IPv6 aliases on FreeBSD 10

[pepe]

prefix 128 didn't work either. only first real address is working. none of
the aliases work with 48, 64 or 128...
our network is 2001:14b8:1801::/48 so that prefixlen 48 is right for ::1
address isn't it? and well, it works so
I think it is right...

And now it got even funnier. I added many aliases like this (copypaste from
ifconfig output so ipv4 addresses are there too):

        inet6 2001:14b8:1801:c001::2 prefixlen 48
        inet6 2001:14b8:1801:c001::3 prefixlen 48
        inet6 2001:14b8:1801:c001::42 prefixlen 48
        inet 62.165.159.203 netmask 0xffffffff broadcast 62.165.159.203
        inet6 2001:14b8:1801:c001::4 prefixlen 48
        inet6 2001:14b8:1801:c001::5 prefixlen 48
        inet6 2001:14b8:1801:c001::6 prefixlen 48
        inet6 2001:14b8:1801:c001::7 prefixlen 48
        inet6 2001:14b8:1801:c001::8 prefixlen 48
        inet6 2001:14b8:1801:c001::9 prefixlen 48
        inet6 2001:14b8:1801:c001::10 prefixlen 48
        inet 62.165.159.204 netmask 0xffffffff broadcast 62.165.159.204
        inet 62.165.159.205 netmask 0xffffffff broadcast 62.165.159.205
        inet6 2001:14b8:1801:c001::1 prefixlen 48
        inet 62.165.159.206 netmask 0xffffffff broadcast 62.165.159.206

::1 is "real" address and rest are aliases. All added with same command
like this:
ifconfig em0 inet6 2001:14b8:1801:c001::9/48 alias

But the funny part is. Couple of addresses do work and rest don't. ::1, ::2
and ::42 works. They can be used to connect irc and
they work fine as ping6 source. Rest behave like I said in first post.
