A reverse NS API is a data consumption model that returns a list of domains connected to a nameserver used as an input. It can help understand if a nameserver is dedicated to a single individual or organization or if it is shared among several hosts.
All of the historical DNS API results come from a massive database that is updated daily. The database contains 500 billion historical lookup records, including more than 196 million nameserver records.
There is no need to worry about compatibility issues with reverse NS API. Our nameserver records come in well-known and widely used formats, including XML and JSON.
You may not be able to reach your target audience when you share nameservers with domains that are involved in malicious activities. Avoid getting blacklisted by using Reverse NS API to see what domains you share nameservers with.
