In a captive portal, the firewall will make sure that only the DNS server(s) provided by the network's DHCP can be used by unauthenticated clients (or, alternatively, it will forward all DNS requests by unauthenticated clients to that DNS server). This DNS server will return the IP address of the captive portal page as a result of all DNS lookups.
DNS hijacking, DNS poisoning, or DNS redirection is the practice of subverting the resolution of Domain Name System (DNS) queries. [1] This can be achieved by malware that overrides a computer's TCP/IP configuration to point at a rogue DNS server under the control of an attacker, or through modifying the behaviour of a trusted DNS server so that it does not comply with internet standards.
He was the first American to be released from prison with a court sentence that banned him from using computers and the internet after his prison sentence.

DNS spoofing, also referred to as DNS cache poisoning, is a form of computer security hacking in which corrupt Domain Name System data is introduced into the DNS resolver's cache, causing the name server to return an incorrect result record, e.g. an IP address. This results in traffic being diverted to any computer that the attacker chooses.
Domain hijacking can be done in several ways, generally by unauthorized access to, or exploiting a vulnerability in the domain name registrar's system, through social engineering, or getting into the domain owner's email account that is associated with the domain name registration.
Levin stands trial in the United States and is sentenced to three years in prison. Authorities recover all but $400,000 of the stolen money. Hackers adapt to emergence of the World Wide Web quickly, moving all their how-to information and hacking programs from the old BBSs to new hacker web sites.
As a DNS provider, Dyn provides to end-users the service of mapping an Internet domain name—when, for instance, entered into a web browser—to its corresponding IP address. The distributed denial-of-service (DDoS) attack was accomplished through numerous DNS lookup requests from tens of millions of IP addresses. [ 6 ]
