There's nothing fishy about that, just two addresses in the same subnet. I've been using this myself since many years (though with the old eth0:x alias method) to run multiple services on one server and leave me the option to move some of them to another server without caring about DNS caching. I call it the "1 address per service" model. I didn't test it, but changing the netmask of the second IP address to /32 could prevent it from reaching the default gateway. It's not necessary anyway. -- ## List details at http://www.exim.org/mailman/listinfo/exim-users ## Exim details at http://www.exim.org/ ## Please use the Wiki with this list - http://www.exim.org/eximwiki/
