question on IP alias/broadcast

[J.D. Bronson]

I setup an alias statment in rc.conf and it seems to work fine..
but I have a question on the broadcast IP:


em0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
options=3<rxcsum,txcsum>
inet 192.168.100.1 netmask 0xffffff00 broadcast 192.168.100.255
inet 192.168.100.4 netmask 0xffffffff broadcast 192.168.100.4
ether 00:a0:9d:23:0b:f6
media: Ethernet autoselect (100baseTX <full-duplex>)
status: active


Why isnt the alias broadcast set to .255 ?

I didnt explicitly set the broadcast in rc.conf, and while I could I wanted to see if I should?!

Thanks!
