True, but all the same, a network admin is abrogating their responsibilities if
they don?t deal with the problem.
Yes, vendors ship stuff with ?interesting? defaults, but that?s not an excuse
to allow those stupid defaults to kill the network. Just think, if there were
half a dozen devices on a network all offering IPv4 DHCP services with rogue
parameters, I think you?d find the admins doing something about it PDQ. If they
can?t, or won?t, do the same for IPv6 then that suggests they are sabotaging
(whether by wilful choice or just plain disinterest) attempts to run an IPv6
network.
Just my 2d worth, Simon

Hi All,
I am trying to configure the dhcpd.conf to ignore the DHCP Release packet
using the ISC DHCP but facing issues, I can see we can do that using
Kea-DHCP
Reference link: https://kb.isc.org/docs/using-the-kea-dhcp-drop-class
If anyone has the same requirement and tried the case please let us know.
Any help/suggestion would be much appreciated.
Thanks in advance
