I have been requested to change the "Lease Expiration Option" from Permanent to Timed with an expiry date of 2030.

Just in my locations that I ma concerned of, I have over 10 subnets with pratically All IP's used.

Is there a way to make a Bulck change? I am currently doing it by hand, IP after IP.

I tried to change at Subnet header level, but it does not allow me to give more than 365 days. Doing by IP, I can enter the ending year.

Any ideas?

Thank you for your help and support.
