Creating an Edge Hostname permalink

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").

  1. In the left pane, click Traffic Management.
  2. At the top right of the screen, click the Create Edge Hostname button.
  3. Complete the fields in the Create an Edge Hostname form. Required fields are denoted by an asterisk (*).

FieldsDescription
DescriptionThis 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 ChinaSelect whether traffic can be directed to servers in mainland China. Choices are:
  • No = traffic cannot be directed to servers in mainland China. (default)
  • Yes = traffic can be directed to servers in all regions including mainland China. Use this setting only for hostnames that have ICP Beian. Otherwise, requests directed to servers in mainland China will be rejected with the status code 451.
Note: This setting cannot be changed. If you need to change it, create a new edge hostname with the required setting and change your DNS settings to use that edge hostname instead.
HostnameEither enter the first part of the edge hostname manually in the text field or click the Auto Generate button to generate a random one.
  1. Click the Create Client Zone Rule button. The Create Client Zone Rule dialog box appears, with fields to define the client zone and how to handle requests come from it. Required fields are denoted by an asterisk (*).
    a. Complete all the fields, and then click the Create Client Zone Rule button.
    b. To specify more client zone rules, repeat steps 4 and 4a for each additional rule.

Note: A default rule covering ALL regions and ALL ISPs will be created automatically if you don't define one.

FieldsDescription
Client RegionSelect a region that defines this client zone.
Client ISPSelect one or more ISPs that define this client zone.
Action TypeSelect the type of action to be performed to requests from this client zone.
  • Deliver = contents will be served by CDN Pro servers to fulfill the requests from this client zone. Only one delivery action is allowed for each client zone. You need to select the server groups to deliver the contents.
  • Redirect = redirect client requests to another destination specified in the Redirect Target field (see below). This can be your origin site or another CDN provider. There can be multiple redirect actions for each client zone.
  • Reject = client requests will always receive a response with a 403 - forbidden error message. Only one reject action is allowed for each client zone.
Server GroupIf 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 IPv6If Action Type is set to Deliver, select whether you want to enable IPv6 addressing.
Redirect TargetIf Action Type is set to Redirect, specify an IP address or hostname to which CDN Pro will redirect your traffic.
WeightWhen a client zone has multiple rules defined, each of them will be used randomly with a probability proportional to the weight specified here.
  1. Expand Advanced Settings, and then confirm or change the following field.

FieldsDescription
Has ICP BeianThis setting determines whether end user requests will be directed to and served by PoPs inside mainland China.
  • No = this edge hostname will be used by a service hostname that does not have ICP Beian. It will not resolve to any server IP address in mainland China. Only server IP addresses outside China will be returned. (default)
  • Yes = all service hostnames using this edge hostname have ICP Beian. Visitors in mainland China can be served by local servers in China.

  1. Click the Create the Edge Hostname button.
  2. Add a CNAME record on your DNS server to point your service hostname(s) to the newly created edge hostname.

About Server Groups permalink

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.
