Greetings. I've read posts that come near to answering this question, but not quite.
I'd like to map two (or more?) MACs to the same IP address and hostname. In my case, it's because I have two NICs in my (Linux) laptop, and I want to treat the laptop as the same machine regardless of which NIC is in use. Right now I've got NIC 1 (eth) set to DHCP assigned via FTL (5.7) in Pi-hole, with NIC 2 (usb) configured with a static IP at the laptop. That's a workaround, but it seems less than ideal.
The Pi-hole web interface blocks an attempt to create a duplicate lease, and hand-editing 04-pihole-static-dhpc.conf proved to be ... a bad decision. I don't want to blow up my system again, so I'm wondering if there's a way to implement (outside the interface):
I found the above in a dnsmasq discussion, with the claim that dnsmasq will release a valid, unexpired, in-use lease using this syntax in its configuration file.
Any help appreciated,
