I am having a headache with DNS.
Lets say my public IP is 1.2.3.4, my local IP is 192.168.0.10 and my domain is example.com
I am running CentOS on a virtual machine (Parallels Desktop for Mac) with a LAN card reserved for it, so it gets Ip directly from the router. I have ports 80,443,53 forwarded to 192.168.0.10. Both Mac OS and CentOs firewalls are Off.
The strange is when I type
dig @1.2.3.4 example.com from my other PC I get:
; <<>> DiG 9.8.3-P1 <<>> @1.2.3.4 example.com
; (1 server found)
;; global options: +cmd
;; Got answer:

but when i type: dig @ns1.example.com example.com it waits a few seconds and returns dig: couldn't get address for 'ns1.dsht.in': not found
