As of Nitrogen2, the function to do this is wf:peer_ip/0. It doesn't seem to appear in any docs at the moment, but it does almost the same thing wf_platform:get_peername() used to.

wf:peer_ip/0 -> {A, B, C, D} | {A, B, C, D, E, F, G, H} 
%% example output: {127, 0, 0, 1}

You can get the remote peer's address using wf_platform:get_peername/0.

@spec wf_platform:get_peername() -> {ok, {Address, Port}} | {error, posix()}
    Address = {N1,N2,N3,N4} | {K1,K2,K3,K4,K5,K6,K7,K8}
    Port = int()
