In the Android example above, the numbers are stacked vertically on the left.
The top number is the IP address with the most relevant digits conveniently highlighted in yellow. The bottom number is the MAC address*, a (presumably) unique number assigned to every Ethernet network adapter, both wired and wireless.
For the first couple days I was using Fing, there was a device on my network that I could not identify. The network adapter was made Hon Hai Precision Ind. Co., Ltd which was no help at all. Turned out be a Vonage box, stuck in a corner; out of sight, out of mind.
The other text describing a device on the network is, for lack of a better term, the computer name. In my tests, this was all over the map.
