ip Token

The ip token contains a copy of an Internet Protocol header but does not include any IP options. The IP options may be added by including more of the IP header in the token. The token has two fields: a token ID that identifies this as an ip token and a copy of the IP header (all 20 bytes). The IP header structure is defined in /usr/include/netinet/ip.h. Figure A-12 shows an ip token.
