A network engineer must configure an interface with IP address 10.10.10.145 and a subnet mask equivalent to 11111111.11111111.11111111.11111000. Which subnet mask must the engineer use?
The subnet mask equivalent to 11111111.11111111.11111111.11111000 in dotted decimal notation is 255.255.255.248.
To determine the appropriate subnet mask for the given IP address and subnet mask, we need to identify the number of bits in the network portion of the address.
In this case, the first 29 bits of the IP address are used for the network portion, and the remaining 3 bits are used for the host portion. Therefore, the correct subnet mask is /29.
