Can I host only a subdomain (not a full domain name) of a website?
If you host a full domain name such as “example.com” with us, you can use subdomains like “blog.example.com”, too. Our setting up subdomains page has information about that.
Occasionally we’re asked a slightly different question: whether we can host a website subdomain like “blog.example.com” without also hosting the full “example.com” website, email or overall DNS for example.com.
That’s possible, but it’s non-standard, and you need to be careful about how you set it up.
Most customers do not need the information on this page. It’s only for customers doing something unusual by having us handle a small portion of their website, but having another organization host the rest of their site and their email.

Are you sure you need to do this?
First of all, you may not need to do this at all.
If you want us to handle everything related to your domain name (including email and DNS) except your www.example.com website, you might simply want to sign up with us and then add a custom DNS entry pointing www.example.com at another server. That’s much more standard.
You should only continue with the instructions below if you’re sure you want us to handle a subdomain such as “blog.example.com”, but don’t want us to handle any part of your email, DNS, or www.example.com site.
Sign up for the hosting account...
Even if you intend to have us handle only a subdomain of “example.com”, you still need to sign up for a hosting account transfer for that domain name with us. Just sign up normally, entering the “example.com” domain name on our order form. Signing up with us will not modify anything about your domain name because we don’t control your DNS records.
The order form will give you the option of transferring the domain name registration to our company, too. Most customers who want to host only a subdomain will probably prefer to keep the domain name registered elsewhere (which is simpler), but it’s up to you.
... but don’t update your DNS nameservers
After you sign up, you’ll receive our standard automated message saying you can update your “DNS nameservers” to point all of example.com at our company. However, you should ignore that message, because that’s not what you want to do.
Instead, contact us and tell us that you intend to host only a subdomain with our company. Send us this text (but with your actual subdomain if it’s different than “blog.example.com” so we can verify that it’s set up correctly):
We’ll adjust your account so you don’t receive any further reminders about updating the DNS.
Set up your content
Once you have a hosting account with us, set up your content as a subdomain of the domain name.
For example, if you want us to handle “blog.example.com”, you should set up your subdomain that way on our servers and test it using the temporary URL we send you (which would be “blog.example.com.customers.tigertech.net” in that case).
Point the subdomain at our servers
When you’re ready to make your subdomain “live”, edit your DNS entries to “point” your subdomain at our servers. The entry you create will look like this:
blog.example.com. IN CNAME example.com.customers.tigertech.net.
It is vitally important that you create a CNAME record and not an A record. You should not know or care what the IP address of the real domain name is on our servers. Using a CNAME ensures that it will keep working even if an IP address changes on our end; if you use an A record instead, it will eventually stop working.
Always use a CNAME record.
Never enter the IP address of one of our Web servers as an “A record” into another company’s DNS servers.
After you update your DNS entries and wait for the change to fully spread (or “propagate”) across the Internet, visitors to your subdomain will see the content on our servers.
If you used WordPress for the subdomain, you’ll want to change the WordPress settings to remove the extra “.customers.tigertech.net” from your URLs. From the WordPress Dashboard:
- Click Settings
- Click General
- Change both the “WordPress address (URL)” and “Site address (URL)” to the correct subdomain URL, removing “.customers.tigertech.net” from the end.
That’s all it takes.
Does this work for email?
Unfortunately not. It’s not possible to host only email subdomains with us. For example, we can’t host email for “lists.example.com” without hosting email for “example.com”. The instructions on this page only work for website subdomains.
