NS on Risky TLDs

245,493 domains use nameservers hosted on risky TLD extensions (.buzz, .click, .club, .fun, .icu, .monster, .online, .pw, .quest, .rest, .site, .space, .surf, .top, .xyz). These nameserver domains are more likely to lapse, be abandoned, or be associated with abuse, creating a risk that an attacker could register the expired NS domain and take over DNS.
