How do i correct restart network-services in Debian?

Hello,

I would like to do follow steps.

Set a static IP-Adress on eth0 (For Testing)
Set DHCP on eth0
All steps should be done without a single reboot.

/etc/network/interfaces

Code:

  
   iface eth0 inet static
   address 192.0.2.7/24
   gateway 192.0.2.254

How do i perform the windows command "ipconfig /renew" on Debian ?

If i use "systemctl networking restart" -> "ip a" static ip doesnt show up
If i use "ifup eth0" -> "ip a" shows the correct ip address, why is this needed ? I never deactivated my interface eth0. This makes no sense to me i restartet the complete network service before.
What is the correct way to restart the network service ?

/etc/network/interfaces

Code:

  
   iface eth0 inet dhcp

How can i ask for a new ip form dhcp (what is the command)?
Do i need the "ifup eth0" here again ?

Regards,
Integer

NAME

       essidscan - scan for ESSID corresponding to available WLAN access points

SYNOPSIS

       In /etc/network/interfaces:

       mapping <interface> script essidscan

DESCRIPTION

       The essidscan utility is used to tell the ifup and ifdown utilities about the current SSID of the WLAN currently being accessed.  It can be
       used to map the SSID name to an iface stanza.

CONFIGURATION

       A sample /etc/network/interfaces may look like this:

	  mapping hotplug
	    script /etc/network/essidscan
	    map SSIDONE  wlan-work
	    map SSIDTWO  wlan-work
	    map HOME

	  iface wlan-work inet dhcp
	    wireless-key     1234-5678-9ABC-DEF0-1234-5678-9A
	    wireless-keymode restricted

	  iface HOME inet static
	    address	     192.168.2.4
	    netmask	     255.255.255.0
	    gateway	     192.168.2.1
	    wireless-essid   HOME
	    wireless-key     s:somepassword
	    wireless-keymode open

	  iface DEFAULT inet dhcp

FILES

       /etc/network/interfaces
	      the interfaces definition file

       /etc/network/run/ifstate
	      a record of the current state of the interfaces, managed by ifup and ifdown
