A domain alias lets you point another domain name to the same website. This is useful when you own multiple domains for one brand (for example, example.com and example.net).
Before you start
- You must own the alias domain and be able to manage its DNS (nameservers or A records).
- The alias domain must already be registered (Plesk does not register domains).
Add a domain alias in Plesk
- Log in to Plesk (via My.GARMTECH).
- Go to Websites & Domains.
- Click Add Domain Alias.
- Select the primary domain (the website you want to point to).
- Enter the alias domain name (the additional domain).
- Choose options:
- Web service — keep enabled to show the website on the alias domain.
- Mail service — enable only if you want email addresses on the alias domain.
- DNS — if your domain uses GARMTECH nameservers, you can synchronize DNS zone with the primary domain.
- Redirect with HTTP 301 — recommended if you want all visitors to land on the primary domain (helps avoid duplicate content in search engines).
Click OK to create the alias.
Update DNS for the alias domain
For the alias domain to work, its DNS must point to your hosting:
- If you use GARMTECH nameservers: set NS to
ns1.garmtech.com, ns2.garmtech.com, ns3.garmtech.com.
- If you keep external DNS: create A/CNAME records that point to your hosting IP (see the DNS records article).
SSL certificate for the alias
Browsers will show a security warning if the alias domain is not covered by an SSL certificate. In most cases you can:
- Issue a Let’s Encrypt certificate and include the alias domain in the certificate, or
- Install a paid SSL certificate that covers both domains.
