you can also use ctrl+R

You'd be surprised how little some people know about bash ctrl commands.

generalize to gnu/linux tools.

I bind this to up-arrow in my .inputrc:

  "\e[A": history-search-backward
  "\e[B": history-search-forward

OP's method would be helpful when the line differs syntactically prior to the hostname e.g. different options, arguments, a pipe into it. Though that case is rare in my own usage.

Two more places to extract hostnames for ssh auto completion are .ssh/known_hosts and the .ssh/config.

Or give zsh a try, simply autoload compinit and it will do ssh/sftp auto completions along with a boatload more out of the box.

Ian MacDonald's bash completions (http://www.caliban.org/bash/) do this with known_hosts.

I usually set up my SSH autocompletes to read from known_hosts. The problem is that on some systems, like say Debian, the hostnames are hashed for security reasons. So you have to add the following line to your .ssh/config to get the hostnames back into a readable form.
