Do you have old and new connection settings saved? If so, and you want to keep both saved, you could reduce the *priority* of the old static one. Otherwise, delete the old configuration. When a client tries to connect to a LAN, it *may* request to use its prior IP, but the DHCP server does not have to concede. The client *should* use what the DHCP server tells it to use (which may be the same as before, or different even if the lease time is still valid). You *may* not have to accept DHCP configuration, even if the router is issuing them. Here, I can certainly use a fixed IP with a router doing DHCP (as long as there aren't clashes with other equipment on the LAN). I limit the IP range of the DHCP server, and deliberately set manual IPs outside of its range. But I can forcefully set an IP that is within the DHCP server's allocation range. Though it's up to me to deal with the consequences. Other routers *could* configure various things (e.g. firewall) to only allow the IPs they've allocated, so you may *need* to let *them* be in control. -- uname -rsvp Linux 3.10.0-1160.119.1.el7.x86_64 #1 SMP Tue Jun 4 14:43:51 UTC 2024 x86_64 (yes, this is the output from uname for this PC when I posted) Boilerplate: All unexpected mail to my mailbox is automatically deleted.
