Or maybe DNS parameters should have their own "DNS" setting as:

 dns.servers
 dns.domains
 dns.options
 dns.priority
 dns.is-default

The old properties would be copied to the new setting when the connection is normalized, to provide backwards compatibility.

An "IP" setting would instead make sense if there are other protocol-agnostic IP properties we plan to add (but I can't imagine which ones now).
