This is the source of the problem. The indexes for this table are
ipAddressAddrType and ipAddressAddr. That means that an ipAddress on
multiple interfaces will not have a unique index.

So, to deal with this, you would have to add support for the ipv4z InetAddress
type. This adds an extra 2 bytes to an ipv4 InetAddress, for the 'zone.' Then
you would have to make sure that the zone portion is consistently set to the
same value.

I haven't checked, but this might (probably will) require updates throughout
the code to deal with an ip address that is not 4 bytes long.

You could change the code so that the container is only loaded when required to
satisfy a request. This means that the ipAddressLastChanged object won't be
reliable in any sense of the word. I'm not sure how this might affect the
if*Table modules either...
