I have not been on in a while but I just connected to it no problems.
I am using revconnect, a variation of dc++
go to file - quick connect - then type interpool.dnsalias.com - then click OK
As long as you meet the requirements you are in.
I am not sure of the qualifications other than being connected to 3 hubs or less. There might be a min share size and min number of slots.
I got in with 4 gig share, 2 slots, in active mode, unregistered...
