Network is facts from the agent: what it believes its LAN and WAN are. A shared NAT address is shown as unknown — that is the hub's docker host, not the customer.
LAN IP, router, DNS and external IP come from the last heartbeat. When the external address has changed, the tile says since when and what it was — See when the external address changed. Under the tiles, each interface has its own receive and transmit — Read traffic on each interface. On a Teltonika or OpenWrt router the same tab shows backup mobile — Read backup mobile on a router. The neighbour table is Read devices found on the LAN. It does not enrol anything. New, missing and IP-changed rows are the interesting ones.
