Reverse IP/DNS API can be used for cybersecurity. So if your security solution flags a malicious IP address, Reverse IP/DNS API will tell you the domains connected to it.
Apart from enhancing cybersecurity, reverse IP/DNS API also helps with website administration, marketing and sales, and brand protection. For more information and illustrative examples on using Reverse IP/DNS API, access this product-specific blog.
The data you get from Reverse IP/DNS API is also obtainable via:
Reverse IP/DNS API is connected to a massive passive Domain Name System (DNS) database that contains data on 2+ billion hostnames and hundreds of billions of DNS-related events. That lets users know all the domains that resolved to a particular IP address over time. If any of the said domains are malicious, companies that employ IP-level blocking may include a connected IP address in their blacklists.
