Describe the Bug

Hi,
I am using _middleware in my project, and I want to access users ip address.
However, when I try to get it from request.ip it returns undefined.
What is the solution to this problem?

Here is a snippet of my code:

`export async function middleware(request: NextRequest) {
const ip = request.ip -----> returns undefined or null;
const city = request.geo -----> returns {};

const ip2 = request.headers.get('x-forwarded-for');
const ip3 = request.headers.get('CF-IPCountry');
}`

I was desperate, so I tried to get ip through request.headers, but this also doesn't work.
Is there another solution to get users ip address in middleware?

I also tried using service const response = await fetch('https://api.ipify.org/?format=json'); but this only returns server ip address, and not my real ip.

Also, i deployed the app, and ip still doesn't work: https://relock-front-stage.tbstaging.dev/

Please help :D

Expected Behavior

get user ip address after accessing request.ip

To Reproduce

in _middleware.ts try to access request.ip or request.geo
