What is the issue you’re encountering

Don’t understand how to add an SOA record

What steps have you taken to resolve the issue?

Looking at pixata.co.uk Domain Health, I see a warning “SOA Serial Number Format is Invalid” and would like to fix it. It seems I need to add an SOA record, but cannot find out how to do this.

I have searched around, including a Cloudflare article on the subject (https://www.cloudflare.com/en-gb/learning/dns/dns-records/dns-soa-record/) but am no wiser.

Anyone able to advise?

What feature, service or problem is this related to?

Just ignore that, there is no such thing as a valid serial number format. Also, you can’t do anything to change it.

@Laudian Thanks for the reply.

Bit surprised, as if there is no such thing, why is mxtoolbox warning about it?

Thanks again

That’s a very good question that I don’t have an answer to.

Most SOAs use a timestamp for the serial number, but there is no rule that you have to.

I saw the same warning on my site. You can’t manually add or change SOA records if you’re using a managed DNS provider like Cloudflare — they handle it automatically. The “SOA Serial Number Format is Invalid” warning can safely be ignored.
