Hi All,
When describing the "alias" parameter ifconfig manpage claims that "If
the address is on the same subnet as the first network address for this
interface, a non-conflicting netmask must be given. Usually 0xffffffff
is most appropriate."
Taking into account that FreeBSD supports aliases from the same subnet
with identical netmask for 6+ years now, does this statement still make
sense? And what does this "conflicting netmask" stand for (I mean in the
context of more or less recent FreeBSD versions, say 8.0+)?
Are there any drawbacks in setting aliases like this:
ifconfig em0 inet 192.168.1.1 netmask 0xffffff00
ifconfig em0 inet 192.168.1.2 netmask 0xffffff00
instead of traditional:
ifconfig em0 inet 192.168.1.1 netmask 0xffffff00
ifconfig em0 inet 192.168.1.2 netmask 0xffffffff
(again, for more or less recent FreeBSD versions)?
