Multiple IP Addresses?

Zone Alarm detected a new network after i updated it. I know since I have a router it has its own network address. However when I click the LAN connection it displays an IP address exactly the same as the one in Zone Alarm except for the number it ends in is a different number than the one in the Zone Alarm trusted zone. Is this normal?

I disabled the LAN connection and the network disappeared in Zone Alarm so I then re-enabled it and the network came up again. Doesn’t this mean I have nothing to worry about? Like I said the LAN IP is the same except for one number when displayed in Zone Alarm and in properties of the LAN connection.
