Environment

Python version: 3.6.9
NetBox version: 59139502ac7d (v2.6.1)

Steps to Reproduce

Create a prefix without VRF (vrf = null)

{
            "id": 5,
            "family": {
                "value": 4,
                "label": "IPv4"
            },
            "prefix": "10.242.0.0/16",
            "site": {
                "id": 4,
                "url": "http://localhost:32768/api/dcim/sites/4/",
                "name": "mySite",
                "slug": "mysite"
            },
            "vrf": null,
            ...
}

Try to get this prefix by prefixes API with VRF filter to null
curl -H "Accept: application/json; indent=4" -H "Authorization: Token 0123456789abcdef0123456789abcdef01234567" "http://localhost:32768/api/ipam/prefixes/?vrf=null"
With vrf_id field filter, it works correctly

Expected Behavior

Same result with vrf filter as vrf_id filter when filter value is null

Observed Behavior

vrf=null filter does not filter anything

@jeremystretch commented on GitHub (Aug 15, 2019):

The vrf filter matches on an assigned VRF object's rd field, which is a character string that cannot be null. Thus vrf=NULL can't work. You'll need to use the vrf_id filter to filter prefixes with no VRF assigned.
