Read
RFC 1597, "Address Allocation for Private Internets" to get the address ranges involved.
Read
"TCP/IP Illustrated" (3 Volumes) by W. Richard Stevens to find out how IP networking works.
Read the respective AIX manpages about
: mkdev, chdev, lsattr, lsdev, mktcpip and probably some others (netstat, no, ping, ...) to learn how to create and test lasting network interfaces/attributes.
Read the man pages of: route, ifconfig, and probably some others to learn about making changes to the network configuration which won't survive reboot.
I hope this helps.
