Does ArduinoMDNS update its mDNS cache automaticly? #5

Closed JulianS-Uni closed 5 years ago

JulianS-Uni commented 5 years ago

I am not that into mDNS but I read several times now that mDNS machines can update their mDNS cache automaticly.

When an mDNS client needs to resolve a host name, it sends an IP multicast query message that asks the host having that name to identify itself. That target machine then multicasts a message that includes its IP address. All machines in that subnet can then use that information to update their mDNS caches. Wikipedia

Does ArduinoMDNS library does this too or is it only possible to query for a host or a service which are both blocking operations?

Hi @JulianS-Uni,

The library currently only supports the second, it is "only possible to query for a host or a service which are both blocking operations".
