Indeed: sendto() returns an invalid argument error, due to the fact that the broadcast address object's Length() method returns 0. I fix that issue r39605. But the DHCP server at work being quite unfriendly, I can't say if it fix the DHCP too. I notice that the local address is not anymore set to INADDR_ANY but 127.0.0.1. Maybe it doesn't help too. I'm not sure what to do about this second point, but for me BNetworkAddress::SetToWildcard() should not rely on the address resolver to do it, instead it should do explicitly, as for broadcast. At least for AF_INET family. Bye, Philippe.
