: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
65,536 octets. Compare {super source quench}.
