 What is IP Subnetting?


IP subnetting is a process of dividing a larger network into smaller subnetworks to improve network performance, security, and address allocation efficiency. It involves using a subnet mask to determine which portion of an IP address identifies the network and which portion identifies the host.To solve the given problem:

1. Identify the network address:

The IP address is 10.35.154.117, and the subnet mask is 255.240.0.0.

2. Convert the subnet mask to binary:

255.240.0.0 = 11111111.11110000.00000000.00000000

3. Determine the network and host portions:

The first 12 bits (11111111.1111) represent the network, and the remaining 20 bits are for hosts.

4. Calculate the network address:

10.35.154.117 AND 255.240.0.0 = 10.32.0.0

5. Find the broadcast address:

The broadcast address will have all host bits set to 1.

10.47.255.255

6. Determine the last valid host:

The last valid host is one address before the broadcast address

Therefore, the last valid host on the network that 10.35.154.117 255.240.0.0 is a part of is:10.47.255.254

This address represents the highest usable IP address in the subnet before the broadcast address

To increase the attachment file size limit in Exchange Server 2019

  https://www.youtube.com/watch?v=9hLxvwO1VCs&t=4s To increase the attachment file size limit in Exchange Server 2019 To increase the attachment file size limit in Exchange Server 2019, you can follow these steps: Check current limits: First, verify the current message size limits by running the following command in the Exchange Management Shell: Powershell Get-TransportConfig | Format-List MaxReceiveSize,MaxSendSize Increase the limits: Use the Set-TransportConfig cmdlet to increase both the MaxSendSize and MaxReceiveSize. For example, to set the limit to 50 MB: powershell Set-TransportConfig -MaxSendSize 50MB -MaxReceiveSize 50MB Note that you should set the limit about 33% higher than the actual desired attachment size to account for Base64 encoding. So for a 50 MB attachment limit, you may want to set it to around 67 MB. Restart Exchange services: For the changes to take effect immediately, restart the Exchange services using: powershell Get-Service *Exchange* | Where {$_.D...
