I’ve been logging sip registrations from this IP address for 2 days now. I’ve
emailed the domain’s admin, but nothing seems to come of it.

I’ve routed him into oblivion, but still, I think 50 requests a second for 2
days is a bit much.

Any ideas?

  • I did send them an email at that address. No response.

    I tried the chat as well with no effect. My German is a bit rusty, or I’d call
    them….

  • You could traceroute the IP and contact NOC’s along the route. They might
    be interested to hear of flooding/DOS attacks being routed via their
    equipment.

    Well, I sended them email on 17/02/2012, no answer. I tried to call
    them, “schöne Musik (cool song)” but that’s all.

    Send them again an email in German with info that a discussion is going
    on on this list. Perhaps …
