[Dnsmasq-discuss] Some clients get wrong IP

[richardvoigt at gmail.com]

Check your log, see if the camera is reporting a wrong MAC, different
client-id, different vendor class, or something like that.

Or possibly the camera's bootloader is remembering its old address
(gotten before you configured your hosts file) and requesting a
renewal.  Again, the log would show a renewal request.
