[Kea-users] kea hands out 2 ip addresses

Hi, keadhcp is currently handing out 2 ip addresses to each client
unnecessarily in short succession.  It hands out the first ip address, it
then replaces the first ip address with a second one a few seconds later and
then eventually expires the lease on the first ip address.  Please note the
short lease time is for testing and this issue occurs when the lease is set
to an hour also.

This also occurs to clients that are windows and linux based so I am pretty
sure my client settings are not the issue either.

My expected behaviour is that keadhcp hands out a single ip address to a
client.

My client has 1 interface 

1) client spins up 
2) requests ip address 
3) kea supplies ipaddress 
4) keaddns then hands off dns name to powerdns 
5) client then requests another ip address 
6) kea supplies 2nd ip address, this then replaces the first ip address and
dns name on the client 
7) kea then hands off 2nd dns name to powerdns. 
8) lease expires on 1st ip address and is reclaimed by kea and removed from
powerdns.

here are my logs, here you can see a client ends up requesting 2 ips in a
short space of time.
