I host my dns on fedora, im using WEbmin
I go to Bind DNS, and edit my Master Zone, All address
and modify my mailserver (our mail hoster changed our email server)
previously was mail.xxx.com , 110.x.x.156 change to x.159.
After I changed it, I apply and even stop and start nameserver again...
and even init 6 the server..
Still some of the pc still when i ping mail.xxx.com it returns x.156.
I did a ipconfig /flushdns or client, reboot, renew ip..
Still the same..
What else can do i ?
