a keyword search in New, Expired, or Deleted Domains and get an email when new matches appear. For developers, security teams, and AI workflows, DomainKits data is also available through the REST API, MCP server, Agent Skills, n8n node, and Python SDK.
