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.
Routers inside the private network can route traffic between private addresses with no trouble. However, to access resources outside the network, like the Internet, these computers have to have a public address in order for responses to their requests to return to them. This is where NAT comes into play. Internet requests that require Network Address Translation (NAT) are quite complex but happen so rapidly that the end user rarely knows it has occurred. A workstation inside a network makes a request to a computer on the Internet.
