Abuse Contact Database (DB) is a proxy database service for people who want to report network abuse directly to network owners, without getting lost in the RIR whois databases or get rate-limited by whois servers. The database service is an easy-to-handle mechanism that allows you to look up abuse contact email addresses from which abusive content was sent, by searching for the originating IP address.
We query the information stored in the RIR whois record for the range in question. Where possible, our Abuse Contact Database will return an address which is declared as abuse contact. As a failover, the technical contact in the RIR record may be returned.
We use only the biggest by RIRs (ARIN, RIPE, LACNIC, APNIC, AFRINIC) allocated ranges and the abuse contact addresses. If you believe there is a problem with the data or something is going wrong, please let us know so we can update it in a timely fashion.
The Abuse Contact Database is DNS driven. Which means, that you can send requests to the Abuse Contact DB DNS server in the same way you would, with a RBL or any other DNS based list.
To obtain the abuse contact for IP 184.108.40.206 query abuse-contacts.abusix.org with the reverse IP:
# host -t TXT 220.127.116.11.abuse-contacts.abusix.org
The response contains the abuse contact in the TXT record:
18.104.22.168.abuse-contacts.abusix.org descriptive text “firstname.lastname@example.org”
Multiple results are comma-separated in one TXT record:
22.214.171.124.abuse-contacts.abusix.org descriptive text “email@example.com,firstname.lastname@example.org”
If you do not get any result, the range or IP does not exist or the responsible network owner didn’t declare an abuse contact yet.
The Abuse Contact Database also provides responses for IPv6 address queries.
To obtain the abuse contact for an IPv6 address query abuse-contacts.abusix.org like this:
Reverse the IPv6 address, see this Wikipedia article.

A python-based command-line tool called querycontacts is available which offers some convenience. Furthermore, it offers a Python library you can use in your own Python programs.
# pip install querycontacts
2. Perform your queries:
# querycontacts 18.104.22.168
# querycontacts 2001:4800:4860::8844
The service is free!
If you use the information for reporting, we only want you to put this small reference into every single report message, indicating you used the Abuse Contact DB to find the abuse contact address:
