IP Address
The Internet Protocol (IP) address is a unique 32-bit number used to identify the host computer connected to a TCP/IP
network. The value of the IP Address is represented in a dotted decimal format. WebShare assigns 192.168.0.1 to this
address by default. This value may be changed to any valid IP address e.g. an existing address assigned for local LAN
administration. Note: If the default IP Address needs to be changed, the DHCP Base and End addresses will also have to be
adjusted. All changes will be entered in the LAN Advanced Configuration screen.
Subnet Mask
The subnet mask is a 32-bit number used to identify the network and host segments of an IP address. This value is
represented in the same dotted decimal format as the IP address. This is the subnet mask associated with the IP address
above. This value should not be set to a subnet address greater than 255.255.255.248 to accommodate the WebShare IP.
The default value for the subnet mask is 255.255.255.0.
Domain Name System (DNS) Primary
The domain naming system is a convention used for identifying computers attached to the Internet or a Local Area Network
(LAN). DNS maps a name to its corresponding IP address. A host desiring to resolve a domain name to the IP address uses
the main DNS server. The secondary or backup DNS server performs the same function as the main server.
This IP address represents the address that WebShare uses to respond to primary DNS queries from your computer.
The default value is 192.168.0.2.
Domain Naming System (DNS) Secondary
This IP address represents the address that WebShare uses to respond to secondary DNS queries from your computer.
The default value is 192.168.0.3.
Dynamic Host Configuration Protocol (DHCP)
DHCP is a protocol used to automate the administration of IP addresses within a local area network. A server provides the
IP allocation for computer hosts that are running a DHCP client. This controls the state of the local WebShare DHCP
Server.
The default value is enabled.
Static NAT
If enabled, Static NAT makes it possible to specify an IP address to which WebShare should direct unsolicited inbound
traffic. For example, it lets you allow users on the Internet to access your local Web server.
The default value is enabled.
