Assume "less /etc/network/interfaces" shows you something where you
can see...

iface eth0 inet static
        address 192.168.0.72
        netmask 255.255.255.0
        gateway 192.168.0.1

...which means that whenever your system boots up your computer will
have 192.168.0.72 as its IP. If you do a "dhclient" as mentioned above
you probably get a new IP from some DHPC-Server somewhere in your
network.
Maybe this is what is going on on your system.

I did not understand what you meant in (2) and (3).
