    Software version disclosed
    Nameservers · These nameservers report their software version via version.bind/version.server, which helps attackers find known vulnerabilities: ns1ak.dell.com: "41824.7"; ns1ns.dell.com: "2026.10.2"; ns2ak.dell.com: "41824.9"; ns2ns.dell.com: "2026.10.2"; ns3ak.dell.com: "48878.27"; ns3ak.dell.com: "48878.30"; ns3ns.dell.com: "2026.10.2"; ns4ak.dell.com: "41824.8"; ns4ak.dell.com: "41824.10"; ns4ns.dell.com: "2026.10.2".
