Reverse Name Server

Overview

The DomainTools API is organized into distinct products with queries that follow a RESTful URL structure wherever possible. Each product offers free, un-authenticated access for the sample URLs listed with each product. If you haven’t already, you may want to review the getting started document to learn about authentication and response formats.

The Reverse Name Server API provides a list of domain names that share the same primary or secondary name server. You can provide a domain name and the API will provide the list of domain names pointed to the same name servers as those listed as the primary and secondary name servers on the domain name you requested.

Reverse Name Server Parameters

Optional Parameters	Value
limit	Limits the size of the domain list than can appear in a response. http://api.domaintools.com/v1/domaintools.net/name-server-domains/?limit=10

Use the optional limit parameter to control the size of the result list.

If the domain_count response node is greater than the count of elements in the domain_list node, your query has been limited to only the first set of domains on that IP address, listed alphabetically. The limit may come from your service level or the limit parameter you set in your request.
