DNS & IP Tools provide tactical intelligence to the Security Operation Center (SOC). Penetration Testers use the tools to map the attack surface of a target. Blue teams benefit from quickly identifying areas of security weakness and during incident response. Collect information about IP Addresses, Networks, Web Pages and DNS records.

The information gathering tools here are a quick reference point. Pivot from the information found with these tools to perform deeper enumeration using port scanners, web page analysis and other more aggressive tools.

In addition to the online access there is also the option to query the tools via an easy to use API, Maltego transforms and a Chrome extension.

Free IP and Network Tools

Chrome extensionChrome Extension for Fast access to IP Tools.

Many of these tools are passive in nature with no packets sent to target IP ranges. For tools that do generate a small number of packets against target networks there are benefits from not being sourced from your own IP range. Particular helpful in investigations or red team testing where you may benefit from not being directly attributable.

To balance the Free availability of these tools against the need to minimise abuse; a number of limits exist on the Free access to the IP Tools. Queries are are available through the web forms on each tool page. In addition access is also available using the simple API.

Using the IP Tools API

The aim of offering these tools via an API is to streamline access to vital information, simplifying the process of evaluating an organization's network security.

The output from the API is basic text, you can access the API using curl, a web browser or a scripting language of your choice such as php or python.

Using the API is straight forward, the target system IP address or hostname can be added to the q= parameter. No key or sign-up is required to access the API.

If you are a registered user you can access an API key in the user dashboard. Access with the API key must use HTTPS.

Example request with curl and a valid API Key:
curl https://api.hackertarget.com/dnslookup/?q=hackertarget.com&apikey=plmoknijbuhvygvtrgedsfghhhhkjhkhfsk

Access to the AS Lookup API

These tools have been made available for adhoc lookups to assist in the security assessment process. There is a limit of 50 API calls per day from a single IP address as a Free user. As some of the data from cached resources there is no guarantee made for accuracy or reliability of this service. See the HackerTarget.com terms of service for more information.

Rate Limiting of API Requests

To ensure service reliability we have a rate limit that amounts to a maximum of 2 requests per second from a single IP address. If you exceed the rate limit you will receive a HTTP 429 response code from the API server.

API Usage and Quota Monitoring

The current users API quota and usage can both be monitored by examining the HTTP Headers of the response from the API endpoint. In the example below the curl -i command is used, this will display the HTTP Headers as part of the output. The x-api-quota reports on the current users API quota and the x-api-count shows the current API usage count for the day.
