Checking Domains
Input Methods
domTrace supports multiple ways to input domains for checking:
- Text Input: Type or paste domain names directly into the text area (one per line)
- File Upload: Upload a .txt file containing domain names (one per line)
- Bulk Processing: Process hundreds or thousands of domains in a single run
Note: File uploads are limited to .txt files only. Make sure each domain is on a separate line in your file.
Selecting TLDs
Choose from a wide variety of TLDs to check:
- Default TLDs: .com, .net, .org (available to all users)
- Custom TLDs: Add any TLD you want (PRO, ULTRA, and UNLIMITED tiers only)
- Popular Options: .io, .co, .ai, .xyz, .app, .dev, and many more

Configuring Check Options
Before starting, you can configure how domains are checked:
- Delay: Time between checks (in seconds). Higher delays reduce server load but take longer
- Parallel Workers: Number of simultaneous checks. More workers = faster checking (tier-limited)
- WHOIS Checking: Enable/disable WHOIS lookups for more accurate results
Important: Your tier determines the maximum values for delay and parallel workers. Check your tier limits on the
Pricing page.
Viewing Results
Real-time Progress
As domains are checked, you'll see real-time updates showing:
- Domain status (Available, Taken, or Unknown)
- Checking progress and statistics
- Time elapsed and estimated completion
- Pause/Resume/Stop controls

Understanding Status
Each domain will show one of three statuses:
- Available: Domain is confirmed available for registration
- Taken: Domain is registered and not available
- Unknown: Could not determine status (may be due to network issues or rate limiting)
Controlling the Check
You can control the checking process:
- Pause: Temporarily pause checking (you can resume later)
- Resume: Continue checking from where you paused
- Stop: Stop checking completely (results up to that point are saved)
Exporting Results
CSV Export
After checking completes, you can export your results:
- CSV Export: Download results as CSV file (UNLIMITED tier only)
- Log Download: Download detailed checking logs (UNLIMITED tier only)
Note: CSV export and log download are only available for UNLIMITED tier users. PRO and ULTRA tiers can save results history but cannot export to CSV.

Understanding Credits
How Credits Work
domTrace uses a credit-based system to track usage:
- 1 credit = 1 domain checked: Whether you check example.com or example.com + example.net, it counts as 1 credit
- Daily reset: Credits reset at 12:00 AM Pacific Time (PDT/PST)
- Persistent tracking: Credit usage persists across login/logout sessions
- Tier limits: Each tier has a daily credit limit (FREE: 100, PRO: 2,000, ULTRA: 6,000)

When you reach your daily credit limit, you'll see an alert message. You can either:
- Wait for the daily reset (12:00 AM Pacific Time)
- Upgrade to a higher tier for more credits
- Purchase additional credits (if available)

Frequently Asked Questions
How accurate are the domain availability checks?
domTrace uses multiple methods for accuracy including DNS lookup and WHOIS queries. While we strive for 100% accuracy, domain registration status can change rapidly. Always verify availability directly with a registrar before purchasing.
Can I check custom TLDs?
Custom TLD selection is available for PRO, ULTRA, and UNLIMITED tiers. FREE tier users are limited to default TLDs (.com, .net, .org).
What file formats are supported for upload?
Currently, only .txt files are supported. The file should contain one domain name per line.
What timezone are timestamps in?
All timestamps use Pacific Time (PDT/PST - America/Los_Angeles timezone), including domain check timestamps, credit reset times, and activity logs.
