An edge hostname in a CNAME record on your DNS system allows you to route end user requests. When you create an edge hostname, you define rules that determine how CDN Pro handles requests from different client zones. A client zone is a combination of a geographical region and one or more ISPs (for example, "US+Comcast").
|Description||This field is auto-populated with the name of the person creating the new edge hostname. Accept or change this description as necessary.|
|Need this hostname to be resolved to edge servers in mainland China||Select whether traffic can be directed to servers in mainland China. Choices are:|
|Hostname||Either enter the first part of the edge hostname manually in the text field or click the Auto Generate button to generate a random one.|
Note: A default rule covering ALL regions and ALL ISPs will be created automatically if you don't define one.
|Client Region||Select a region that defines this client zone.|
|Client ISP||Select one or more ISPs that define this client zone.|
|Action Type||Select the type of action to be performed to requests from this client zone. |
|Server Group||If Action Type is set to Deliver, select one or more server groups to deliver the content for this client zone. CDN Pro servers are organized into 5 groups based on traffic cost from low to high: Standard, Premium, Premium+, Ultra, and nearChina. When you select one group, all the lower groups will be automatically included. |
Note: nearChina is a special server group that can be enabled for you if you want optimal performance serving Chinese visitors, but your domains lack ICP Beian. To enable this server group, contact the CDNetworks support team.
For more information, see About Server Groups below. To see the location of servers in each group, go to: https://www.cdnetworks.com/cdn360/.
|Enable IPv6||If Action Type is set to Deliver, select whether you want to enable IPv6 addressing.|
|Redirect Target||If Action Type is set to Redirect, specify an IP address or hostname to which CDN Pro will redirect your traffic.|
|Weight||When a client zone has multiple rules defined, each of them will be used randomly with a probability proportional to the weight specified here.|
|Has ICP Beian||This setting determines whether end user requests will be directed to and served by PoPs inside mainland China. |
When selecting a server group for the first time, we recommend that you create client zone rules that use the Standard server group, and then change to another server group if needed later.
If you create a client zone rule and select Premium, Premium+, or Ultra, all the lower priced groups will be included automatically and can be used to deliver content. For example, if you live in North America and want the best possible performance for your users, regardless of cost, choose Ultra.
When a user requests your content, the CDN Pro load balancer makes an intelligent routing decision based on the user's location and current network traffic, and then chooses an appropriate server to handle the request. The server that handles this request is located at any of the CDN Pro PoPs around the world and might be one listed as Standard, Premium, Premium+, or Ultra. Traffic used by different server groups is reflected in the Traffic Volume Summary report as well as in monthly invoices.
