When talking about brand reputation, one of the first things that come to mind is reviews. What are customers saying about your product or service? While that is true, there is more to a brand’s reputation than racking up positive reviews. We delved deeper into brand reputation in this post and provided some actionable tips and valuable tools to manage it effectively.
WhoisXML API’s website categorization products have been helping organizations determine the authenticity and reliability of sites by scanning the meta tags and content of more than 152 million websites. The machine learning (ML)-driven process allows organizations to detect suspicious domains, align their site categories with their marketing messages, and target the right leads, to name a few.
Today, the tools have been made more massive by adopting the classifications used by the Internet Advertising Bureau (IAB). IAB’s content classification taxonomy has become a standard in the industry, along with other solutions that aim to promote brand safety, ad fraud prevention, and consumer privacy.
Besides the number of categories, Website Categorization Lookup and Website Categorization API also have improved functionalities that provide users with much-needed accuracy and confidence.
WhoisXML API made its DNS database download available in six different files, each for different DNS record types. Doing so makes the DNS database files easier to integrate and analyze and enables particular use cases.
The resource records you can download as database files are:
This tutorial looks into the six types of DNS databases now available for download.
Passive DNS introduced by Florian Weimer in 2005 is now a central resource in IP security investigations, security of the operation of the domain name system (DNS), and many more. A Passive DNS database contains observed events whenever an IP resolves to a domain name in a DNS communication. Hence, it is a database independent from the current state as well as the physical infrastructure of the DNS itself. In addition, it contains time information: the date and time when such a resolution was first and last observed; this cannot be found out from the DNS.
One of the easiest ways to obtain such data is by using WhoisXML API's services. In the present blog, we focus on the reverse lookup: using an IPv4 address we want to reveal the domain names that these IPs belonged to on certain dates.
Privacy has become a top concern in the digital age, and online users often look for ways to keep their identity protected. One example of such privacy-related initiative is the use of disposable email addresses. This post takes a close look at this type of email address and discusses the following points:
In what follows, we’ll develop a small Python program based on WhoisXML API's email verification package, python-email-verifier that returns the valid and working abuse e-mail of an Internet domain if it exists.
In the first part of this blog, we demonstrated how to download data from WhoisXML API's daily data feeds right after their publication by using the recently introduced RSS feed as the activator of download. In particular, we showed how to download the list of domains newly registered in the .com top-level domain (TLD).
Now, to make the task a bit more interesting we demonstrate the use of our domain list with a showcase application: we calculate the list of the most frequent English words in the domain names on that day. This can be interesting in various applications. Domainers, for instance, can get information on the newest trends in domain registrations. Journalists and researchers can get a clue on a topic gaining popularity, etc.
This technical blog aims to demonstrate how to download data from WhoisXML API's daily data feeds right after their publication. Obtaining lists of newly registered domains and their WHOIS data can be critical in many applications. (We will showcase such an application in the second part of this blog.) Recently an RSS feed has been introduced for the service that informs about data publication immediately, which makes this easy. As a demonstration, we shall go through a particular task: download the list of domains newly registered in the .com top-level domain (TLD).
We will use a Linux system and its understanding requires intermediate programming and command-line skills. We will use BASH but it is also easy to modify for zsh, which is the default on Mac OS X. We assume Python, with pip and virtualenv.
