What Is DNS?
Updated 4 weeks ago
DNS (Domain Name System) is the system that tells each domain which server to look to for its website content: the files, email, and databases hosted on a web server. When someone enters your domain in their browser, DNS directs the request to the right place.
DNS Delegation and Servers
Delegating a domain means specifying which DNS servers are responsible for it. You choose these servers when you register the domain, and from then on, they store its records.
If you host your site with us, you delegate the domain to our DNS servers:
mar.ns.duplika.com
nic.ns.duplika.com
emi.ns.duplika.com
rei.ns.duplika.com
With a reseller plan, you can use our anonymous DNS servers (ns1.servidoronline.net and ns2.servidoronline.net) by contacting us to have them configured on your account. On a VPS or dedicated server, we can help you configure your own DNS servers. You can find the complete list and their IP addresses in the Duplika DNS guide.
DNS Records
DNS records are the domain's address book: each entry points to a location, usually using IP addresses. Each record type serves a different purpose, and they are not interchangeable.
Type | Purpose |
|---|---|
A | Point a name to a server using IPv4. |
CNAME | Make a name an alias for another. |
MX | Specify which servers receive the domain's email. |
TXT | Publish a verification or information such as SPF, DKIM, or DMARC. |
Where to Edit Records
When your domain uses our DNS servers, you can edit its records in cPanel under Zone Editor in the Domains menu. There, you can view the address book and create or modify your domain's records.
We recommend editing records only if you understand the change you're going to make. If you're unsure, contact us and we'll guide you through the process.
For step-by-step instructions on creating or modifying records, follow the guide How to Create and Edit A, CNAME, MX, and TXT Records in cPanel.
How Long It Takes for a Change to Appear
After you edit a record or change the delegation, the change may appear within minutes or take several hours; in some cases, it can take 48 to 72 hours or longer. What we call propagation is the updating of DNS caches across different providers, and you don't need to wait that long before you start checking for the change. To check it, follow the DNS propagation guide.

If you need to point your domain to Duplika, the steps depend on where it's registered: you can delegate a .com.ar domain or change the DNS settings in GoDaddy. If the domain is already delegated to our servers and you need to add it to your hosting account, follow the guide to add an addon domain or subdomain.
