562	Source and destination address selection	Jiri Svoboda	Jiri Svoboda	"If you try to connect to or ping a host that has an AAAA DNS record (e.g. google.com), we will always try to use that regardless whether there is any (global-scope) IPv6 address configured. Thus on a host with only IPv4 connectivity this will fail.

There are cases where we are faced with several alternatives for both source and destination address, such as:

 * IPv4 vs IPv6
 * link-local vs. global-scope address (both IPv4 and IPv6)

We need to devise some strategy for proper selection of source and destination address. For inspiration how this problem can be approached see

 * http://tools.ietf.org/html/rfc3484

(I don't think it's necessary to implement *exactly* this way, i.e. we don't necessarily need a configurable policy table)."	enhancement	accepted	major		helenos/unspecified	mainline
