H allows IRC4Fun users to mask their host with a vHost 
 that can be activated.
 
 When applying for a vHost; you should request the vHost in 
 the form of: MyNick.users.IRC4Fun.net as this is the 
 only vHost currently being approved.
 
 
 * Users cannot request vHosts that contain real domain names 
 that do not belong to them.  In order to prevent DDoS attacks 
 towards innocent domains; You should request something like: 
 myNick.users.IRC4Fun.net.  No other vHosts will be approved
 at this time.

 Syntax: /msg H  ON

 When you use this command any user who performs a /whois
 on you will see the vhost instead of your real IP address.

 Syntax: /msg H  REQUEST <vHost>

 Syntax: /msg H  SET <nick> <hostmask>.

 well as vhosts.

 Syntax: /msg H  SETALL <nick> <hostmask>.

 Sets the vhost for all nicks in the same group as that
