IPv6 in IpWhiteList Middleware

Traefik Traefik v2 (latest)

Hi there!

I created a middleware configuration like this:

[http.middlewares]
  [http.middlewares.office-ipv6.ipWhiteList]
    sourceRange = ["2a3b:1:3:/52"]

HTTP Forbidden is the only response I get from traefik.
Is IPv6 actually supported in the ipWhiteList middleware?
