It reduces the DNS server’s traffic by saving the queries locally, therefore it improves the performance and efficiency of the DNS server. If you got results something like above, then primary DNS server is up and is working perfectly! We need secondary DNS server, because in case of any problem with Primary DNS, then secondary dns server will still resolve quries.To configure Caching name server, edit /etc/bind/options file: Here, for.is the forward zone file. And 192.168.1.202 is the IP address of secondary DNS server. pri IN A 192.168.1.200 sec IN A 192.168.1.201 client IN A 192.168.1.202 200 IN PTR pri. First, Update server using commands: Save and close the file.I try to register DNS on these computer using ipconfig /registerdns.I check DNS on the server about an hour later and there is still no record showing up.
