IP address of 10.10.100.27 is assigned a host name of accounts015 and another IP address of 10.10.100.33 is assigned a host name of sales021, then the switch configured with the domain suffix evergreen.trees.org and a DNS server that resolves addresses in that domain can use the host names to reach the devices with ping and traceroute commands:
ping accounts015 traceroute sales021
Basic Operation
■When the switch is configured with only the IP address of a DNS server available to the switch, then a ping or traceroute command, executed with a fully qualified domain name, can reach a device found in any domain accessible through the configured DNS server.
■When the switch is configured with both of the following:
•the IP address of a DNS server available to the switch
•the domain suffix of a domain available to the configured DNS server
then:
•A ping or traceroute command that includes the host name of a device in the same domain as the configured domain suffix can reach that device.
•A ping or traceroute command that includes a fully qualified domain name can reach a device in any domain that is available to the configured DNS server.
Example. Suppose the switch is configured with the domain suffix mygroup.procurve.net and the IP address for an accessible DNS server. If an operator wants to use the switch to ping a host using the DNS name “leader” assigned to an IP address used in that domain, then the operator can use either of the following commands:
ProCurve# | ping leader |

Figure 3. Example of Using Either a Host Name or a Fully Qualified Domain Name
In the preceeding example, if the DNS server’s IP address is configured on the switch, but a domain suffix is not configured, then the fully qualified domain name must be used.
Note that if the target host is in a domain other than the domain configured on the switch, then:
