Koi usually live around 20 or 30 years. The oldest Koi on record was named Hanako. It purportedly lived to be about 226 years old. It lived in a pond that was in a stable area (read low geologic activity) and was passed down from generation to generation. Hanako died around 1977.
Â­ This is where NAT (RFC 1631) comes to the rescue. Network Address Translation allows a single device, such as a router, to act as an agent between the Internet (or public network) and a local (or private) network. This means that only a single, unique IP address is required to represent an entire group of computers.
A gateway is a data communication device that provides a remote network with connectivity to a host network. A gateway device provides communication to a remote network or an autonomous system that is out of bounds for the host network nodes. Gateways serve as the entry and exit point of a network; all data routed inward or outward must first pass through and communicate with the gateway in order to use routing paths. Generally, a router is configured to work as a gateway device in computer networks.
