Can Two Websites Have the Same Domain Name? Here's How It Works
Have you ever visited two websites with almost identical names but different content? For example, one business might use tokokita.id, while another uses tokokita.com.
This raises an interesting question: can two websites actually have the same domain name?
The short answer is two separate parties cannot simultaneously register the exact same fully qualified domain name within the same public DNS namespace. However, websites can use similar names, different domain extensions, or even share a domain through specific technical configurations.
Let's explore how domain names work and why uniqueness matters.
Why Must Domain Names Be Unique?
A domain name is an address that helps people locate websites and other services on the internet.
The Domain Name System (DNS) connects domain names to technical information, such as server IP addresses.
For this system to work consistently, domain names must occupy unique positions within the DNS hierarchy.
For example, if tokokita.id is already registered, another person cannot independently register the exact same tokokita.id while that registration remains active.
This principle helps prevent conflicts in domain registration and management.
Can Websites Use the Same Name with Different Extensions?
Yes.
Domain names with different extensions are considered different full domain names.
For example:
tokokita.idtokokita.comtokokita.nettokokita.co.id
Each is a distinct address and may have a different registrant, provided the applicable registration requirements are met.
This is why similar business names sometimes appear under different domain extensions.
However, registering a similar name under another extension does not automatically eliminate trademark or intellectual property concerns.
Can Two Websites Share One Domain?
Technically, yes.
A single domain can support multiple websites or applications through different configurations.
For example, a company might use tokokita.id for its main website, blog.tokokita.id for articles, and shop.tokokita.id for its online store.
These addresses share the same parent domain but have distinct hostnames because they use different subdomains.
Alternatively, multiple applications can operate under different URL paths, such as tokokita.id/blog and tokokita.id/shop.
With the appropriate server configuration, those sections may even be powered by separate systems.
Therefore, one domain can support multiple websites without being independently registered by multiple owners.
What Is the Difference Between a Domain and a Subdomain?
A registered domain name is obtained through an accredited registrar under the applicable domain extension's rules.
A subdomain is an additional name created beneath an existing domain, typically managed by whoever controls the parent domain.
For example:
Main domain: tokokita.id
Subdomain: blog.tokokita.id
Another subdomain: event.tokokita.id
Subdomains allow organizations to separate services without registering a new parent domain for every website.
However, DNS, hosting, and security settings must still be configured properly.
What If Your Preferred Domain Name Is Already Taken?
If your preferred domain is already registered, you cannot simply register the exact same name again.
However, several alternatives may be available.
You can consider another suitable domain extension, such as .id or .co.id, or add a relevant word related to your business, location, or service.
You can also investigate whether the current registrant is willing to transfer the domain through a legitimate process.
Before selecting an alternative, check for potential trademark conflicts.
A distinctive, memorable domain name can help strengthen your digital identity.
Can Different Domain Names Lead to the Same Website?
Yes.
Two or more domain names can point to the same website or online service.
For example, a company might register both tokokita.id and tokokita.com, then configure them to direct visitors to its primary website.
This can be achieved through DNS and server configurations or URL redirects.
Businesses often use this approach to protect their brand names and make their websites easier to find.
For SEO purposes, permanent redirects and canonical URLs can help search engines identify the preferred website address.
Can Similar Domain Names Cause Problems?
Yes.
Domain names that closely resemble existing brands may confuse internet users.
In certain cases, similar names may also lead to trademark disputes or identity misuse.
For example, a domain deliberately designed to resemble an official company website could be used for phishing or other fraudulent activities.
This is why checking a domain's legitimacy, reputation, and trademark implications is important.
Registering relevant domain variations may also help businesses protect their digital identities.
What Is PANDI's Role in Managing .id Domains?
In Indonesia, Pengelola Nama Domain Internet Indonesia (PANDI) serves as the registry operator for Indonesia's country-code top-level domain, .id.
PANDI manages the registry system and registration policies for .id domain names within its authority.
The registry helps ensure that the same domain name cannot be independently registered by two different parties at the same time.
PANDI also supports Indonesia's domain ecosystem through educational programs and collaboration.
Through coordinated domain management, .id domains can serve as digital identities for individuals, businesses, organizations, and institutions.
