To accommodate a growing network, you might need to adjust your DHCP subnet size. Here are some recommendations:

1. Subnet Size Adjustment:
   • Use a /24 subnet (255.255.255.0) for 254 usable IP addresses.
   • A /23 subnet (255.255.254.0) offers 510 usable IP addresses.
   • For larger needs, consider a /22 subnet (255.255.252.0), which provides 1022 usable IP addresses.
2. Avoid Over-Allocating IPs: Ensure your DHCP lease time is appropriate to reclaim unused IP addresses promptly. Monitoring IP usage before expanding can help maintain efficiency.

By following these best practices, you can ensure that your network remains scalable and efficient.
