Note that which side the address is resolved on is under the control
of the SOCKS client. eg, in firefox this is about:config
network.proxy.socks_remote_dns.

The up side is that the client can implement different retry
behaviour.  The down side is that any addrress resolution on the
client side leaks information.

usually comes from bad judgement.
