Unable to bind to IPv6 address

[data-niklas]

Hi,
I am using nix-serve-ng in a flake. Setting services.nix-serve.bindAddress to any IPv6 address fails. I assume that the parser finds the port by parsing until it detect a ::

nix-serve-ng/src/Options.hs

Line 228 in f3931b8

parseHost = do

Maybe the parser could detect a [ and then skip the : check until it detects the matching ] of the IPv6 address.

(I am trying to bind to the IPv6 interface of a VPN)

Thanks.
