The problem here is that there are a number of older implementations that don't support the flag
=> this does not matter because of conditional compilation. and there is no way of turning the v4-mapped support off unless you downgrade. => there is no need of turning the v4-mapped support off if the second/to-0.0.0.0 bind() can fail safely. Then again, upgrading is nowadays quite a normal cycle... => I know but this does not help to get an answer to my question. Regards [EMAIL PROTECTED] PS: BTW IMHO the Symbian API implements an abstract "IPv6 is a new version of the Internet protocol". I have only a little concern because it implements too "the network protocol is the Internet protocol" (:-)! -------------------------------------------------------------------- IETF IPv6 working group mailing list ipv6@ietf.org Administrative Requests: https://www1.ietf.org/mailman/listinfo/ipv6 --------------------------------------------------------------------
