The institution of slavery persisted for a long time in a number of colonies and dependencies. It was particularly widespread in Portugalâs African colonies as part of the plantation economy and as a household institution.
Network Address Translation (NAT) is an IETF standard that enables a local area network (LAN) to use one set of IP addresses for internal traffic and a second set of addresses for external traffic. All necessary IP address translations occur where the LAN interfaces with the broader Internet. NAT converts the packet headers (and in some cases the port numbers in the headers) for incoming and outgoing traffic and keeps track of each session.
NAT Overloading or Port Address Translation (PAT) is a modified form of dynamic NAT where the number of inside local addresses is greater than the number of inside global addresses. Mostly, there is just a single inside global IP address providing Internet access to all inside hosts.
