Specifying an alias (CNAME) record

This feature allows you to alias one host name to another. The target host name

does not need to be a member of the local domain. For example, you can create

an alias record from “news.domain.com” to “uucp.isp.net”.

To specify an alias (CNAME) record:

1. Select Server Management > Control Panel. The “Service Settings” table

appears.

2. Click the green pencil icon next to the DNS service in the “Service Settings”

table. The “DNS Settings for <sitename>” table appears.

3. Select Alias (CNAME) from the Add... pull-down menu.

4. Enter the host name and domain name for which you want to create an alias

(for example, www and mydomain.com) and enter the host name and

domain name for the target. The target host name is optional.

5. Click Update List.

6. Click Save Changes.

Conﬁguring a secondary DNS server

The RaQ XTR Administrator can conﬁgure a secondary DNS server to provide

redundant DNS service to your computers. If the primary DNS server is turned

off, a computer can use the secondary DNS server with no loss of performance.

Caution: Do not use an Alias (CNAME) Record to cause a domain

name to resolve to a host name.

For example, do not create an Alias (CNAME) Record for

mydomain.com that resolves to www.mydomain.com. Instead, add

a new Address (A) Record for mydomain.com to the IP address

used by www.mydomain.com. See “Conﬁguring a primary DNS

server” on page 246.
