Determine infrastructure connections between hostnames and IP addresses using one of the biggest archives of Domain Name System (DNS) records today.
Reverse IP & DNS API lets you query up to 30 IPs per second so you can quickly identify which domains are connected.
Our Reverse IP & DNS API comes with code samples for easy integration in several programming languages. It’s also available as a Splunk Enterprise application.
A reverse IP & DNS API is an intelligence consumption model with data delivery via API calls. The API establishes which domains might be using the same IP to host their websites’ contents. It allows website owners to check if their IP address is shared or dedicated and serves several purposes.
Identify all potentially dangerous domains that share the same IP with known malicious websites.
Identify your attack surface by discovering all the hosts and IPs related to a given target website/IP address. You can also check if you have the same IP addresses as vulnerable websites with Reverse IP/DNS API. Further analysis is possible, too, with Reverse WHOIS API and Reverse WHOIS Search.
During or after an intrusion or incident, you can use Reverse IP/DNS capabilities to identify the attackers’ hostnames.
You can also use Reverse IP/DNS API to ensure that your website’s IP address is not being used by any other domain. That may lower your search engine ranking and move your site to a less reputable area of the Internet.
Hosting your website on a crowded IP address or one with a bad reputation due to malicious neighboring domains can negatively affect your website performance and how you are perceived on the web. It may even land you on a blacklist.
Our Reverse IP/DNS API enables you to conduct an inventory of all your websites or those of your competitors hosted on the same IP address. The API also helps with brand protection, as it can find other domains that potential attackers own and pinpoint otherwise-unknown related web properties that can cause harm.
