Domain name is the default domain the host is in (such as
alcatel-sbell.com.cn). Usually, this gets appended to names entered on the
client when trying to do DNS resolution - so if you enter http://www/, the
resolver would look up www.alcatel-sbell.com.cn. FQDN is the fully-qualified
domain of the host - this might be myhost.alcatel-sbell.com.cn.

Generally speaking, the FQDN is likely the "host-name" option + "." + the
"domain name" option, but this doesn't have to be case.
