What do you think is a remote DNS query?

How should this work? With ssh you can connect to remote ssh-server and
nothing else. You might want to use dynamic forwarding:

ssh -D 8080 MySSHServer.some.where

and then tell your browser to use the socks-proxy localhost:8080

But when you type http://some-host.net/abc.html into your webbrowser,
how does this browser translate it to a valid tcp-adress? This is not a
problem of ssh but of your webbrowser. There are browsers which can be
configured to do remote DNS query. As far as i know, using the local
DNS-server is standard behaviour of most programs -not ony webbrowsers
but also newsreaders, emailprograms, chatprograms. Have a look at the
about:config page of your browser and understand the manual before
changing anything.
