172.16.1.14 255.255.255.240
IP address and Subnet Mask... :D
The network address of an IPv4 address of 192.168.7.5 with a subnet mask of 255.255.255.0 would be 192.168.7.0. Remember that the subnet mask determines the network portion of the IP Address.
The subnet depends on the IP addresses of the computers you are trying to connect. In most instances, a subnet of 255.255.255.0 is sufficient enough to get the job done. Subnets only really need to be configured if you are trying to connect multiple network IP distribtuions.
When you set up a sub network you decide upon the subnet mask and this determines the network address (all zeros in the subnet portion of the address) and the broadcast address (all ones in the subnet portion of the address). When you assign the host addresses in your subnet, then you use the addresses between the network address and the broadcast address.
If a mainframe is using TCP/IP as its protocol it is configured the same way any other system using TCP/IP would be configured: an IP address, subnet mask, and default gateway address.
To determine the network or subnet address of an IP address
Depends on how you subnet it.
Since you haven't given a starting network address or subnet mask, impossible to say.
This is a network address
The subnet mask on host C is improperly configured.
Network Address, such as 192.168.1.0/24. Network Address is identified mainly by Subnet Mask.
