4.7 IP alias ?

[Jacques Beigbeder]

I have a host with GENERIC 4.7 kernel:

# uname -a
FreeBSD federation 4.7-RELEASE FreeBSD 4.7-RELEASE #0: Wed Oct  9 15:08:34 GMT ...

I have an interface like:

# ifconfig fxp0
fxp0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
        inet x.y.z.16 netmask 0xffffff00 broadcast x.y.z.255
        inet6 fe80::2b0:d0ff:feea:7442%fxp0 prefixlen 64 scopeid 0x1 
        ether 00:b0:d0:ea:74:42
        media: Ethernet autoselect (10baseT/UTP)
        status: active

The other interface (fxp1) is unused.

Then I try to set an IP alias, same interface, same network, another
IP address, the end is .250 instead of .16.

# ifconfig fxp0 x.y.z.250 netmask 255.255.255.0 broadcast x.y.z.255 alias
ifconfig: ioctl (SIOCAIFADDR): File exists

Why does this command fails?
I'm used to use this on 3.4, 4.5...
