Suggestion - Sub Domains

Hi, Have you considered collecting and processing subdomains as well? Incorporating subdomains could significantly increase the number of detections. From my analysis of host records in my feeds, many only appear in Google Safe Browsing when accessed via their subdomains. There are several established methods for gathering subdomains from a top-level domain (TLD), such as the tool available at https://subdomainfinder.c99.nl/.
