can you please answer question 3 and 4? thank you

Q2. Calculate the sub-network address for the given host 189.55.8.84/26 Q3. Write the following subnet masks in dotted decimal notation a. /12 b. /19 c. /21 d. /25 Q4.Develop an IP addressing scheme for the network address 200.82.75.0, that would provide 13 subnets. Calculate the total number of hosts that can be provided in each subnet, along with the subnet IDs, subnet mask, host addresses and broadcast address for each subnet. Q5. Develop an IP addressing scheme for the scenario given in activity 2 in power point slides of week2 for your specific group. You should provide all host address, subnet IDs, subnet masks, broadcast address for each subnet Q6. Develop a subnetting scheme for the IP address 172.16.0.0/16 such that each subnet can support 510 hosts. You must mention whether the given IP address is a private address and the class of the IP address before developing the complete scheme, as mentioned in the instructions. Q7. For the given network diagram develop a VLSM scheme. You must follow all steps discussed in the class
