Hi everyone,
I m working for a small company that sells the Internet as an ISP.? One
of our clients calls every day about its IP address that is always the
same. Even though the client is on a dynamic pool, I think, when the
router automatically attempts to renew as soon as 50 percent of the
lease duration has expired, the DHCP server allocated the same IP.
Is there a command configuration in which I say change the IP address no
matter what? I mean, when the DHCP client tries to renew the IP address.
thank you for your time.
Best,
--

Your DHCP server is acting per spec. The ISC DHCP server does not have
an option to behave as you are asking as that would break the spec.
Does your customer want to have broken connections?
