Configuring Domain Name System (DNS) Characteristics
The following example shows the procedure for and results of configuring the default
name resolution to FINANCE.ACME.COM:
Using Trailing Dots
The access server uses a sequence of name resolution attempts when you enter a host
name without a trailing dot at the end of the domain name. If you end a name with a
trailing dot, the access server does not use a sequence of name resolution attempts.
Instead it uses the domain name as you enter it.
For example, suppose that you enter:
Local> CONNECT SALES.REVENUE.
Because this domain name ends with a dot, the access server does not append the
default name resolution domain or any part of that domain.
Step Action
1 Define the default name resolution domain as follows:
Local>
CHANGE INTERNET NAME RESOLUTION DOMAIN
FINANCE.ACME.COM
2 Enter the following connect command:
Local>
CONNECT SALES
3 In this situation, the access server automatically appends the default
name resolution domain to SALES. The access server behaves as if you
had typed:
Local>
CONNECT SALES.FINANCE.ACME.COM
4 Enter a command with a higher level domain name:
Local>
CONNECT SALES.REVENUE
Result:
The access server tries a sequence in the following order, using
parts of the default domain name:
SALES.REVENUE.FINANCE.ACME.COM
SALES.REVENUE.ACME.COM
SALES.REVENUE
The name is likely to be resolved correctly as the access server tries
SALES.REVENUE.ACME.COM. The sequence terminates at that
point.
