The use case document on managing and remedying IP Blacklisting deep dives into a simple yet effective approach towards preventing the blacklisting of IP ranges managed by telcos and whitelisting them post-facto.
IP Addresses are monitored by multiple external blacklist providers for malware, spam, and other malicious activities. If an IP does have persistent malicious activity (each provider has its own criteria for categorizing such activities) these blacklist [aggregators] providers place the IP on their blacklist. These blacklists are used by many enterprises to block IP addresses to protect their networks from potential malicious activity.
Each day, many the telco’s IP addresses are blacklisted (sometimes up to 0.05% of the IP pool per day) by one or many of these blacklist providers. This blacklisting could be because a telco subscriber advertently or inadvertently participates in an activity that is deemed malicious. These could be a deliberate activity wherein, for instance, a subscriber sends multiple mass emails resulting in the generation of spam or inadvertently because the device being used by them on the telco’s network is infected by malware.
Irrespective of whether the act is intentional or not, the IP does get blacklisted and all subscribers of the telco that get natted on the IP are affected as their services get curtailed leading to customer experience and service accessibility issues. This also impacts their IP reputation.
