Primary & Secondary DNS problem
Primary = ns1.nameserver.com , IP = xxx.xxx.xxx.x1
Second = ns2.nameserver.com , IP = xxx.xxx.xx.x2
Both name servers are located at different geographical locations (mentioned here because some are located in the same server)
Additional info : the secondary name server is a new name server that I just got and updated. Before this, the secondary name server is in the same server as the primary.
The SOA settings at the primary name server is :
@ IN SOA ns1.nameserver.com. server1.xxxx.com. (
2004030802 ; serial number
28800 ; refresh [1h]
7200 ; retry [10m]
3600000 ; expire [1d]
86400 ) ; min TTL [1h]
The SOA settings at the secondary name server is :
@ IN SOA ns2.nameserver.com. server2.***********. (
2004032302 ; serial number
14400 ; refresh [1h]
7200 ; retry [10m]
3600000 ; expire [1d]
86400 ) ; min TTL [1h]
Domain whois updated too as :
primary ns1.nameserver.com
secondary ns2.nameserver.com
After 24 hours of updating, even though the primary name server is still available, the domain is already resolve to its secondary name server and keep on pointing to the secondary instead of the primary. So all emails was sent from the secondary too !
Why is it behave like that ? Any thing wrong with the settings ?
Other than the SOA settings, anything else that may cause this problem ?
Appreciate any help.
