     Note too, that we are not using examples that tell you to use -ipv4.address etc. These do not change the interface completely. In order to do that we need to set the ipv4.address and the ipv4.gateway to an empty string. Again, to save as much time as possible with our command, we are going to string them all together in one line:
 
     ```
-    nmcli con mod enp0s3 ipv4.gateway '' && nmcli con mod enp0s3 ipv4.address '' && nmcli con mod enp0s3 ipv4.method auto && nmcli con down enp3s0 && nmcli con up enp3s0
+    nmcli con mod enp0s3 ipv4.gateway '' && nmcli con mod enp0s3 ipv4.address '' && nmcli con mod enp0s3 ipv4.method auto && nmcli con down enp0s3 && nmcli con up enp0s3
     ```
 
     Running the `ip addr` command again, should show you the exact same results as when we ran the changes with `nmtui`. We could obviously do everything in reverse as well (changing our DHCP address to a static one). To do this, we would run the commands in reverse starting with changing the `ipv4.method` to manual, setting the `ipv4.gateway` and then setting the `ipv4.address`. Since in all of these examples we are completely reconfiguring the interface and not adding or subtracting values to it, we again would not use the examples out there that talk about using `+ipv4.method`,`+ipv4.gateway`, and `+ipv4.address`. If you used these commands instead of the ones we have used above, you would end up with an interface with *BOTH* a DHCP assigned address and a statically assigned one. That said, this can sometimes be very handy. If you have a web service listening on one IP lets say, and an SFTP server listening on another IP. Having a method of assigning multiple IP's to an interface is quite useful.
