Conettix Ethernet Communication Module
Selection: 0.0.0.0 to 255.255.255.255
This parameter sets a static IPv4 address for the module if DHCP is disabled.
IPv4 Subnet Mask
Default: 255.255.255.0
Selection: 0.0.0.0 to 255.255.255.255
Subnetting is used to break the network into smaller, more efficient subnets to prevent
excessive rates of Ethernet packet collision in the large network. A significant feature of
subnetting is the subnet mask. Applying a subnet mask to an IP address allows you to identify
the network and node parts of the address. When DHCP/AutoIP Enabled is set to Yes, this
parameter cannot be changed.
IPv4 Default Gateway
Default: 0.0.0.0
Selection: 0.0.0.0 to 255.255.255.255
A gateway is a point (typically a router) on a TCP/IP network that serves as an access point to
another network. A host uses a default gateway when an IP packet's destination address
belongs to someplace outside the local subnet. The default gateway address is usually an
interface belonging to the LAN's border router. In DHCP mode, the default gateway is usually
resolved automatically. When DHCP/AutoIP Enable is set to Yes, this parameter cannot be
changed.
Obtain IPv4 DNS Server Address Automatically
Default: Yes
Selection: Yes, No
Setting this parameter to No allows entering the server address. Setting this parameter to Yes
clears addresses and prevents address entry.
IPv4 DNS Server IP Address
Default: 0.0.0.0
Selection: 0.0.0.0 to 255.255.255.255
A Domain Name Server (DNS) converts internet domain names or hostnames to their
corresponding IP addresses. This setting is used to configure a DNS server address in Static IP
mode. In DHCP mode, the default value of 0.0.0.0 indicates the DHCP server's default DNS is
used. To use a custom DNS server in DHCP mode, change the parameter to the specified DNS
server's IP address.
The address has a dot decimal notation, which consists of the four octets of the address
expressed separately in decimal and separated by periods. Each octet has a value 0-255.
Alternate IPv4 DNS Server IP Address
Default: 0.0.0.0
Selection: 0.0.0.0 to 255.255.255.255
This parameter provides an alternate IPv4 DNS server IP address.
The address has a dot decimal notation, which consists of the four octets of the address
expressed separately in decimal and separated by periods. Each octet has a value 0-255.
