Frequently Asked Questions
What is NS Reverse Lookup and how do I search domains on the same nameserver?
NS Reverse Lookup finds all domains that share a given nameserver. Enter any nameserver address (e.g., ns1.dan.com) and the tool returns every gTLD domain pointing to it. This is useful for analyzing domain portfolios, researching registrar usage, and understanding nameserver-level domain distribution.
How can I find short LLLL or NNNN domains on a nameserver?
After searching a nameserver, use the Filters. Set 'Length' to '< 5' and 'Type' to 'Pure Alpha' for LLLL patterns, or 'Pure Number' for NNNN domains. Combine with 'Sort by Shortest' to surface the most concise names first.
Can I use this for competitor portfolio analysis?
Yes. Many domain investors use custom nameservers for their portfolios. Searching that nameserver reveals the domains they hold, even when WHOIS privacy hides the registrant. You can then filter by TLD or keyword to analyze their niche strategy and portfolio composition.
Can I export the domain list to CSV?
Yes. DomainKits allows you to export your filtered results to CSV. The export respects all active filters, so you get exactly the subset you need for offline analysis.
How comprehensive is the NS database?
The Reverse NS database covers 240M+ active gTLD domains across 1,200+ extensions. Records are updated daily. Note: the database covers gTLD domains only; ccTLD domains (e.g., .uk, .de, .cn) are not included.
The domain I'm looking for is already taken. What can I do?
Search our domain databases for alternatives:
- Expired Domains: find domains that owners didn't renew and may become available soon.
- Deleted Domains: browse domains that have been fully released and are open for registration.
- TLD Search: check the same name across 1,200+ extensions to find an available match.
