Security hacker describe the most skilled. Newly discovered exploits circulate among these hackers. Elite groups such as Masters of Deception conferred a kind of credibility on their members. A script kiddie (also known as a "skid" or "skiddie") is an unskilled hacker who breaks into computer systems by using automated tools written by others (usually by other black hat hackers), hence the term script (i.e. a prearranged plan or set of activities) kiddie (i.e. kid, child—an individual lacking knowledge and experience, immature), usually with little understanding of the underlying concept.

Prefix delegation route. To solve this, RFC 6603 defines an optional mechanism and the related DHCPv6 option to allow exclusion of one specific prefix from a delegated prefix set.

For example, in a typical home network with legacy Internet Protocol version 4, the network prefix would be something like 192.168.1.0/24, as expressed in CIDR notation. With IPv4, commonly home networks use private addresses (defined in RFC 1918) that are non-routable on the public Internet and use address translation to convert to routable addresses
