Adding and Managing Hostnames

In common usage today, hostname refers specifically to the Fully Qualified Domain Name (FQDN) that identifies a computer or device on a computer network. The domain name is the part of a network address that identifies it as belonging to a particular domain. The host name and the domain labels are separated by periods. The total length of the hostname as an FQDN cannot exceed 255 character with each domain name label having a maximum length of 63 characters.

For example, if a company's domain name is "example.com." and a particular computer in the company has been named "plato", the hostname for that computer will be "plato.example.com.". Note, that technically FQDNs end in a period to unambiguously define the hostname and to be sure that it is not part of a longer domain name. (although in common usage this final period is often omitted).

To add a Hostname that will be able to access your account, or manage existing Hostnames that you have already added, click on Delivery Options and then the Hostnames submenu. The Host Manager screen, illustrated below, is displayed. Follow the steps below to add or mange the Hostnames associated with your account.

Note: When you add a Hostname to your account, the changes take 5-10 minutes to propagate to all locations worldwide. Once you have configured your alias here, you still have to Update your DNS (see the link within the header of this screen for instructions) to point traffic to CacheFly.

 

  1. Enter a unique hostnamename  in the Add a new hostname field, and then click Create a new host. As shown in the following illustration, the system confirms that the hostname has been created, and it is displayed within the Manage hostnames portion of the screen

After configuring a custom hostname for your CacheFly account using the Hostname Manager, you (or your primary hosting company) must make changes to your DNS Zone File in order to actually point requests to your CacheFly account.   The cname should be main to your primary CacheFly account now.

 Example:

If your username is: myusername, and you're adding static.mydomain.com, you would configure:

static.mydomain.com. 86400 IN CNAME myusername.cachefly.net In your DNS Zone File

Note: To remove a hostname from the "Hostname" list, select it on the list and click Remove selected..As shown in the following illustration, the system displays a Warning message before proceeding with the deletion, to ensure that is your intention. Click Remove to remove the hostname, or click Cancel to close the message without deleting it.
