DHCP Best Practice
Hello,
My DHCP scope server is over 90% full
I do not know which solution is better:
Solution 1: Change allocation time of DHCP leases from 8 days (default) to 4 days (or 1 day)
Solution 2: Add a second DHCP server, in the same network, with a different scope
(for example : server-dhcp-1 from 192.168.1.50 to 192.168.1.100 and serveur-dhcp-2 from 192.168.1.150 to 192.168.1.200)
Are both solutions OK, or one solution is better and recommended?
Thank you

Changing the lease time won't help if you regularly have enough clients to consume 80% of your address space. If that's the case, adding another scope is best.
Best to change the lease time to one day first. If you are still getting dhcp to 90%, change the scope of the DCHP server to 192.168.1.50 to 192.168.1.200 and get a Exclusion Range in DHCP from 192.168.1.101 to 192.168.1.149.
I would not recommended having two dhcp server unless you prefer redundancy.

Oh, and if you're only using 50 addresses in your current scope, it would be easier to just expand the scope to include more addresses in the current address space...unless you are crowded above and below by other address blocks (e.g. go from 192.168.1.50-100 to 192.168.1.50-150.
Regardless, there is no downside to adding another subnet other that to make it a bit more challenging to manage.

I will test this solution, since there are many Iphone and Android using the scope. THank you
... and adding DHCP servers isn't a good way in increase the DHCP scope. re: Solution 2.
An extra consideration: On Windows servers I'll set the scope to .1-.254 (on a /24 subnet) but then add excluded ranges within that. You can change what ranges are excluded but you can't change the scope without recreating it.
