I am having some very bizzare DNS issues and am wondering if anyone
will be able to shed some light on this. A customer of ours started
recieving thousands of DNS requests for a wide range of domains,
mostly foreign. The requests are coming from a wide range of ips
most of which respond to nslookups "ie are nameservers". I have done
a whois on some of the domains and the 2 name servers having the
problems don't show up, I have also check to root servers and dont see
anything which would direct those domains to the name servers. Their
entire T1 is full from these requests about 1.2 meg. As the customer
is in the business of web hosting they can kill named nor can they
put up a packet filter to fix this. Also because there are literally
hundreds of diffrent domains both preforming the lookups and being
looked up it is not feasable to call the admin of each one to work
this out. Anyone have any ideas?
