What are nameservers?
Computers communicate using numbers, called IP addresses, to contact each other, much like using a phone number to dial a specific person's phone. Domain names on the internet are much like entries in a phone book. The phone book tells people looking for a business what the entries are, just as a domain tells people (i.e., their computers) that a domain is hosted on the server.
This is why the Domain Name System (DNS) is a central part of the internet, providing a way to match names (a website you're seeking) to numbers (the address for the website). DNS syncs up domain names with IP addresses enabling humans to use memorable domain names while computers on the internet can use IP addresses behind the scenes.
In fewer words, nameservers define your domain's current DNS provider, and that is where your DNS is managed. Without the correct nameserver settings, your email and website won't work correctly.
Changing nameservers from Namecheap to HostArmada
Before you start with the DNS configuration, it is first vital to locate your HostArmada nameservers, which are found by logging into your client area and going under the “My Services” section.
Step 1. Sign in to your Namecheap account.
Step 2. Select "Domain List" from the left sidebar and click the Manage button next to your domain.
Step 3. Navigate through the domain list and locate the desired domain name. Once you find it, please click on the "Manage" button.
Step 4. Find the Nameservers section and select "Custom DNS" from the drop-down menu.
Step 5. You will need to fill in your HostArmada nameservers in the relevant fields, and after that, click on the green checkmark to save the changes.
Please be aware that nameservers changes do not propagate instantly. Once your nameservers are changed, it may take up to 24 hours (more, in rare cases) for local ISPs to update their DNS caches so that everyone can see your website.
You can always check your domain name using any Proxy server as Proxy servers do not store cache. Thus you can see the non-cached information.
