The technoirc.org DNSBL Blacklist was a public Domain Name System Blacklist (DNSBL) that focused on listing IP addresses. This particular blacklist (or blocklist) ceased its operations around 2013, which means it is now defunct. While it was active, it served as a resource for mail server administrators to block emails originating from IP addresses that were believed to be sources of spam or other malicious activities. Because it is no longer maintained or updated, its use in modern email filtering systems is non-existent.
The blocklist was operated by the organization Technoirc.org. Information about the organization itself is scarce, as the project and its associated services were discontinued many years ago.
The impact of being listed on the technoirc.org DNSBL Blacklist is low, effectively zero. Since the blacklist stopped operating in 2013, mailbox providers and system administrators do not use it to filter incoming emails. If you find your IP address on this specific blacklist, it will not affect your email deliverability. Any mail server still configured to use this defunct blocklist is severely outdated and misconfigured, which is a rare occurrence.
It is not possible to request removal from the technoirc.org DNSBL Blacklist because the service is no longer active. The original delisting process is unknown, and since the infrastructure is offline, there is no one to process a removal request.
Given the defunct status of this blacklist, here is what you should do if you find your IP listed:
