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.

​
IPv4

To obtain the abuse contact for IP 78.47.241.202, you reverse the octets of the IP address and append “.abuse-contacts.abusix.zone.” Example
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

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 tools to convert an IPv6 address to Nibble format online. To obtain the abuse contact for the IPv6 address 2a03:b0c0:1:d0::bea:a001: Example

Command-line Tool
