  2. Anycast - Wikipedia

    en.wikipedia.org/wiki/Anycast

    Anycast is a network addressing and routing methodology in which a single IP address is shared by devices (generally servers) in multiple locations. Routers direct packets addressed to this destination to the location nearest the sender, using their normal decision-making algorithms, typically the lowest number of BGP network hops.

  3. Internet Protocol - Wikipedia

    en.wikipedia.org/wiki/Internet_Protocol

    Anycast delivers a message to any one out of a group of nodes, typically the one nearest to the source using a one-to-one-of-many [4] association where datagrams are routed to any single member of a group of potential receivers that are all identified by the same destination address. The routing algorithm selects the single receiver from the ...

    In computability theory, an undecidable problem is a decision problem for which an effective method (algorithm) to derive the correct answer does not exist. More formally, an undecidable problem is a problem whose language is not a recursive set; see the article Decidable language.

    en.wikipedia.org/wiki/Session_hijacking

    In computer science, session hijacking, sometimes also known as cookie hijacking, is the exploitation of a valid computer session—sometimes also called a session key—to gain unauthorized access to information or services in a computer system. In particular, it is used to refer to the theft of a magic cookie used to authenticate a user to a ...
