Recommendation for aliases on an interface is to use 255.255.255.255 as the netmask on FreeBSD.

For example to add extra interfaces to lo0 on FreeBSD you may use:

  ipv4_addrs_lo0="127.0.0.2-5/8"
in rc.conf

And now those addresses are automatically assigned to lo0, the netmask will be set to 255.255.255.255 automatically for all but the first in that range (.2). Since 127.0.0.1 is unconditionally assigned to lo0, you could also use:

  ipv4_addrs_lo0="127.0.0.2-5/32"
This is what I do on FreeBSD.

The ifconfig man page just says the netmask must be "non-conflicting" if on the same subnet as the first network address for the interface (that'd be 127.0.0.1/8 for lo0). I'm presuming the narrower netmask qualifies as non-conflicting?
