I strongly support this because callers often come to our chat using different aliases. At present we have to open each message individually to search possible aliases with a common IP address.

Yes, I could really use this right now where we are getting some harassing individuals on our chat. After a few times now we want to gather evidence regarding the issue but cannot because there is no IP search. :(

It would great if you provide search option with ip address, in most of the case if a customer comes again, its not reflecting in the history, so this option will be moreful to search the old chats.
