How can I have a netmask like 255.255.255.128 for one jail and a netmask

hosts boot-time in /etc/rc.conf ?
I would like the /etc/rc.d/jail to create the network aliases according
to the jails respective network mask. I see that /etc/rc.d/jail sets the
netmask to 255.255.255.255 for all network aliases.
Hi :)
I'm pretty sure this is the same FAQ as seen in questions@ / net@ wrt netmasks
of aliases. In short, if your aliased interfaces are in the *same* subnet as
your main IP (eg, the main IP's subnet includes all the aliased subnets), they
will be /32.
Thanks for your answer Norberto :-)
If I understand you correctly, you are saying that the same netmask as
the one for the hosts main IP will apply to all jails and therefore
there is no need to specify a netmask other than /32 for each jail in
the same subnet.
But this is not my case. I have two different subnets in the same
IP-range with different netmasks (of course) and also another IP-range.

192.168.1.0 /25 192.168.1.127 255.255.255.128
192.168.1.48 /28 192.168.1.62 255.255.255.240
192.168.2.96 /27 192.168.2.127 255.255.255.224
I'm trying to configure jails to run in all three subnets on the same host:
mainHost 192.168.1.1/25
jailHostA 192.168.1.2/25
jailHostB 192.168.1.54/28
jailHostC 192.168.2.100/27
I guess the jailHostA is OK since it's running in the same subnet as the
mainHost. But how do I configure jailHostB and C without creating a
static aliased interface (in /etc/rc.conf) when all jails are started up
with netmask /32 (from /etc/rc.d/jail) ?
Thanks! :-)
