uh, that might be ipfw-speak (I don't use or pretend to know ipfw) but ICMP is
NOT "part" of IP (that would defeat the whole purpose of using it as a control
protocol for IP). Look at /etc/protocols:

ip      0       IP              # internet protocol, pseudo protocol number
icmp    1       ICMP            # internet control message protocol
