i Have 3 Server's in three diffrent Region, i want to Divert trafic by region. like American Trafic divert to american Server, African Trafic divert to African Server, already i'm Used This Service on Oracle Cloud, it's Very Costlly, so how do i do it , like this, After Create DNS Server.
Hi Dear I am facing one issue , tried to solve but not able to find solution. fresh bind install and just start the service. then disable dnssec but still facing the same issue.
Hi Paul tech support Can u help me i am done all the setup as per your guide lines now i just configure only forward zone setup but i am using dns for our lint it is working but i don't understand how to globalize this server .i assign a static ip in this server.
i have configured dns server, all configuration is ok but when using dig or nslookup for reverse/forward zones from client side it is throwing connection timeout no Server could be reached. help me out
Paul Technicals I again tried it works. Thank you But I have a doubt I was told some different configurations in zone file. It was In forward zone: @ IN NS FQDN first name of FQDN IN A IP address of DNS server In reverse zone: @ IN NS FQDN Last number of DNS server ip address IN PTR FQDN So I was confused. Is this configuration correct.

So I was confused.
Is this configuration correct.
sir i have a issue in status error is (network unreachable)how to troubleshoot sir
Check firewall settings, and restart network, also check your other servers which are connected with same network or not
But how ...bro....make video for this......it's too much needed.....
My dns server and postfix mail server is same I have not able to send the mail to other machine error is host or domain name not found name service error for = xyz type=AAAA : Host not found
You need to check your AAA entries and also mail server entries this is also important
Host name not found that means dns not working
Hello, from second virtual machine dig command fails.. Wht is the solution?
