6.2.2.10.1 (CONFIG: IP) Addresses

Gateway:192.001.001.100 ()
Use the arrow keys to select a parameter. Press ENTER.
CAUTION
Carefully review the following information:
1) Depending on the IP Address mask (“/24” in this example) certain IP addresses are reserved
for Network Address and Broadcast Addresses. These addresses are the lowest and highest
IP addresses allowable in the mask, and are not allowed to be used as the modem’s IP
address. In this case, the Network Address is 192.168.1.0 and the Broadcast Address is
192.168.1.255. Entry of a Network or Broadcast Address will be rejected by the modem.
2) The following IP addresses may NOT be entered as the modem’s IP Address; because they
are used internally, they violate common networking practice, and they will cause network
issues:
Reason this IP Address cannot be used
Non-routable address per RFC 1122
127.0.0.0 – 127.255.255.255
127.X.X.X reserved for loopback addresses
Internal IP Subnet used by modem
Internal IP Subnet used by modem
224.0.0.0 – 239. 255.255.255
Multicast IP Address range
240.0.0.0 – 255. 255.255.255
Experimental IP Address range
Cannot be the lowest or highest address allowable in the subnet mask
unless the mask is /32
3) The following rules apply to the subnet mask and must be held to as they violate common
networking practice and will cause network issues:
Classful network: Subnet Make must be ≥16 bits
Classful network: Subnet Make must be ≥24 bits
Subnet Mask must be 8-30 bits or 32
(CONFIG: IP) Addresses IP:
To configure the IP Address for the Ethernet M&C J4 | MGMT port: Use the arrow keys to
select a digit, and then use the arrow keys to change that digit. Press ENTER.
