Sorry... DC = Direct Connect, its yet another peer-to-peer file transfer protocol/network....see wiki for info.
ISP's can shape the traffic by the protocol it uses... I think it also bands in with QoS, giving different protocols prioirty over others.
In this case its being used so that if DC traffic is being routed through the ISP, the ISP shapes the traffic down to 0kb/s which grinds the connection to a halt and ultimately times out.
What I'm after are any anecdotes from users of Wired Country who've come across protocols that seem to go nowhere.. as well as if someone has the quick answer to: Does Mirc use DC or another protocol that would likely be on Wired Country's 'black list'.... so to speak.
Or even if its simply a case of locking down certain ports.. or a combination of both.
Wired Country do no layer 3 or above traffic shaping. They wholesale the service to other ISPs in addition to their own internet service offerings, what third party ISPs do with traffic shaping from then onwards is that ISPs issue entirely.
