/God-zil' *-gram/ (From Japan' s national hero and datagram) 1. A network packet that in theory is a broadcast to every machine in the universe. The typical case is an IPdatagram 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 IPGodzillagram has 65,536 octets. Compare super source quench. (2003-10-07)
