As most ISPs do not allow the user to assign IP addresses; the IP addresses are picked out from an IP Pool at the ISPs end. The following is a typical format of the ppp-secrets file: # Secrets for authentication using PAP # client server secret acceptable_local_IP_addresses Summary: The use of the fourth field is to _force_ the ppp server to assign the ip address provided in field. It is very unlikely (security matters), that ppp servers would allow a remote client to set the IP number they are to be given. Note: This PR can now be succefully closed after clarifying the issue regarding the fourth field of the /etc/pap-secrets file. If any one who is reading this followup-trail would like to clarify this with external sources, i would suggest you start out with http://www.linuxdoc.org/HOWTO/PPP-HOWTO/, which is a good source on PPP related information.
