What I wondered was which CPU runs the IP stack.
Do you know? Is the source code where one can look it over?

The C128 has a Z80 and 8502 (6502 derivative) but they do not operate
simultaneously. The Z80 in the C128 is virtually only used for CP/M; very
little native mode software uses it. (Interestingly, it is the master
processor on bootup -- see
http://www.retrobits.com/ckb/secret/d128.html
). All other Commodore 8-bits are 6502-based only, although there is a
Z80 cartridge for the C64 to allow it to run CP/M 2.2.
