The abuse.net contact database contains the best contact addresses we know to report abuse coming from Internet domains. (It only keys on domains, not IP addresses.)

Although the database contains hundreds of thousands of entries, that's only a tiny fraction of the millions of domains that exist. If you know contact info for a domain that's not listed, or you discover better contact info than what's already there, please send it along so we can update the database.

Mail new and updated contact info only to update@abuse.net. Please set your mail program to send plain text rather than formatted or HTML mail, since the formatting often defeats our system's ability to decode it. (If you have a question, comment, or anything other than domain contact information, please see the abuse.net home page.)

The format our system understands is the name of the domain, a colon, and the reporting address(es) separated by spaces, all on one line:

example.com: abuse@example.com
example.org: jonp@example.com postmaster@example.net

Please note that the preferred format has spaces between the addresses, not commas. Do not put any commas into your entries, since they will just confuse the program that handles them and delay your update.

You can send info for as many domains as you want in a single message. If there's more than one contact address for a domain, we send copies of mail to all of them. Don't use mailto: URLs or any other extra punctuation. The entry for a domain automatically includes subdomains so if the contact info for, say, mail.example.com is the same as for example.com there's no need to send separate entries.

Please say if you're providing info on domains you're responsible for, or for ones you've researched. If the connection between a domain you've researched and the contact isn't obvious, tell us how you found it. If you send updates in the format described above, they will usually be processed automatically and added to the database within a few hours. Otherwise they will be handled manually after a possibly lengthy delay. We manually review the automatic submissions as well, and undo the bogus ones.

When our information for a domain comes from other than the domain's management or upstream ISP, we forward messages to the listed address(es) as well as to postmaster@domain, on the theory that postmaster remains the standard contact address unless the domain owner tells us otherwise.

Please send only entries for domains, not numeric IP addresses. We keep no database of IP addresses, so info about IP addresses is discarded.

Note: It is not necessary to register at abuse.net to submit entries for the database, although you're always welcome to do so, and registration does not affect the contact database in any way. Database listings are provided without charge, and we neither solicit nor accept contributions.

You don't.

Abuse.net is not a feedback loop. Do not send any information about IP addresses, since we keep no database of IP addresses. Do not send any requests to be added to our feedback loop, since we are not a feedback loop.
