using nfs network path as a kubernetes persistence volume

You asked for best practices and from what I've found I think that the best option would be white-listing the IP addresses. Since you do not want to do that, there are also some workarounds answers posted on SO created by people who had similar issues with dynamic IP clients in NFS. You can find a link to deployment using glusterfs in the posted answers. If you want NFS with dynamic IP (because it can change), you can use DNS names instead of IP. If you need dynamic provisioning, use glusterfs.

I will add some information about the volumes as you asked. Might give you some light on the topic and help with the issue.
Since pods are ephemeral you need to move the volume outside the Pod - therefore making it independent from the Pods - so the volume would persist its state in case of Pod failure. Kubernetes supports several types of Volumes.
You could use NFS (more on NFS in the previous link) - so after the Pod is removed the volume gets unmounted, but it still exists. This is also not desired in your situation as the user needs to know the file system type and other details about the volume it will want to connect to. When you go to the examples in the documentation about NFS yaml files, you will see that their kind is defined as a Persistent Volume Claim.
This method is based on creating a series of abstractions that will allow a Node to connect to the Persistent Volume, but the user will not need any backend details, in addition, your node can connect to many providers.
