within that time, e-mail cannot be sent. Therefore, use DNS servers on the same segment as the
NMC or on a nearby segment (but not across a wide-area network [WAN]).
– After you define the IP addresses of the DNS servers, verify that DNS is working correc tl y by
entering the DNS name of a computer on your network to look up the IP address for that
computer.
• Host Name: After you configure a host name here and a domain name in the Domain Name field,
users can enter a host name in any field in the NMC interface (except e-mail addresses) that accepts a
domain name.
• Domain Name (IPv4): You need to configure the domain name here only. In all other fields in the
NMC interface (except e-mail addresses) that a ccept domain names, the NMC adds this domain name
when only a host name is entered.
– To override all instances of the expansion of a specified host name by the addition of the domain
name, set the domain name field to its default, somedomain.com, or to 0.0.0.0.
– To override the expansion of a specific host name entry (for example, when defining a trap
receiver), include a trailing period. The NMC recognizes a host name with a trailing period (such
as mySnmpServer.) as if it were a fully-qualified domain name and does not append the
domain name.
• Domain Name (IPv6): Specify the IPv6 domain name here.
• Select test to send a DNS query that tests the setup of your DNS servers:
–As Query Type, select the method to use for the DNS query, see table below
–As Query Question, identify the value to be used for the selected query ty pe:
– View the result of the test DNS request in the Last Query R esponse field.
