Learn MoreGet a list of domain names that share a name server for cybersecurity, marketing, and IT purposes. Test our Reverse NS Lookup now. Download our product sheet to learn more.
A reverse nameserver lookup, also referred to as a reverse NS lookup, is a search for all of the domain names that share a nameserver specified as a search term. A reverse namerserver lookup allows to understand if a nameserver is dedicated or shared among several hosts.
Reverse NS Lookup’s outputs are accurate, comprehensive, and backed by our large DNS record database, with millions NS records updated every week.
Reverse NS Lookup’s reports are created in a matter of seconds and have shareable URLs for faster communication and decision-making.
An NS record specifies what DNS server is responsible for a given domain. It tells you which NS contains the actual DNS records of the domain of interest. In even simpler terms, an NS record tells Internet-connected systems where to go to find out what IP address corresponds to a specific domain.
NS record management is important as failure to do so can result in non-resolution (i.e., users can’t find your website). NS records must always be updated as well to ensure they point to the right pages. Threat actors may also try making unauthorized changes to these records to redirect your site visitors to malicious pages.
Yes, definitely. NS records can be used to identify your DNS zone. A DNS zone is that unique part of the DNS where your domain resides that is administered by a single manager. That manager could be a person, an organization, or a company who/that is responsible for maintaining the zone by maintaining control of its components, primarily authoritative NSs.
Uncover all historical associations between NS or other DNS records and domains or subdomains. Our data is well-parsed and complete with timestamps.
