Security hacker laws against computer hacking. Neal Patrick testified before the U.S. House of Representatives on September 26, 1983, about the dangers of computer hacking, and six bills concerning computer crime were introduced in the House that year. As a result of these laws against computer criminality, white hat, grey hat and black hat hackers try to distinguish themselves from each other, depending on the legality of their activities. These moral conflicts are expressed in The Mentor's "The Hacker Manifesto", published 1986 in "Phrack". Use of the term hacker meaning computer criminal was also advanced by the title "Stalking the Wily Hacker",
IPv6-to-IPv6 Network Prefix Translation DHCPv6. IPv6-to-IPv6 Network Prefix Translation IPv6-to-IPv6 Network Prefix Translation (NPTv6) is an experimental specification for IPv6 to achieve the address-independence at the network edge, given by network address translation (NAT) in Internet Protocol version 4. It has fewer architectural problems than traditional IPv4 NAT; it is for example stateless and preserves the reachability attributed to the end-to-end principle. However, the method still lacks solutions to translate embedding IPv6 addresses, for example in IPsec, and requires a more complex DNS setup (split-horizon DNS). One use case for IPv6-IPv6 Network Prefix Translation is multihoming for small networks; this may also be implemented
