What is a DNS Zone?
Today, we’ll go over the building blocks of the DNS landscape: What is a DNS zone?
A DNS zone is a controlled space where you manage all DNS records for a domain. Keep reading to learn more.
DNS Zone Basics
First, let’s talk about what is NOT a DNS zone:
- A domain name or a single DNS server.
- Similar to a time zone.
- An implied physical separation.
DNS zones are used for control over different parts of the domain namespace. They are the separate spaces to individually manage your domain names. A zone allows you to personally manage your DNS records for the assigned domain and contains all of your domain’s DNS Records.
Zones delegate authority over the DNS for a domain. A DNS zone can contain multiple subdomains, and multiple zones can exist on the same server. Then, records can be created and managed within that zone.
For example: If you have a zone for example.com the zone will allow you to add records for that domain that the rest of the internet can see like sub.example.com. Sub.example.com can also be in it’s own zone if desired. DNS zones are not necessarily physically separated from one another, zones are strictly used for delegating control.
How Does it Work?
In our “What is a Domain?” blog, we mention that DNS is like a phonebook for the internet. In that case, the content or zone file in the DNS zone are entries in that phonebook and when people try to connect to a site it checks the phone book to see where that website is.
Not only that, but it helps make management more efficient and helps alleviate the workloads of multiple name servers. This allows for failover and load balancing. Domains are delegated to nameservers in which the zone, or zone file, is actually held.
