Linode DNS Manager - SOA Serial in Zone file generated text
At the end of my updating session, I decided to click on the "Zone file" link for each of my domains in the DNS Manager's web interface and copy and paste the resulting text to notepad. I put the serial number in the file name and saved the text to files on my home computer.
Later today (about 4 hours) I was reviewing the notepad files and then looking at the DNS Manager's web interface and noticed that the serial number was different (incremented, went from …2062 to …2077) even though I hadn't made any changes since my last session at 12:30PM.
(1) Is this serial number incremented every 15 minutes regardless of any customer changes?
(2) Or is this just something the web application does in generating the zone file text and can be ignored?
Hope that helps,
@caker I suspected as much as I looked at my SOA records via dig throughout the day and found that they remained at the 2061/2062 serial numbers based on the last update.
Thanks for the replies.
