Hmm, I just noticed, that the broadcast address then looks a bit
strange: 
	inet 149.237.200.100 netmask 0xffffffff broadcast 149.237.31.100

Should I then use the following command

	ifconfig vx0 149.237.200.100 netmask 0xffffffff broadcast 149.237.200.255 alias 

Or should alias IP adresses not broadcast at all ?

Thanks for further information. I hope this is not a RTFM question ;)
