WHOIS

WhoisJson API usually pulls records from origin Whois servers in real time, so you get up-to-the minute results. We cache some records for performance, but you can bypass the cache as needed.

WELL-DEFINED FIELDS

Cleans up the records and pulls them apart into well-defined fields. Our system normalizes character sets and line endings, pulls the various fields from the raw text, and puts the fields in a consistent, automation-friendly format (XML or JSON).

AVOIDS QUERY RATE LIMITS

Avoids query rate limits that you would encounter when doing Whois queries from your own IP address. Our system uses caching and a large pool of diverse IP addresses to minimize blockages and ensure that you get the records you need.

What is a Whois Database Download?

A WHOIS database is a comprehensive or exhaustive set of data that any person can find on a domain. It has millions of WHOIS records that contain information related to a specific domain registered in any part of the world at any given point in time. Note that no website can exist without registering the domain it’s hosted on—it’s part of the law.

Why Would I Use Whois Database Download?

If you're a website creator and/or business owner, a Whois database download service or search may come in handy for you or your clients. As listed above, it may be an easy way to resolve issues related to intellectual or trademark issues you may come across with other sites or companies. This is especially important because if you are a victim of impersonation, the image of your brand is on the line and may suffer if left unattended. You will be surprised by the likelihood of such an event happening in the digital world, especially when threat actors can profit from it.

Furthermore, you may want to expand your web presence, so Whois could assist you in researching future domains. One way of doing this is by performing Whois lookups on the domain names you are interested in to check if they are available for purchase. If not, you can instead get information about the current owner, get in touch with them and see if they are willing to part with their domain.
