As most of you know, putting a link into a post automatically makes it a link (e.g. http://localhost/) We can force the linkification with angle brackets (
<http://localhost/>) if the markdown somehow misses it. But (as far as I know) there's no way to force the address to not be made a link. Such a feature would be nice when we need example addresses, there's no reason to have a link to http://www.example.com/, for instance, or http://184.108.40.206/domain.com/, from the question where I thought of this.
I think an easy way to mark this up would be something like
<!http://example.com>, making the address appear in plain text without the hyperlink.
This came to my attention in this question: can't open transfered website from old DS to new DS
