1. Question:

What are the advantages of using a subnet mask?


A subnet mask allows for the division of an IP address into network and host portions. This division enables better management of IP addresses and helps in efficient routing of network traffic. The advantages of using a subnet mask include:

  • Improved network security: Subnetting allows for the creation of smaller network segments. By limiting the number of hosts in each subnet, it becomes easier to implement security measures and control access to resources.
  • Reduced network congestion: Breaking a large network into smaller subnets helps in managing network traffic and reducing congestion. This leads to better performance and reliability.
  • Simplified network management: Subnetting allows for logical division of a network into smaller subnets, making it easier to manage and troubleshoot individual segments.
