Still seeing these same questions over and over. DALNET is dogshit man!
It's NOT Invision. Most of the Dalnet servers are down most of the time. They are being attacked by goofy little dweebs with nothing better to do, and aparently the Dalnet administrators either don't care, or can't find anyone with the brain enough to track these attacks. It's been going on since August or September. You'll get wierd notices, "can't connect to assigned address" etc., or it'll just time out. Dalnet usually goes down for an entire weekend at a time.
Again, this is NOT an Invision problem...you can't connect to a network that is not there...
Hope this helps clear this up.
