>> aliases should have a netmask of 255.255.255.255, as seen in ifconfig(8)
> why?  i regularly use aliases with masks smaller than /32, on a 3.1
> system e.g:

well, it turned out that

if i
  boot with the alias netmask of 255.255.255.0
it does not work
  delete the alias
  ifconfig the alias with a /32
it still does not work

but if i boot with a /32 alias, it works!
