IPv4 Blacklist Reporting and Cleanup / Removal Pricing
Brander Group has expertise cleaning IPs and interacts with global IPv4 blacklist providers. We leverage our established relationships & reputation to remove dirty/blacklisted IPv4 addresses under most conditions.
Our service includes a detailed blacklist report which summarizes which IP addresses are blacklisted, which blacklist they are on and how many total IPs. We then can usually clean and whitelist most dirty IPs in around 1 – 10 days depending on the operator.
*While these are set prices for most situations, pricing may vary based on complexity and number of blacklists.
Proprietary Detailed IPv4 Blacklist Reporting
Brander Group understands the importance of IPv4 blacklist reporting and making sure our clients purchase a clean IP range. With that in mind, we make use of a proprietary IP blacklist software that checks every IPv4 address in an IP range against over 100 global blacklists. It then generates a report showing each blacklisted IP address, which IP blacklist it is on, and more importantly how to delist that IP address. Our software has the capacity to run an entire /16 IPv4 range (65,536 IP addresses) against over 100 global IP blacklists in 24 hours.
This is extremely helpful as we bring on new inventory because we work with our suppliers to help clean up all blacklisted IPs. This process can take several days, and our team works with the supplier to ensure the IP ranges are clean or close to it. We then provide this IP blacklist report to our clients as they prepare to purchase any specific IPv4 range.

Check your IP Range against a Global IPv4 Blacklist
The most common method for checking an IP range to determine if there are any IPs blacklists is to run each IPv4 address through an aggregating tool such as Mx Toolbox blacklist checker. They offer a solution that will check the IP address against over 100 global IPv4 blacklists, and report where the IP address is listed. If you have a few IP addresses, this is a great way tool to ensure you are safe.
However, how do you check a large IP range? While a /23 only has 512 IPv4 addresses in the IP range, that is over 500 different queries a person would have to run to determine that there are no blacklisted IPs in the entire IP range. Imagine having to do this over 65 thousand times for an entire /16 IP range. Short of having some interns working around the clock, there has to be a better way.
IPv4 Blacklist Significance
An IP range can easily get added to an IPv4 blacklist in today’s secure-conscious internet ecosystem. Because no matter how much security is added, we somehow all get victimized by spam. Whether you get the occasional spam email from a Nigerian prince asking for your bank account details, or a more severe malware phishing attack, we are all faced with having to protect against unwanted e-mails.
These scammers use a pool of IP ranges to get around server security settings that any company or user may have implemented. With so many scammers reaching users through different IP ranges, we needed a way to communicate these bad apples to the rest of the world to prevent further damage.
IPv4 Defenses are Born
In the early days, organizations were formed to help protect against these internet scammers. These organizations created a global database where someone could add an IP address and/or domain name to a global database. These are commonly referred to as a global IPv4 blacklist or domain blacklist. Popular email servers such as Microsoft and Google would use these global databases to help prevent spam mail from hitting any of their clients.
Of the hundred or so global IP blacklist providers, the 3 major players include Barracuda, Spamhaus, and Sorbs. If an IP address is listed on any IPv4 blacklist, it will likely affect an entire IP range from being able to send emails to other important internet-related functions.
