Getting Started

Getting started with the Abuse Contact DB

How do I query the Abuse Contact database?

The Abuse Contact Database is exposed via DNS.  This means you can send requests to the Abuse Contact DB the same way you would with a DNSBL or any other DNS-based list. This configuration permits a higher volume of queries than would be possible with an HTTP API.


To obtain the abuse contact for IP, you reverse the octets of the IP address and append ".abuse-contacts.abusix.zone."


$ host -t TXT descriptive text "abuse@hetzner.de"

The response contains the abuse contact in the TXT record.  

Multiple results are comma-separated in one TXT record.  If you do not get any result, the range or IP does not exist, or the responsible network owner doesn't declare an abuse@ role address.


IPv6 queries are also supported but require the lookup to be in "Nibble" format, which is the format used for IPv6 PTR record lookups.   You can find a tool to convert an IPv6 address to Nibble format here: http://rdns6.com/nibble

To obtain the abuse contact for the IPv6 address 2a03:b0c0:1:d0::bea:a001:


$ host -t TXT 1.0.0.a.a.e.b.
1.0.0.a.a.e.b. descriptive text "abuse@digitalocean.com"

Command-line Tool

A python-based command-line tool called "querycontacts" is available.

The tool provides a library for use in your Python programs.

You can install it via:

$ pip install querycontacts
Use the command "querycontacts <ip address>." This will convert an IP address, the subsequent abuse contact lookup, and return of the abuse@ address.
