Q&A: What is the DHCP leasetime

Question:

What is the DHCP leasetime?

Answer:

You can define a policy, which sets the prefered leasetime.
Check with

:~# udm policies/dhcp_leasetime list
or 
:~# univention-ldapsearch univentionDhcpLeaseTimeDefault=* dn
If you have no lease time defined, the default leasetime of the dhcp.conf is used.

man dhcp.conf
default-lease-time time;
Time should be the length in seconds that will be assigned to a lease if the client requesting the lease does not ask for a specific expiration time. This is used for both
DHCPv4 and DHCPv6 leases (it is also known as the “valid lifetime” in DHCPv6). The default is 43200 seconds.
