Aliases, meaning additional domains operating on the webhosting, can only be set up for NoLimit and NoLimit Extra webhostings. LowCost does not support aliases.
You can change the Webhosting plan according to the instructions Services – Change plan or billing period.
In this guide, you will learn:
- What aliases are used for
- How to add or remove an alias on Webhosting
- How to set up an alias for:
- Common problems
- Frequently asked questions
Webhosting aliases
You can point an additional 3 domains as aliases to the space of each NoLimit and NoLimit Extra Webhosting. If you need to operate more domains on the hosting, you can increase this number by purchasing the Unlimited number of aliases add-on. LowCost Webhosting does not support aliases.
Through aliases, you can operate multiple different websites on one Webhosting. These websites share:
- Webhosting performance: Individual websites on Webhosting share processes reserved for the entire Webhosting, which places higher demands on optimization.
- Email mailboxes: Email space and individual mailboxes are shared for aliases. More information can be found in the chapter Email mailboxes for different domains.
Alternatively, you can use aliases for redirection with the HTTPS protocol. More information can be found in the chapter Redirecting with HTTPS.
Adding and removing an alias
Before adding an alias to a webhosting, make sure that:
- The (sub)domain being added is not the name of an existing alias, Webhosting, Mailhosting, or WebSite service. If you already have such a service in your customer account, remove its alias or rename it according to the instructions Webhosting – Renaming, Mailhosting – Renaming, or WebSite – Renaming.
- The domain being added is at least temporarily in the same customer account as the Webhosting to which you are adding the alias. If not, move it according to the instructions Services – Transfer between accounts, or Domains – Transfer between accounts using an authorization password. This limitation applies only to domains registered with VEDOS; domains registered elsewhere do not need to be moved in any way. Alternatively, ask the customer whose account contains the domain to grant you authorization according to the instructions Administration – Authorized user.
Until these conditions are met, the system will not allow the alias to be added.
Alias management interface
You can access alias management by following these steps:
- Log in to the customer administration ⧉.
- In the top menu, select Hosting services Webhosting.
- Select the service from the list of webhostings to which you want to add the alias.
- In the left menu, select Aliases.

We also recommend using the WEDOS DNS servers for the domain. This can automate part of the next steps.
Adding an alias
Changes in the system take effect within 30 minutes, DNS record changes within 1 hour.
Enter the alias domain in the form domain.tld. Avoid a name that contains the www subdomain.
Add an alias to Webhosting by following these steps:
- Enter the alias management interface according to the chapter Alias management interface.
- In the New alias box, fill in the alias domain.
- Decide whether to automatically set up DNS and generate a Let’s Encrypt certificate.
- Click the Add alias button.

If you use WEDOS DNS servers, you can automatically point the domain to the webhosting with the alias. The option make changes on our DNS servers for the alias domain is selected automatically. The system automatically changes A, AAAA record types and MX for the given (sub)domain. DNS record changes will take effect within 1 hour.
If the domain is already pointed to the webhosting from an earlier time, you can automatically include the alias domain in the Let's Encrypt certificate. If the domain is not already pointed, the system will wait 10 minutes for DNS propagation when this option is checked and then attempt to generate the certificate.
Removing an alias
To remove an alias, follow these steps:
- Enter the alias management interface according to the chapter Alias management interface.
- In the alias overview, click the cross icon next to the name of the alias you want to remove.
- Confirm the deletion of the alias.

Alias settings
You can use an alias to operate multiple websites and emails on one Webhosting, or for redirection (with HTTPS).
Multiple websites on one Webhosting
By default, aliases display the contents of the www folder on the Webhosting FTP. Therefore, on the domain and subdomains of the alias you see the same content as on the main domain (if its content is in the www folder).
A detailed guide to setting up separate alias websites can be found in the article Webhosting – Separate websites for aliases.
Email mailboxes for different domains
By default, Webhosting mailboxes are shared by alias domains. For example, the mailbox info@domena.tld is shared (identical) with the mailbox info@alias.tld.
If you need to distinguish mailboxes, you can set up so-called identities in WebMail ⧉. A detailed guide can be found in the article WebMail – Alias email mailboxes (identities).
Redirecting with HTTPS
Basic domain redirection does not support the https protocol because the redirect server does not have, and cannot have, an SSL certificate issued for the given domain. On your own Webhosting, you can issue a certificate for the alias domain (and its subdomains).
Instructions for redirecting a domain with HTTPS can be found in the article Webhosting – Domain redirection with HTTPS.
Common problems
Common problems with alias setup include:
- The domain cannot be added as an alias
- Domain in another customer account
- Problem when adding to the Let's Encrypt certificate
- URL in the form domain.tld/domains/domain.tld
The domain cannot be added as an alias
Problem: The error displayed is: The domain cannot be added as an alias – a separate webhosting exists for the domain.
Cause: The domain already has another service assigned to it – Webhosting, WebSite, or Mailhosting.
Solution: Rename the conflicting service according to the renaming instructions for Webhosting, WebSite, or Mailhosting, or remove the conflicting webhosting alias.
Domain in another customer account
Problem: The error displayed is: The domain is located in another customer account.
Cause: If the domain is registered by WEDOS, you can use its name for security reasons only if it is located (at least temporarily) in your customer account, or if you have permissions set for it.
Solution: Arrange for the domain to be transferred to your account according to the instructions Services – Transfer between accounts. After adding the alias or renaming, you can transfer the services back to your customer accounts in the same way.
Alternatively, ask the customer whose account contains the domain to grant you authorization according to the instructions Administration – Authorized user.
Problem adding to the Let's Encrypt certificate
Problem: The error displayed is: A problem was detected when adding the following domains to the Let’s Encrypt certificate.
Cause: The most common cause of a problem adding to the Let's Encrypt certificate is an incorrect DNS pointing. Less commonly, it may be a temporary outage or maintenance of the certification authority.
Solution: Make sure the DNS records are correctly pointed to the webhosting. For this, you can use, for example, domain/webhosting diagnostics. Note – if there was a change of DNS servers (NSSET) within the last 48 hours or a change of DNS records within the last hour, the results may not be current.
In case of errors, complete the HTTPS setup manually according to this guide.
URL domain.tld/domains/domain.tld
Problem: The website displays the folder address in the browser's address bar.
Solution: Make sure that in the PHP code you obtain the current path using the variable $_SERVER[„REQUEST_URI“].
If you use a content management system, make sure that the base address is set correctly, for example according to the community guides for:
Frequently asked questions
How many websites can I operate on one Webhosting at most?
This number is determined by the performance of the webhosting plan and by application usage. While Webhosting performance is clearly defined, application requirements depend on its optimization and traffic. Outside of peak times, several WordPress sites can run on the service without problems, but during peak traffic or under attack, even one relatively undemanding website can end up with a 503 Error.
