Godzillagram: /god·zil'@·gram/, n.

[from Japan's national hero]

1. A network packet that in theory is a broadcast to every machine in the universe. The typical case is an IP datagram whose destination IP address is [255.255.255.255]. Fortunately, few gateways are foolish enough to attempt to implement this case!

2. A network packet of maximum size. An IP Godzillagram has 65,535 octets. Compare super source quench, Christmas tree packet, martian.
