I think so, I am not a bsd expert, but http://www.openbsd.org/cgi-bin/man.cgi?query=inet6&apropos=0&sektion=0&manpath=OpenBSD+Current&arch=i386&format=html#PROTOCOLS For security reasons, OpenBSD does not route IPv4 traffic to an AF_INET6 socket, and does not support IPv4 mapped addresses, where IPv4 traffic is seen as if it comes from an IPv6 address like ::ffff:10.1.1.1. Where both IPv4 and IPv6 traffic need to be accepted, listen on two sockets. man page: IPV6(7) Linux Programmer's Manual 2011-09-08 ... IPv4 connections can be handled with the v6 API by using the v4-mapped-on-v6 address type; thus a program only needs to support this API type to support both protocols. .... I know only, this makes things more complicated. May be you generally use two sockets - this makes the linux-version more complex, or you let decide bootstrap / configure and write different code for bsd and linux.
