The time to live for the advertisement is measured in hops (steps) for each UPnP
packet sent. Hops are the steps a packet takes between routers. The number of hops
can range from 1 to 255. The default value for the advertisement time to live is 4
hops, which should be fine for most home networks. If you notice that some devices
are not being updated or reached correctly, it might be necessary to increase this
value.

active for each IP address.
