Hello All,
I would like to know, what is the best lease time for DHCP for company which has 10000 users. Is the default one a good one. I know clients will start renewing after 50% of time. Please advise.
Thanks

Hi,
>>Is the default one a good one
It's up to you.
Based on my knowledge, when 50 percent of the lease duration has expired, the DHCP client automatically attempts to renew its lease from the DHCP server which the client obtained the lease. If fails, the DHCP client broadcasts a DHCPDISCOVER packet to update its lease when 87.5 percent of the lease duration expires.
You can adjust the lease to meet your needs.
In general, if you are in a large network or have enough IP addresses in the **DHCP **scope for clients, you can increase the lease duration to reduce network traffic.
If you have a limited number of IP addresses available, you may need to reduce the lease duration. Although reducing the lease duration creates more DHCP-related network traffic, it increases the rate at which addresses are returned to the available address pool for reassignment.
