The network part of the IP address is the same for all hosts on the same subnet, and the
remainder is unique to each host. As shown in the table below, a Subnet Mask of
255.255.255.0 (a class C mask) identifies 24 bits for the network portion and 8 bits for the
host portion. Most users will not need to change the default Subnet Mask setting of
255.255.255.0.
CLASS SUBNET MASK NETWORK ADDRESS HOST ADDRESS
A 255.0.0.0 8 bit 24 bit
B 255.255.0.0 16 bit 16 bit
C 255.255.255.0 24 bit 8 bit
Default Gateway
Specifies the IP address of the gateway host, if available on the network.
NOTE The Default Gateway setting will be grayed out when the Use DHCP Server checkbox is enabled.
The value shown is the gateway assigned by the DHCP server.
The gateway host is responsible for sending and receiving data between hosts on
different networks, routing data packets from a device on the local subnet to a device on
another subnet.
For example, if a 1700 reader will need to communicate with a remote host on a different
subnet, enter the address of the gateway device in the Default Gateway field. However, if
the reader will need to communicate only with devices on the local subnet, do not enter
an address for the Default Gateway (leave the field all zeros).
DNS Server
Specifies the IP address of the host on the network providing DNS resolution, if available.
NOTE The DNS Server setting will be grayed out when the Use DHCP Server checkbox is enabled. The
value shown is the DNS Server assigned by the DHCP server.
A Domain name (i.e., yourcorp.com) is an alias for an IP address (i.e., 192.168.0.1). A
DNS (Domain Name Server) maintains the data on corresponding domain names and IP
addresses. The DNS Server setting determines which host is contacted (by IP address)
in response to a given Domain Name.
Host Name
Assigns a name, or “alias” for the reader as it will appear when browsing the network
using the In-Sight PC Host.
Each 1700 reader has its host name set automatically the first time it boots. The format is
“is17xxxxxx", where “xxxxxx" consists of the last 24 bits of the reader’s unique MAC
address. For example, a reader with the MAC address 00-d0-24-00-06-0b will be
assigned the host name, "is1700060b".
NOTE The Host Name setting is not automatically assigned by the DHCP server (if used) or referenced
through the DNS server. If the Use DHCP Server checkbox is enabled and the DHCP server
supplies the Host Name, it is ignored in favor of the default host name or the name entered by the
user.
