<p>I concur with Munroe. I maintain https://github.com/jsumners/ucarp-rhel7 for my HAProxy failover setup. My guess is that your opposition could stem from multiple OSes not supporting this sort of socket binding. Some quick searching shows me that at least
FreeBSD supports it via the “IP_BINDANY” options http://fxr.watson.org/fxr/ident?i=IP_BINDANY. On Linux it is is “IP_FREEBIND”. These are defined in
<code>netinet/in.h</code> and <code>netinet/ip.h</code>, respectively.</p>
<p>I think this would be a good feature to support since, as far as I can tell, routers don’t typically allow defining a backup “ip helper.”</p>

<div>Kea is like 99.99% of network servers I know: it binds only to local addresses
<br>
as required by the standard socket API. <br>

PS: I am sure you'll get the same problem with bind9 for instance. <br>
