Could you include the backtrace (should have been emailed hopefully if you configured that)?

Netbox 2.9.7 from official docker image. the IP in question has NAT, and was created in a previous Netbox version (2.9.4, probably). other IPs do not trigger this error.

[jeremystretch]

I'm not able to reproduce this behavior on v2.9.7 using the information provided.

I have the same problem

Python version: 3.6.9 NetBox version: 2.9.8

Steps to Reproduce :

1. Create a device without rack reference, add an interface to this device
2. Create an IP address "IP_In" referencing the newly created interface as Assignment
3. Create an IP address "IP_Out" referencing an the IP address "IP_In" as its NAT inside "By IP"
4. Edit the newly created IP address "IP_Out"

Expected Behavior : User should be presented with the IP edit form

Observed Behavior : An AttributeError exception is raised:

I guess it's related to https://github.com/netbox-community/netbox/issues/5022 and to nat_inside_parent.device.rack wich can be None
