Aliases, that is, additional domains running on Webhosting, can only be set up for NoLimit and NoLimit Extra webhosting. LowCost does not support aliases.
You can change the webhosting plan according to the instructions Webhosting – Plan change.
In this guide you will learn:

Webhosting Aliases
You can point up to 3 additional domains to each NoLimit and NoLimit Extra Webhosting space as aliases. If you need to run more domains on the hosting, you can increase this number by purchasing the Unlimited number of aliases add-on service. Webhosting LowCost does not support aliases.
Through aliases, you can run 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 storage 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 HTTPS redirecting. More information can be found in the chapter HTTPS redirect.
Adding and removing an alias
Before adding an alias to a webhosting service, 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 – Rename, Mailhosting – Rename, or WebSite – Rename.
- The domain being added is at least temporarily in the same customer account as the Webhosting to which you are adding the alias. If it is not, move it according to the instructions Services – Move between accounts, or Domains – Move between accounts using an authorization password. This limitation applies only to domains registered with VEDOS; domains registered elsewhere do not need to be moved at all. Alternatively, ask the customer whose account the domain is in to grant you authorization for it 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
To manage aliases, follow these steps:
- Log in to the customer administration ⧉.
- In the top menu, select Hosting services Webhosting.
- From the list of webhostings, select the service to which you want to add an alias.
- In the left menu, select Aliases.

We also recommend using the WEDOS DNS servers for the domain. This can automate part of the following steps.
Adding an alias
Changes in the system will take effect within 30 minutes; DNS record changes within 1 hour.
Enter the alias domain in the form domain.tld. Avoid a name that includes the www subdomain.
To add an alias to Webhosting, follow these steps:
- Enter the alias management interface according to the chapter Alias management interface.
- In the New alias box, enter the alias domain.
- Decide on automatic DNS setup and Let’s Encrypt certificate generation.
- Click the Add alias button.

If you use WEDOS DNS servers, you can have the domain automatically pointed to the webhosting with the alias. The option make changes on our DNS servers for the alias domain is selected automatically. The system will automatically change the A, AAAA record types and MX for the given (sub)domain. DNS record changes will take effect within 1 hour.
If the domain has already been pointed to the webhosting previously, you can automatically include the alias domain in the Let’s Encrypt certificate. If the domain has not been pointed in advance, 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 deletion of the alias.

Alias setup
You can use an alias to run multiple websites and email accounts on one Webhosting, or for redirecting (with HTTPS).
Multiple websites on one Webhosting
By default, aliases display the content of the www folder on Webhosting FTP. So on the alias domain and subdomains, 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@domain.tld is shared (identical) with the mailbox info@alias.tld.
If you need to distinguish the mailboxes, you can set up so-called identities in WebMail ⧉. A detailed guide can be found in the article WebMail – Alias email mailboxes (identities).
HTTPS redirect
Basic domain redirect does not support https 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 redirect with HTTPS.
Common issues
Common issues 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 following error is displayed: 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 following error is displayed: The domain is 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 set permissions for it.
Solution: Arrange for the domain to be moved to your account according to the instructions Services – Move between accounts. After adding the alias or renaming, you can move the services back to your customer accounts in the same way.
Alternatively, ask the customer whose account the domain is in to grant you authorization for it according to the instructions Administration – Authorized user.
Problem adding to the Let’s Encrypt certificate
Problem: The following error is displayed: A problem was detected when adding the following domains to the Let’s Encrypt certificate.
Cause: The problem with adding the domain to the Let’s Encrypt certificate is most often caused by a DNS pointing error. Less often, it may be a temporary outage or downtime of the certification authority.
Solution: Make sure the DNS records point correctly to the webhosting. For this, you can use for example the domain/webhosting diagnostics. Caution – if there has been a change of DNS servers (NSSET) in the last 48 hours or a change of DNS records in the last hour, the results may not be current.
If errors occur, 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 address bar.
Solution: Make sure that in your PHP code you determine the current path using the variable $_SERVER[„REQUEST_URI“].
If you use a CMS, make sure that the base URL is set correctly, for example according to community guides for:
Frequently asked questions
What is the maximum number of websites I can run on one Webhosting?
This number is determined by the performance of the webhosting plan and by the application’s consumption. While Webhosting performance is clearly defined, application requirements depend on its optimization and traffic. Off-peak, several WordPress sites can run on the service without problems, but during peak times or under attack, even one relatively undemanding website may end up with a 503 Error.
