... I mistakenly sent this to the dhcp-worker mailing list initially.
better match for this list.

I'm assessing the IP locking feature available on arista eos devices:

https://www.arista.com/en/support/toi/eos-4-23-0f/14355-ip-locking-release-updates

Works well on a strictly dynamic pool however as the support doc
states, it doesn't work with hosts designated with a fixed-address.  

Is there any config at my disposal to get around this problem?  

The arista doc says to use "Use reserved leases instead.".  I am not
seeing any information on this from ISC or Arista.

Anyone else have experience with this?

- Jason

Hi Jason,

The issue there is that ISC DHCP does not create a lease when the
fixed-address keyword is used.  Therefore, there is no lease to query.
To get around that (comes with other side effects such as a new client
device cannot be assigned the static address until the lease expires),
you would want to not use the fixed-address keyword.  You can reserve
an address by creating a class that matches the client and then
creating a small pool of only one address that allows members of that
client's class.

Thank you,

Darren Ankney
