Renew means renew the lease, the IP address will not necessarily change. You
will get the same IP as far as possible.
If you haven't had an IP lease for a long time (maybe days) then that IP could
be assigned to someone else and then you will get a different one.

You will get the same IP address with a new lease.

Because that's how DHCP usually works. The MAC address (Physical address) of
your network interface and your host name can all be used to identify your
equipment and re issue the same IP.

It depends on what control you've got over the DHCP server and whether or not
you can tell it to issue a particular IP to a paricular MAC/host

This is normal. Why do you want to change it?
Dynamic does not mean that you get a new IP address every time you connect, it
means that the IP address is assigned by DHCP.
DHCP will usually try to give you the same IP address as far as possible because
this causes minimum disruption to your connection.
