Postman response body variable is an ip address

My response body returns this:

    "ServerList": {
        "192.168.88.128": {
            "encryption": "None",
            "host": "192.168.88.128"
        }

I’m trying to test for encryption using this:

const response = pm.response.json();

pm.test("Server Encryption Check", function () {
    pm.expect(response.ServerList.192.168.88.128.encryption).to.eql("None");
});

Can’t seem to find a way to be able to have that ip in the test without a syntax error.

>Solution :

You can reference the property as an indexer:

response.ServerList["192.168.88.128"].encryption
