DataSafe NAS User’s Manual 21
adds a terminating period and then queries DNS using
that name.
However, if you enter a single-label, unqualified
name, or a multiple-label, unqualified name, and the
name fails to resolve as an FQDN, the resolver
systematically appends different DNS suffixes to the
name that you entered, adding periods to make them
FQDNs. The resolver then resubmits the name to DNS.
If you have not entered a domain suffix search list, the
DNS resolver appends the following names:
1. The primary DNS suffix.
2. If the DNS suffix does not successfully resolve
after you enter the DNS name, the resolver
appends each connection-specific DNS suffix.
This suffix can be dynamically assigned by the
DHCP server. You can also specify suffixes on the
DNS tab in the Global Network Settings.
From the primary menu bar, select Network
Setup, then click Global Network Settings.
If DNS name resolution is still unsuccessful, the DNS
resolver devolves the FQDN by appending the parent
suffix of the primary DNS suffix name, and the parent
of that suffix, and so on, until only two labels are left
On the other hand, if you have entered a list of specific
DNS suffixes, both the primary DNS suffix and the
connection-specific domain name are ignored. In such
a case, neither is appended to the host name before
the FQDN are submitted to DNS. Instead, the resolver
appends each suffix from the search list in order, and
then submits the name to the DNS server until the
resolver finds a match or reaches the end of the list.
For example, if you enter the name client, and the
primary DNS suffix is eu.reskit.com, the resolver will
first try client.eu.reskit.com, and then
client.reskit.com.
