You can certainly do that. However, that's baking into your code both
ports and addresses, which means that should you need to migrate your
cluster/ha-setup elsewhere, you'll have to recompile your clients. Thus
it might be better to us something like ha-proxy, or maybe just
DNS (round-robin or not) with a very short TTL will suffice. There are
many ways to skin this particular Rabbit...
