The most popular DNS server software — it answers questions like 'what IP address is this domain using?'
Why it matters
Who controls DNS controls traffic to the domain — including email and certificates.
What's missing without it
Without a properly configured zone, the domain disappears entirely from the internet. A forgotten serial number is the most common cause of 'I changed it, but nothing happened'.
When it is used
When transferring domains, configuring email, setting up subdomains.
How we use it
Zone described in a text file; after every change, the serial number must be incremented, otherwise secondary servers won't pull the update.
Numbers worth knowing
