DNS Serial number issue

Hi all,

I have a pair of Virtualmin servers set up to host my DNS, once as master the other as slave, When I use DNS Check on MxToolbox, I always get the following message for the domain:

ns1.xxxxxxxxxx.com reported Serial 1374243228 : Suggested serial format year was 1374 which is before 1970.

Is this something to worry about, or can I just ignore it?

Thanks in advance!

Some scripts will report a problem with SOA if is not in proper format e.g. from left to right:

YYYYMMDDSS

Y - year

M - month

D - day

S - sequence number

For example if i would set DNS server today my SOA number would be 2016100201. Every time there is a change in DNS sequence number will go up by one:

2016100201

2016100202

2016100203 ....

I would suggest to properly set your SOA: https://www.ripe.net/publications/docs/ripe-203
