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.
Without protocols, devices would lack the ability to understand the electronic signals they send to each other over network connections. Network protocols serve these basic functions: address data to the correct recipient(s) physically transmit data from source to destination, with security protection if needed.
