I'm using netstat on Win XP to check protocol transmission details for TCP, IP, and ICMP. There is transmission only in TCP. No transmission in ICMP is understandable since it's for errors and I assume that there were none, but why is there no transmission through IP?

netstat -s shows per-protocol statistics, includng those for IP.
On my XP PC (see below) the IP Output Requests = ICMP messages sent + TCP segments sent + TCP segments retransmitted + UDP datagrams sent.
C:\>netstat -s
