What does Secondary DNS mean?

Using the Secondary DNS to preserve a trustworthy copy of your data is an excellent idea. We’ll look at why and how in this article. But first, let’s learn about what the Domain Name System is for.

Domain Name System (DNS): What does it mean?

DNS is a naming database system that locates and converts Internet domain names into IP addresses. Consider it like a directory or, more recently, your phone’s contacts list, where names and phone numbers are correctly matched.

The DNS directory is distributed globally and operates daily, assisting in searching and reaching millions of existing domain names.

Secondary DNS explanation

Secondary DNS is a service that you can use in addition to your Primary DNS. It provides an additional network of name servers for keeping copies of the zone file containing your domain’s DNS records. These servers can duplicate the Primary DNS zone file for your domain and give additional points of presence (PoPs). Users will be able to resolve your domain much faster this way, even if your Primary DNS is unavailable! Isn’t it fantastic?

Backup DNS or Slave DNS are other names for the Secondary DNS service. It’s also important to note that because it just saves copies, it doesn’t allow modifications to DNS records. You can only make changes to your Primary DNS.

Why is Secondary DNS advantageous?

There are four fundamental reasons to set up a backup DNS server:

  1. You will enjoy complete uptime. Users will be able to access your website using the backup DNS even if the Primary DNS goes down. If you’re in the e-commerce industry, you understand how critical uptime is to your bottom line.
  2. Make sure you have a solid backup plan in place. This is a wonderful backup option if something goes wrong with the Primary DNS. Backup DNS will duplicate your DNS records for you.
  3. Check to see that your Primary DNS server isn’t overburdened. You will be able to distribute the load and assure the availability of DNS records if a large number of inquiries are received.
  4. In the case of failure, malfunction, or attack, the sheer existence of a Primary DNS server carries danger. The authoritative records for the DNS zone will simply be unavailable. Secondary DNS is a fantastic approach to avoid dealing with this issue.

Conclusion

You now understand why Secondary DNS is critical for you and your company. These benefits are not only for being read but also for being experienced. Using Secondary DNS to protect your domain is a good idea. Make sure nothing is preventing your DNS from resolving. There will be no sales lost if you have 100 percent availability. So go ahead and do it!
