Using a Static IP Address Specified by Your Network AdministratorIf IP addresses for network devices are specified individually by your network administrator, you will need tomanually configure settings such as the IP address, subnet mask, default gateway, and DNS servers fromeither the base unit or one of the handsets.For details about the required network settings, consult your network administrator.DNS Server SettingsYou can configure the unit to use 2 DNS servers: a primary DNS server and a secondary DNS server. If youset both DNS servers, the primary DNS server receives priority over the secondary DNS server. If the primaryDNS server returns no reply, the secondary DNS server will be used.For details about configuring the DNS server settings using the base unit and handsets, or using the Web userinterface, see Configuring the Network Settings of the Unit in this section.DNS Priority Using Configuration FileThe setting for DNS server(s) may be configured using the configuration files by your phone system dealer(® see "DNS1_ADDR" and "DNS2_ADDR" in 4.4.2 DNS Settings).• If the DNS server addresses specified in the configuration file (® see "DNS_PRIORITY" in 4.4.2 DNSSettings) are given priority, the unit first sends its requests to those DNS servers. If a match is not found,the unit then sends its request to the DNS servers that were specified by the DHCP server, or the primary/secondary DNS servers that were specified on the unit or via the Web user interface.• If the DNS servers that were specified by the DHCP server, or the primary/secondary DNS servers thatwere specified on the unit or via the Web user interface are given priority, the unit first sends its requeststo those DNS servers. If a match is not found, the unit then sends its request to the DNS servers that werespecified using the configuration file.Configuring the Network Settings of the UnitThe following procedures explain how to change the network settings via each interface.For details about the individual network settings that can be configured via the base unit and handsets, or usingthe Web user interface, refer to the Quick Guide on the Panasonic Web site (® see Introduction) or see3.4.1 Basic Network Settings.Configuring Settings from the Base Unit (KX-TGP550 only)/HandsetTo configure network settings automaticallyIn cases when buttons/soft key icons are shown in English alphabet1.
