`64.79.89.0` and `64.79.85.0` are `/24` at max. The `/19` that covers them (and more) would be `64.79.64.0/19`.

@TomYan Thank you, these are XLHOST Ip ranges which are known to be malicious. Those ranges are all over the internet, I am not sure why they were shared wrong like this. You can check they were also shared like /19 in this post too https://stackoverflow.com/questions/29736449/how-to-block-access-by-ip-using-htaccess

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
