[Kea-users] Is Kea-DHCP able to support a /30 network?
In one of my subnets I am having to deploy, I have a /30 network which has only one IP. Will Kea-DHCP be able to support this, as I have not seen anything in the documentation for this. If so, would I have to set up the Pool to look like... "subnet": "10.10.1.0/30", "pools": [ { "pool": 10.10.1.2 } ], Or would it have to look like... "subnet": "10.10.1.0/30", "pools": [ { "pool": 10.10.1.2 - 10.10.1.2 } ], Thanks, Scott -- ISC funds the development of this software with paid support subscriptions.

[Kea-users] Lease Tuning
I have started the implementation of what could become a large number of users/pools in a Kea-DHCP4 (20 pools/5000+ IP's) and have some questions about how to estimate/calculate some of these values. How do I determine how long it takes to clean the memfile database? What is the best way to calculate the lfc-interval and reclaim-timer-wait-time? Is it based on the predicted number of IP's that could/can be used? Are there advantages/disadvantages to having a short or long interval/timer? Are the valid-lifetime, T1, and T2 values part of how to calculate these values? Thanks Scott Rakow -- ISC funds the development of this software with paid support subscriptions.

[Kea-users] Upper End Bounds
All, A few questions on the upper end bounds for Kea-DHCP4 - At what point would you move from the memfile and go to a database? - How many pools would the server be able to handle without breaking? - And what if they are all going through the same NIC (relayed from routers)? Right now I am looking at about 20 pools ranging from /27 to /22 subnets to bring into Kea and need to know how far I can push it.

Re: [Kea-users] Lease Reclamation
Darren, Thanks for the reply. I guess I should restate my question a bit better. If both of the "max-reclaim-leases" and "max-reclaim-time" are zero, from what I read in the documentation, the number of leases that will be claimed is unlimited and the time to reclaim them is unlimited. If the reclaim time is unlimited how does the system know that that cycle has ended, as if it is unlimited, the cycle should keep going (which would be bad, as no IP's would be given out). Is there a counter/timer that if all is set to "unlimited" and if nothing is reclaimed in X time, it ends the cycle and the wait-timer can take over?

[Kea-users] Lease Reclamation
I have a question when setting "max-reclaim-leases" and "max-reclaim-time" to zero. If both are unlimited, when would the reclaim time end and the "reclaim-timer-wait-time" be able to enact its buffer? Would not the reclamation cycle be continuous, as there is no end to the max-reclaim-time? Scott -- ISC funds the development of this software with paid support subscriptions.

[Kea-users] Stork for RedHat/Rocky 9?
In wanting to install and test the latest version of Stork, the RPM's look to only be for RedHat/Rocky 8. Will the next version include a build that will work on 9?

[Kea-users] exclude command?
I have searched the documentation and could not find a reference to this, so I thought I would throw this out there, Is there an option command exclude-ip or exclude-address for dhcp4?

[Kea-users] Memfile vs Database
Kea hive mind, I am looking to use the DHCP server in hot standby HA configuration that will be using about 4,000 IP’s across 20 pools. I will be using options and perhaps later I may have to include reservations. At what point do I look at using Kea in a database configuration instead of the memfile configuration?
