Deployment Type

Self-hosted

NetBox Version

v3.7.1

Python Version

3.10

Steps to Reproduce

1. Create sample prefix. In my case the sample prefix ID is "645"

3. Create sample contact role named "Sample Contact Role"
4. Click on "Contact Assignment" option:
   
5. Then add the following text with the "Import" button:
   content_type,object_id,contact.id,role
   'ipam.prefix',645,25,'Sample Contact Role'

Interestingly, this process works fine when trying the same approach to import a contact to a device, as seen here:

Assigning a contact to a prefix is not currently supported. There is a feature request open to implement this; please see #13764.
