The "Parasites - IPs" and "Malware Domain List (MDL) Feed - IPs" targets are being deprecated and will be unavailable for use after November 1st.  They are being deprecated due to the relatively high false positive incidence associated with IP address-based malware targets.

For our RPZ customers, we recommend adding the following domain targets to your RPZ policies: "Parasites - Domains" and "Malware Domain List (MDL) feed - Domains". These two targets will block malicious hosts at the domain level, providing a much lower rate of false positives while increasing protection.
