The node's log names the host addresses it put in its answer.

It is the first thing read when a member reports "DataChannel closed", and it
read `host: none` for every answer: the match wanted `" typ host "` with a space
after it, and aiortc ends a host candidate line at `typ host`. The addresses
below are the test node's of 2026-10-16.
