Log > Name Resolution

TIP: The Log > Name Resolution page includes settings for configuring the name servers used to resolve IP addresses and server names in the log reports.

The Dell SonicWALL network security appliance uses a DNS server or NetBIOS to resolve all IP addresses in log reports into server names. It stores the names/address pairs in a cache, to assist with future lookups. You can clear the cache by clicking Reset Name Cache in the top of the Log > Name Resolution page.

•	Selecting Name Resolution Settings

•	Specifying the DNS Server

Selecting Name Resolution Settings

The firewall appliance can use DNS, NetBIOS, or both to resolve IP addresses and server names.

In the Name Resolution Method list, select:

•	None: The security appliance will not attempt to resolve IP addresses and Names in the log reports.

•	DNS: The security appliance will use the DNS server you specify to resolve addresses and names.

•	NetBIOS: The security appliance will use NetBIOS to resolve addresses and names. If you select NetBIOS, no further configuration is necessary.

•	DNS then NetBIOS: The security appliance will first use the DNS server you specify to resolve addresses and names. If it cannot resolve the name, it will try again with NetBIOS.

Specifying the DNS Server

You can choose to specify DNS servers, or to use the same servers as the WAN zone.

1	Select Specify DNS Servers Manually or Inherit DNS Settings Dynamically from WAN Zone. The second choice is selected by default.

2	If you selected to specify a DNS server, enter the IP address for at least one DNS server on your network. You can enter up to three servers.

3	Click Accept in the top left corner of the Log > Name Resolution page to make your changes take effect.
