About the DNS Domain Name
The DNS
Domain Name
is used when attempting to resolve
server addresses configured on the VCS that are without
any form of qualification (e.g.
ldap
or
ldap_server
but not
ldap.server
). It applies only to the following:
LDAP server
•
NTP server
•
External Manager server.
•
The DNS
Domain Name
is appended to the unqualified server
address before a query to the DNS server is executed.
If the server address is an IP address or is in the format of a
domain name, DNS will only be queried for the server address
as configured, without the DNS
Domain Name
appended. For
this reason we recommend that all server addresses use an IP
address or FQDN (Fully Qualified Domain Name).
The DNS Domain name plays no part in URI dialing.

Overview
About DNS Servers
You must specify at least one DNS server to be queried for
address resolution if you wish to either:
use FQDNs (Fully Qualified Domain Names) instead of IP
•
addresses when specifying external addresses (for example
for LDAP and NTP servers, neighbor zones and alternates), or
use features such as
•
,
You can specify up to 5 DNS servers. The VCS sends requests
to all configured servers in parallel taking the first result
received and discounting the rest.

This can lead to confusing behavior should local network
administrators, for example, deploy ‘split horizon’ DNS
where records held on an internal, corporate, DNS
server use the same domain names but with different values to
those on the public internet - an often used tactic in corporate
intranets.
