I am confused about zonal NEGs - particulary `GCE_VM_IP`.
I am looking at the following documents, parts of which i will cite in my query:
https://cloud.google.com/load-balancing/docs/negs/zonal-neg-concepts
In the following section, the doc says:
These (GCE_VM_IP) zonal NEGs contain one or more endpoints represented using the primary internal IPv4 address of a Compute Engine VM's network interface... Even though Google Cloud uses an IP address to represent the endpoint, the purpose of a GCE_VM_IP endpoint is to identify the network interface itself.
What does this even mean espesically the part that "the purpose of a GCE_VM_IP endpoint is to identify the network interface itself":
Even though Google Cloud uses an IP address to represent the endpoint, the purpose of a GCE_VM_IP endpoint is to identify the network interface itself. The network interface must be in the NEG's subnet.

I am unable to understand why to use a `GCE_VM_IP`. it seems that having a regular instance in an instance group should suffice.

Can you please help me connect the dots.
Thank you!
