(I'm getting a DNS error?)
- aaron-lebo 14y agoStrange. I've had users sign-up, I've had someone say it works on the Google DNS, but you aren't the first with DNS errors. I'm hosting it on gandi's DNS, I wonder what I'm not doing right.
- bdash 14y agoI think this is because an A record query for www.kodefund.com returns multiple CNAME records, which is not compliant with the DNS specification: mrowe@vega:~$ dig A www.kodefund.com @a.dns.gandi.net ; <<>> DiG 9.8.1-P1 <<>> A www.kodefund.com @a.dns.gandi.net ;; global options: +cmd ;; Got answer: ;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 53562 ;; flags: qr aa rd; QUERY: 1, ANSWER: 2, AUTHORITY: 0, ADDITIONAL: 0 ;; WARNING: recursion requested but not available ;; QUESTION SECTION: ;www.kodefund.com.
