Hi, I am unable to resolve DNS records via nscache.ap.sixxs.net, but can ping it via IPv6. I am able to resolve records via other IPv6 nameservers. I am attempting to access this resolver via tunnel T42497 (handle SGC7-SIXXS) on POP nzwlg01. steve@neith ~ $ dig aaaa google.com @nscache.ap.sixxs.net ; <<>> DiG 9.7.3 <<>> aaaa google.com @nscache.ap.sixxs.net ;; global options: +cmd ;; connection timed out; no servers could be reached steve@neith ~ $ dig aaaa google.com @nscache.eu.sixxs.net ; <<>> DiG 9.7.3 <<>> aaaa google.com @nscache.eu.sixxs.net ;; global options: +cmd ;; Got answer: ;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 28304 ;; flags: qr rd ra; QUERY: 1, ANSWER: 1, AUTHORITY: 0, ADDITIONAL: 0 ;; QUESTION SECTION: ;google.com.
