It is Turkish Cable Net (actually same with Turk Telekom anyway),
i doubt i can get any answer from them, their support is utter crap. really! Here is possible conversation:
Me: Cant lookup my ip address from anyhwere. What can be reason the reason?
Tech person of Turk Telekom: Can you please reset your modem and your router?
Me: OK, Never mind (hang up the phone).
