The IP address is the address information allocated to each device connected to a TCP/IP network.
In the IPv4 (Internet Protocol version 4) format, the 32-bit address is divided into four 8-bit sections and
represented as "192.168.0.2" for example.
On a TCP/IP network, the IP address is used to identify network devices.
In addition to the IP address, a TCP/IP network also uses the port number as the auxiliary address to identify
individual programs running on the networked computers.
Assuming that the IP address represents a company address, the port number is a contact number; and the
actual data transmission occurs based on the combination of the IP address and the port number.
The port number is represented as a 16-bit number and specified in the range of 0 to 65535.
DHCP is a protocol used by a network server to automatically allocate IP address and other network information
to clients on the network.
The subnet mask refers to the value used to obtain the network address of a subnet (segment) from an IP
address in a subnetted network.
In the IP address, the portion excluding the network address is the host address, which is used to identify
individual computers on the network.
On the camera's IP ADDRESS SETTING screen, you set the default gateway, which serves as a relay contact
point when communicating with external networks. Terminal PCs will transmit data to the default gateway.
