The problem with setting the URL to the ip address is that it messes with the visual look in the address bar. So, if we want reliable resolution and good looks we'd need to resolve each dnssd address (e.g. `foobar.local`) to their ip address (e.g. 172.17.0.1) via kdnssd and then resolve that back to a hostname via glibc/qhostinfo (e.g. `foobar.sky.net`). That way we'd know that the name we have in the end is in fact resolvable by the system without aid from dnssd. Speed impact of this aside it also adds 3 additional points of failure (and KDNSSD currently doesn't implement the resolver API it seems).
  
  
  I would recommend assuming DNS and systems are configured properly. I say that as someone with ~15 years IT experience. Modern IT networks are so heavily reliant on it (ever set up a VMware cluster? phew!), almost nothing works if it is not set up properly.
