How to disable ProxyCommand for one particular host?

Question

Using OpenSSH, I have set my /etc/ssh/ssh_config to have a ProxyCommand so all SSH connections go through that proxy.

/etc/ssh/ssh_config:

Host *
  ProxyCommand nc -X connect -x localhost:8111 %h %p

But I would like to disable the proxy for one particular SSH host.

I have added the following to my ~/.ssh/config:

Host ssh.example.org
  HostName ssh.example.org
  ProxyCommand ""

What should I put with ProxyCommand so that it doesn't use a proxy for that particular host only, but the default is still to go through the proxy for SSH conncetions?

The solution is to use ProxyCommand none for hosts that should go outside the proxy!

Host ssh.example.org
  HostName ssh.example.org
  ProxyCommand none

Adding the lines below in: ~/.ssh/config works for me on Ubuntu. Note that there is also ability to exclude multiple hosts/ips from the proxy setting and also the HostName is not needed:

Host localhost 192.168.1.10 192.168.1.11
  ProxyCommand none

Host *
  ProxyCommand /usr/bin/nc -X 5 -x localhost:8111 %h %p
