Description

When you change the IP of an interface (ex: LAN) using the Interfaces > [name] page, the old IP remains on the interface.

For example, changing the LAN IP from 192.168.1.1 to 192.168.10.1, upon applying the settings, ifconfig shows both IPs on the interface:

em1: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500
        options=9b<RXCSUM,TXCSUM,VLAN_MTU,VLAN_HWTAGGING,VLAN_HWCSUM>
        ether 00:0c:29:41:01:67
        inet 192.168.1.1 netmask 0xffffff00 broadcast 192.168.1.255
        inet6 fe80::20c:29ff:fe41:167%em1 prefixlen 64 scopeid 0x2 
        inet 192.168.10.1 netmask 0xffffff00 broadcast 192.168.10.255
        nd6 options=3<PERFORMNUD,ACCEPT_RTADV>
        media: Ethernet autoselect (1000baseT <full-duplex>)
        status: active

Side effect of this bug is being unable to change DHCP settings on LAN after applying, but that's really a separate issue I'll start another ticket for.

The expected behavior would be for the old IP to be removed, and only the new IP to be present.
