Prolog information
These settings configure the DNS servers to which the IP Office system should send DNS request when it needs to resolve name addresses into numeric IP addresses.
  • DNS is a mechanism through which the URL's such as www.avaya.com are resolved into IP addresses. Typically the customer's internet service provider (ISP) specifies the address of the DNS server their customers should use. In more complex networks, the customer may host their own DNS server.
  • WINS (Windows Internet Name Service) is a mechanism used within a Windows network to convert PC and server names to IP addresses using a WINS server.
If the IP Office system is acting as a DHCP server, in addition to providing clients with their IP address settings, it can also provide them with their DNS and WINS settings if requested by the client.
These settings must be edited offline. To enter offline editing, select Menu Bar Current User IconOffline Mode.

Configuration Settings

Field
Description
DNS Service IP Address
Default = 0.0.0.0 (Do not provide DNS/Use DNS forwarding)
The IPv4 address of the DNS Server.
  • If left at the default, the IP Office system uses its own LAN address as the DNS server for DHCP clients and forward DNS requests to the service provider when Request DNS is selected in the service being used (ServiceIP).
  • The IP Office does not support DNS priority. If the DNS response contains multiple addresses with priority, the IP Office only uses the first address.
Backup DNS Server IP Address
Default = 0.0.0.0 (No backup)
The alternate IPv4 DNS server address used if the server address above does not respond.
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 used by Windows PCs to connect to the NT server that is the network WINS server. Setting a value will result in sending a mode of "hybrid".
  • WINS settings are not supported on Linux-based IP Office systems.
Backup WINS Server IP Address
Default = 0.0.0.0 (No backup)
This is alternate WINS server address used if the server address above does not respond.
WINS Scope
Default = Blank (no scope)
This is provided by your network administrator or left blank.
