The clue for you to answer this question about Secondary DNS is redundancy! If you run or own an online business, you understand very well how important it is to rely on additional resources, not a single one, to keep operating.
Let’s go deeper to answer this question properly.
What is Secondary DNS?
Secondary DNS is a service you can get to back up your Primary DNS. It is an alternative network of name servers used to save copies of the zone file and your domain’s DNS records. A Secondary DNS added to your Primary DNS will give different points of presence (PoPs) to your domain. And this represents many benefits for your online business.
When you get the Backup DNS, all its network servers will only save copies. This means it’s safe because it does not allow any addition, removal, or modification to your domain’s DNS records. Doing such actions is possible only on the Primary DNS.
If you look for Secondary DNS information or services, you will find it as Slave DNS or Backup DNS too.
Why is it crucial to invest in Secondary DNS?
It’s crucial to invest in it because it provides redundancy, improves DNS resolution, and offers extra benefits to your online business.
Adding the service of Secondary DNS will be easy for you. Its configuration takes only a little time. A Secondary zone must be created, and a zone transfer executed to copy the Primary DNS zone file on it. The frequency for the Secondary servers to get an updated copy of the DNS data can be set up from the beginning on the Primary DNS. Later on, they will do this task automatically.
Redundancy for your online business.
When you get Secondary DNS, you are getting not another server but many more servers globally distributed to your network. This is a huge benefit because no matter where on the planet your clients request your domain, they will receive an answer. Visits to your website won’t be interrupted due to failures, attacks, or downtime on a server. This is the level of redundancy you need to solve downtime issues. If a server is down, another will for sure work!
Reliable DNS backup.
To have a reliable copy of the DNS records of your business and the zone file itself on the Backup servers is not bad at all. If something goes wrong with your Primary DNS, you will have copies of these important DNS data.
Improvement of the overall performance.
Having such an extra network working together with your Primary DNS will produce a positive domino effect. The speed to resolve DNS requests will be quicker. Latency won’t be a problem. Clients will load your domain faster. This effectiveness in handling the traffic will prevent stress on your Primary DNS.
Having a Secondary DNS is a crucial investment! You should not miss all the benefits it can provide to your daily online operation. If you still don’t have it, consider the investment seriously!
