I have one. Sorry, it is in Pascal, but translates very easily to C++:

procedure TMyInterceptor.receive_request(const ri: IServerRequestInfo);
var
  pr: IPrincipal;
  a: IAny;
  addr: string;
begin
  pr := TPrincipalCurrent._narrow(
          Orb.resolve_initial_reference('PrincipalCurrent')
        ).get_principal;

  a := pr.get_property('peer-address');
  a.get_string(addr);
  writeln('Got request from "', addr, '".');
end;

On my machine it outputs something like 'Got request from
"inet:10.9.18.124:2239".'.

I was just about to reply "Don't know", but then tried the above interceptor
code inside a normal servant method. No problem - so I guess the answer is
sort of "Yes": I don't know another method, but you don't have to use
interceptors.
