With difficulty
If you have extended tooltips enabled (more options) you can hover over the hosts column where it says "multiple" and see all the ip numbers. If you type one of these into direct connect you may be able to browse host. Repeat for all ip numbers
If you see the number elsewhere on the search page, you can try to browse host from there.
Chatting can only be done if you can browse the host first, or you see the ip number elswhere on the search page displaying a chat icon. Chat only works if you are very lucky btw, it is not atall reliable, and browsing host is by no means certain to work.
