Hi! I'm trying to figure out the way DNS works. I've follow some of the DNS guides here at HowtoForge, but i'm not really sure if i'm moving forward or if i still have issues. I've created the DNS Zone for the purchased domain, mydomain.com There on the records i've created ns1 and ns2, A records pointing to the server IP(v4). Code: Active Type Name Data Priority TTL * A mail 220.127.116.11 0 3600 * A ns1 18.104.22.168 0 86400 * A ns2 22.214.171.124 0 86400 * A mydomain.com. 126.96.36.199 0 3600 * A www 188.8.131.52 0 3600 * MX mydomain.com. mail.mydomain.com. 10 3600 * NS mydomain.com. ns1.mydomain.com. 0 3600 * NS mydomain.com. ns2.mydomain.com. 0 3600 I've setup those as name servers from my dynadot control panel, AFAIK glue records for dynadot are name servers with a defined IP. Then use both ns1.mydomain.com and ns2.mydomain.com and dynadot say: "Your domain is using your hosting provider's name servers. All website settings and email services are configured through them." At this point i thought that i only needed to wait up to 24 hours but i'm around that mark and i see no change at all, then tried to ping BIND. Logged into my server and did, Code: dig @localhost mydomain.com ; <<>> DiG 9.9.5-3ubuntu0.7-Ubuntu <<>> @localhost mydomain.com ; (2 servers found) ;; global options: +cmd ;; Got answer: ;; ->>HEADER<<- opcode: QUERY, status: SERVFAIL, id: 45480 ;; flags: qr rd ra; QUERY: 1, ANSWER: 0, AUTHORITY: 0, ADDITIONAL: 1 ;; OPT PSEUDOSECTION: ; EDNS: version: 0, flags:; udp: 4096 ;; QUESTION SECTION: ;mydomain.com.
