MYDOMAIN.COM faking auth on COM.BR zone
Dear Nanog Readers, As we have not yet received any response from our abuse request (attached) to MYDOMAIN.COM and more 10 phone calls we are looking for help of any kind here. COM.BR zone is populated with 280K zone delegations (92% of the .BR registered domain names). Mydomain.com DNS servers are delegated to 1361 domains inside the .BR zone. We don't known why but these servers are answering authoritatively to COM.BR zone and they are carrying a wild card record to. This is causing some confusion and trouble to buggy resolvers (notably NT). If someone knows a contact different of the whois and the web site information please let me known asap privately. Best Regards Frederico Neves .BR tech contact --begin bash> dig @a.root-servers.net br ns ; <<>> DiG 8.2 <<>> @a.root-servers.net br ns ; (1 server found) ;; res options: init recurs defnam dnsrch ;; got answer: ;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 6 ;; flags: qr rd; QUERY: 1, ANSWER: 5, AUTHORITY: 0, ADDITIONAL: 5 ;; QUERY SECTION: ;; br, type = NS, class = IN ;; ANSWER SECTION: br. 2D IN NS NS.DNS.br. br. 2D IN NS NS1.DNS.br. br. 2D IN NS NS2.DNS.br. br. 2D IN NS NS3.NIC.FR. br. 2D IN NS NS-EXT.VIX.COM. ;; ADDITIONAL SECTION: NS.DNS.br. 2D IN A 143.108.23.2 NS1.DNS.br. 2D IN A 200.255.253.234 NS2.DNS.br. 2D IN A 200.19.119.99 NS3.NIC.FR. 2D IN A 192.134.0.49 NS-EXT.VIX.COM. 2D IN A 204.152.184.64 ;; Total query time: 768 msec ;; FROM: clone.registro.br to SERVER: a.root-servers.net 198.41.0.4 ;; WHEN: Fri Sep 1 17:52:07 2000 ;; MSG SIZE sent: 20 rcvd: 209 bash> dig @NS.DNS.br. com.br ns ; <<>> DiG 8.2 <<>> @NS.DNS.br. com.br ns ; (1 server found) ;; res options: init recurs defnam dnsrch ;; got answer: ;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 6 ;; flags: qr aa rd; QUERY: 1, ANSWER: 4, AUTHORITY: 0, ADDITIONAL: 3 ;; QUERY SECTION: ;; com.br, type = NS, class = IN ;; ANSWER SECTION: com.br. 1D IN NS NS2.DNS.br. com.br. 1D IN NS NS-EXT.VIX.COM. com.br. 1D IN NS NS.DNS.br. com.br. 1D IN NS NS1.DNS.br. ;; ADDITIONAL SECTION: NS2.DNS.br. 1D IN A 200.19.119.99 NS.DNS.br. 1D IN A 143.108.23.2 NS1.DNS.br. 1D IN A 200.255.253.234 ;; Total query time: 1 msec ;; FROM: clone.registro.br to SERVER: NS.DNS.br. 143.108.23.2 ;; WHEN: Fri Sep 1 17:52:24 2000 ;; MSG SIZE sent: 24 rcvd: 157 bash> dig @ns1.mydomain.com com.br any ; <<>> DiG 8.2 <<>> @ns1.mydomain.com com.br any ; (1 server found) ;; res options: init recurs defnam dnsrch ;; got answer: ;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 6 ;; flags: qr aa rd; QUERY: 1, ANSWER: 9, AUTHORITY: 0, ADDITIONAL: 7 ;; QUERY SECTION: ;; com.br, type = ANY, class = IN ;; ANSWER SECTION: com.br. 42m40s IN SOA ns1.mydomain.com. hostmaster.com.br.
