5.3.4 DNS
DNS is a mechanism through which the URL's requested by users, such as www.avaya.com, are resolved into IP
addresses. These requests are sent to a Domain Name Server (DNS) server, which converts the URL to an IP address.
Typically the internet service provider (ISP) will specify the address of the DNS server their customers should use.
WINS (Windows Internet Name Service) is a similar mechanism used within a Windows network to convert PC and server
names to IP addresses via a WINS server.
If the system is acting as a DHCP server, in addition to providing clients with their own IP address settings it can also
provide them with their DNS and WINS settings if requested by the client.
Usability
· Mergeable: These settings are not mergeable. Changes to these settings will require a reboot of the system.
Configuration Settings
· DNS Service IP Address: Default = 0.0.0.0 (Do not provide DNS/Use DNS forwarding)
This is the IP address of a DNS Server. Your Internet service provider or network administrator provides this
information. If this field is left blank, the system uses its own address as the DNS server for DHCP client and forward
DNS requests to the service provider when Request DNS is selected in the service being used (Service | IP ).
· Backup DNS Server IP Address: Default = 0.0.0.0 (No backup)
· DNS Domain: Default = Blank (No domain)
This is the domain name for your IP address. Your Internet service provider or network administrator provides this.
Typically this field is left blank.
· WINS Server IP Address: Default = 0.0.0.0 (Do not provide WINS)
This is the IP address of your local WINS server. This is only used by Windows PCs, and normally points to an NT
server nominated by your network administrator as your WINS server. Setting a value will result in also sending a
mode of "hybrid".
· Backup WINS Server IP Address: Default = 0.0.0.0 (No backup)
· WINS Scope: Default = Blank (no scope)
This is provided by your network administrator or left blank.
