ip address with prefix length 32

[ciscoguy]

i am using dialup connection to connect to the internet .The isp assigns ip address with mask 255.255.255.255 and this its the gateway ip as well.

my question is how does this scheme works and how the client request is router to the isp

This is not unusual with dialup networks. You configure the dialer interface to use PPP and to negotiate and learn an IP address from the ISP. When the connection is established and negotiation is done the ISP assignes an address (with /32 prefix length) on the connection and assign a gateway address the same as the interface address. The client now recognizes that any request for a remote network access should be forwarded to the gateway interface, so it is sent to the dialer interface and is forwarded to the ISP on the other end of the PPP connection.
