[OT] How to find out who to contact with Internet network problems?

["Ralf G. R. Bergs" <rabe@RWTH-Aachen.DE>]

Hi there,

this is probably an off-topic question to this list. Sorry for this, but I 
don't know who else to ask or where to look, therefore I hope that my 
question is read by an experienced network admin of a large company network 
or an otherwise experienced user who can answer my question.

Ok, I'm trying to contact a host across the Internet. The connection is very 
bad, packets get lost with a percentage of up to 30%. I traced the route and 
found the point where trouble is probably caused.

If I ping a certain host/router (let's call it B), LOTS of packets get lost. 
If I ping the router one hop nearer to me (named A) only a small, negligible 
percentage gets lost.

Who do I contact? The admin of A or B? How do I find out who is responsible? 
Is it ok to use the tech-c that I look up using whois?

Thanks,

Ralf
