A network-ready device is connected to a MikroTik RouterBOARD 750 with a functioning cable and is configured with 192.168.100.70/255.255.255.252. What is a valid IPv4 address for the RouterBOARD 750?

To determine a valid IPv4 address for the MikroTik RouterBOARD 750 when the device is configured with the address 192.168.100.70/255.255.255.252, it's essential to understand how subnetting works, particularly in this case.

The subnet mask 255.255.255.252 indicates that there are 2 usable addresses in this subnet. The notation "/30" confirms that 2 bits are available for host addresses, allowing for 4 total addresses, which are:

1. Network address

2. Usable IP address for one device

3. Usable IP address for another device (in this case, for the router)

4. Broadcast address

For the subnet defined by 192.168.100.70/255.255.255.252, the valid IP address range is from 192.168.100.68 to 192.168.100.71. Here, 192.168.100.68 serves as the network address, 192.168.100.69 is the usable address assigned to the router, 192.168.100.70 is assigned to the device, and 192.168.100.71 is the broadcast address.

Thus
