Question

Your DHCP servers are burdened with heavy traffic, most related to IP address renewals. Unfortunately, virtually all the IP addresses in each of your subnets are allocated. Which option is the best way to lower the renewal traffic?

Answer 1

To lower DHCP renewal traffic, increase DHCP lease time or consider DHCP load balancing, and if necessary, expand the subnet size.

Step-by-step explanation:

If your DHCP servers are experiencing heavy traffic due to IP address renewals and your subnets' IP allocations are nearly exhausted, an effective strategy to alleviate the load is to adjust the DHCP lease time. By increasing the default lease duration, devices will renew their IP addresses less frequently, reducing the number of renewal requests that your server processes. However, ensure that the lease time is balanced with the turnover of devices in your network to avoid running out of IP addresses. If expanding the lease time is not sufficient, consider implementing DHCP load balancing or increasing the subnet size to accommodate more IPs.
