Abusive Hosts Blocking List

The AHBL is operated by a division of the Summit Open Source Development Group (SOSDG), a developer of open source technologies. Based on data pulled from various sources on the Internet, plus our own custom tracking tools and databases, the AHBL provides a highly useful database of known problematic machines on the Internet.

Unlike many of the other lists out there, the AHBL focuses on community involvement and communication. When contacting us, you get to speak to the same people who manage the database and who know its operations best.

The AHBL has been in operation in it's current form since October of 2003, and was previously known as the Summit Blacklist since late 2000. The AHBL is considered an evolutionary step in the SOSDG's spam fighting services.

Shoot On Sight Listings

    This IP address is listed for one of several reasons. The provider, individual, or company did one of the following:
    • Cart00ney threats made towards the AHBL, SOSDG, other blacklists, and spam fighters.
    • Attempted and unsuccessful legal attacks against the AHBL, SOSDG, other blacklists, and spam fighters.
    • Promotes, supports, or incites attacks against the AHBL, SOSDG, other blacklists, spam fighters, and others on the Internet.

    The SOS listings are also known as the 'cart00ney listings'. Once a provider is in the SOS listings, there is normally no way to have the IP space delisted. However, we do make exceptions to this policy under certain situations.

    Please note that SOS listings are considered 'sticky', meaning that they will follow the person/individual/company/ISP being listed no matter where they go, or if they change IP space.
