dnsmasq stores its currently active lease information in a file
(dnsmasq.leases), see

https://dnsmasq.org/docs/dnsmasq-man.html#lbAL


An explanation of the field format can be found from the mailing list, see

And of course, if you knew either an IP or a hostname of an active(!)
dynamic client, you could query dnsmasq for the other.

Kind regards,
