For example, the domain name zyxel.com is hooked up to a record named A which translates it to
11.22.33.44. You also have several subdomains, like mail.zyxel.com, ftp.zyxel.com and you want
this subdomain to point to your main domain zyxel.com. Edit the IP Address in record A and all
subdomains will follow automatically. This eliminates chances for errors and increases efficiency in
DNS management.
30.6.7 Adding a CNAME Record
Click the Add icon in the CNAME Record table to add a record. Use “*.” as a prefix for a wildcard
domain name. For example *.zyxel.com.

30.6.8 Domain Zone Forwarder
A domain zone forwarder contains a DNS server’s IP address. The USG can query the DNS server to
resolve domain zones for features like VPN, DDNS and the time server. A domain zone is a fully
qualified domain name without the host. For example, zyxel.com.tw is the domain zone for the
www.zyxel.com.tw fully qualified domain name.

DESCRIPTION
Alias name
Enter an Alias Name. Use "*." as a prefix in the Alias name for a wildcard domain
name (for example, *.example.com).
FQDN
Type a Fully-Qualified Domain Name (FQDN) of a server. An FQDN starts with a
host name and continues all the way up to the top-level domain name. For
example, www.zyxel.com.tw is a fully qualified domain name, where “www” is
the host, “zyxel” is the third-level domain, “com” is the second-level domain,
and “tw” is the top level domain. Underscores are not allowed.
Use "*." as a prefix in the FQDN for a wildcard domain name (for example,
*.example.com).
