HITRON CVE-30360 USER’S GUIDE
CABLE
Your Internet Service Provider
You (or your network devices)
IANA is responsible for IP address allocation on a global scale, and your ISP assigns
IP addresses to its customers. You should never attempt to define your own IP
addresses on a public network, but you are free to do so on a private network.
In the case of the CVE-30360:
The public network (Wide Area Network or WAN) is the link between the cable
(CATV) connector and your Internet Service Provider. Your CVE-30360’s IP
address on this network is assigned by your service provider.
The private network (in routing mode - see Routing Mode on page 28) is your
Local Area Network (LAN) and Wireless Local Area Network (WLAN), if
enabled. You are free to assign IP addresses to computers on the LAN and
WLAN manually, or to allow the CVE-30360 to assign them automatically via
DHCP (Dynamic Host Configuration Protocol). IANA has reserved the following
blocks of IP addresses to be used for private networks only:
If you assign addresses manually, they must be within the CVE-30360’s LAN
subnet.
2.1.2.3 SUBNETS
A subnet (short for sub-network) is, as the name suggests, a separate section of a
network, distinct from the main network of which it is a part. A subnet may contain all
of the computers at one corporate local office, for example, while the main network
includes several offices.
In order to define the extent of a subn
et, and to differentiate it from the main network,
a subnet mask is used. This “masks” the part of the IP address that refers to the main
network, leaving the part of the IP address that refers to the sub-network.
Each subnet mask has 32 bits (binary digits), as does each IP address:
A binary value of 1 in the subnet mask indicates that the corresponding bit in the
IP address is part of the main network.
A binary value of 0 in the subnet mask indicates that the corresponding bit in the
IP address is part of the sub-network.
