A device connected to a MikroTik RouterBOARD 750 has an IPv4 address of 192.168.100.70 with a subnet mask of 255.255.255.252. What is a valid IPv4 address for the RouterBOARD 750 for a successful connection?

To establish a successful connection between the MikroTik RouterBOARD 750 and the device with the IPv4 address of 192.168.100.70 and a subnet mask of 255.255.255.252, it is important to understand how subnetting works with the specific subnet mask.

The subnet mask of 255.255.255.252 allows for a very small subnet, specifically only 4 IP addresses: one for the network address, two usable host addresses, and one for the broadcast address. For a subnet defined by the mask 255.255.255.252, the network address is the first IP in the range, and the broadcast address is the last.

Considering the device is assigned 192.168.100.70:

• The IP address 192.168.100.70 is the second usable IP address in a /30 subnet.

Given this, the valid IP addresses in this subnet would be:

• 192.168.100.68 (network address)

• 192.168.100.69 (first usable host address)

• 192.168.100.70 (second usable host address)

• 192.168.100.71 (broadcast address)

For a successful connection
