SonicWALL TZ 190 Manuale Utente

The SonicWALL security appliance has a DNS lookup tool that returns the IP address of a 
domain name. Or, if you enter an IP address, it returns the domain name for that address. 

Enter the host name or IP address in the Look up name field. Do not add http to the host name. 

The SonicWALL security appliance queries the DNS Server and displays the result in the 
Result section. It also displays the IP address of the DNS Server used to perform the query. 

The DNS Name Lookup section also displays the IP addresses of the DNS Servers configured 
on the SonicWALL security appliance. If there is no IP address or IP addresses in the DNS 
Server fields, you must configure them on the Network > Settings page. 

Find Network Path indicates if an IP host is located on the LAN or WAN ports. This can 
diagnose a network configuration problem on the SonicWALL security appliance. For example, 
if the SonicWALL security appliance indicates that a computer on the Internet is located on the 
LAN, then the network or Intranet settings may be misconfigured.

Find Network Path can be used to determine if a target device is located behind a network 
router and the Ethernet address of the target device. It also displays the gateway the device is 
using and helps isolate configuration problems.
