Comment:
This is a core tor feature request.
It could be implemented by extending ReachableAddresses to resolve DNS
names when parsing the policy.
But there are a few issues with this:
* DNS resultion results change, we would have to periodically refresh the
policy;
* do we do this based on record TTL?
* what if DNS fails? temporarily? permanently?
* this has caused us other issues in the past
* DNS names can resolve to multiple IP addresses depending on time and
location and various other factors, how can we know we have them all?
* tor tries very hard not to depend on DNS because it can be a weak link -
it's not authenticated,
* leaking the sites users are prepared to access via DNS queries could
identify the user, or make those sites the target of attacks.
