Wfi and the broadcast IPs

Gordon Haverland

If a person has a wifi thing associated with a LAN, do sites via wifi
play by IP rules? For example, if I send a packet to, do
all (active) NIC on receive it?

What I am thinking, is for example:
<ARF-Temperature 16.3C/>
<ARF Time 16:42:03.4/>
<ARF Date 2020/04/13/>

An ethernet packet is 1500 bytes and has some overhead, but that block
of XML should fit in an ethernet packet (or similar wifi packets).
