The use case is general-use IRC clients looking to distinguish twitch chat from other IRC networks for purposes of the client handling twitch differently.
To explain better. I’m looking for a way to tell if a user-input string is a twitch-chat server. For host names its easy to check the text against irc.twitch.tv and tmi.twitch.tv. But what if the user inputs an ip address, say to connect to a specific chat server such as the group-chat servers? Is there a way to determine if said specified IP address is a twitch chat/tmi server.
