Comment 1 for bug 405786

Exclusive role should always have only one ip. mmm should check this and die if more than one is configured.
We should introduce ip "aliases" for cases where multiple ips (one per subnet) must be configured. config syntax could be something like this:
<role writer>
    hosts db1, db2
    ips 192.168.0.50
    mode exclusive
</role>

<ip 192.168.0.50>
    alias 192.168.1.50, 192.168.2.50, 192.168.3.50, 192.168.4.50
</ip>
