- A DNS zone is any distinct, contiguous portion of the domain name space in the Domain Name System (DNS) for which administrative responsibility has been delegated to a single manager. The domain name space of the Internet is organized into a hierarchical layout of subdomains below the DNS root domain.
Most top-level domain name registry operators offer their name spaces to the public or to entities with mandated geographic or otherwise scoped purpose for registration of second-level domains. Similarly an organization in charge of a lower level domain may operate its name space similarly and subdivide its space.
Each registration or allocation of subdomain space obligates the registrant to maintain an administrative and technical infrastructure to manage the responsibility for its zone, including sub-delegation to lower-level domains. Each delegation confers essentially unrestricted technical autonomy over the allocated space. An area of one or more subdomains that has been delegated for management is called a DNS zone. A zone always starts at a domain boundary to include all leaf nodes (hosts) in the domain, or it ends at the boundary of another independently managed zone.
As each domain is further divided into sub-domains, each becoming a DNS zone itself with its own set of administrators and DNS servers, the tree grows with the largest number of leaf nodes at the bottom. At this lowest level, in the end-nodes or leaves of the tree, the term DNS zone becomes essentially synonymous with the term "domain", both in terms of use and administration. The term domain is used in the business functions of the entity assigned to it and the term zone is usually used for configuration of DNS services.

you explained this better in 13 minutes then my prof in 1 semester, i wish every prof was just like you. Thank you for this!
You Sir are Credit to the Subject of DNS-Zones. You truly made it a pleasure to watch your Video in simple layman's and Real world scenario examples. IT Doesn't Have to be Difficult !
- Thank You.
The best explanation that I've found !!! Great job!
Great vidoe but the music is killing me.
Neat. You don't even need a Server to grasp it; from this, I got pretty much all my unanswered DNS questions. Thank you
Simple and clearly explained, thank you for that!
Admittedly, at the end of the video I asked myself where this is all going until I watched another one of the videos in your channel "Routing IP". This all came together. Possibly a good idea to recommend the 'next' video at the bottom of the video's description box, which can be edited at any time. I understand that videos are put together at different times and sometimes, as you go by demand. This is just a side note, not a complaint. Again, thank you for such nicely organized and well presented video.

Explained very well with an example, yet difference between primary and secondary zones are not mentioned. I was actually expecting to see it here in this example. Or is it explained implicitly?
TH-camrs are the greatest teachers!!! Hate of to you sir :)
I liked this tut. it was in layman langauge so easy to understand what is DNZ zone all about
Thank you so much :P the best explanation on dns zone I've ever had
Tks for detail explanation, just study DNS related knowledge and it's helpful. !
terrific - proves my instance that training should begin with something concrete - like a real-world example - before introducing the abstractions
Maybe no BGM in the future
Off topic but could you provide me with a link or name to the background music? Thanks. Very helpful video btw!
Awesome! Thank you for this video, super useful
Huge Huge Huge respect for background music, mate! Been looking something like this for years. Just hell accelerates studying. Subscribing !

Thanks so much for the video the explanation is excellent would love to learn more from you please let me know how to contact you may be a email etc
Simple and so easy to understand! Thanks a lot. The only issue for me is what exactly all those departments (zones) relate to: websites, IP addresses? I´m an absolute beginner. Also some people complained about the music... But I loved it. Background, low and relaxing sound, it put me in the learning mood.
Such a great explanation and a very relatable example, helped a lot in understanding the concept. as they say examples are better then percept.
Watch the original video, without the music!
