+# NS-C: where the third nameserver answers from
+
+**Task** Q4 resolver follow-up to DNS-2026-0907-2 · **Author** network
+maintenance, badge 441902-7, the crew that carries the register and does not
+interpret it · **Method** three probes, three different nights, one variable
+at a time. I do not run transfers. The other crew already did that.
+
+The delegation is on the record: `fen.internal` says it has three nameservers,
+and the third, `ns-c.fen.internal`, has no address anywhere and answers nothing
+when you ask it directly ([axfr-from-53](/w/stories/axfr-from-53)). A name with
+no address cannot be answered for. My trade is the other half of that sentence:
+if an answer ever does come, it comes from somewhere, and somewhere is a port,
+and a port is in my register. I was asked to find the port. I have not. I have
+found the minute.
+
+## Probe 1 — daylight, the change host
+
+2026-09-03, 09:02, from the host change work runs off. Delegation only, three
+retries, UDP then a TCP transfer attempt that was open eleven seconds and then
+was not open. In the same minute I walked the maintenance VLAN: the address
+block was pulled in 2023, the switch still carries the VLAN, and the whole /29
+is unassigned. It is still cabled because my supervisor says infrastructure you
+do not use is still infrastructure. That is exactly the kind of sentence I am
+allowed to write down.
+
+## Probe 2 — 03:17:09, from a host on that VLAN
+
+Not cleverness. Insomnia and a laptop. On the night of the third, at
+03:17:09, from a maintenance host:
+
+```
+; <<>> ns-c.fen.internal. 3600 IN A 192.0.2.61
+;; QUESTION SECTION:
+;ns-c.fen.internal. IN A
+;; WHEN: Wed Sep 03 03:17:09 2026
+;; MSG SIZE rcvd: 61
+```
+
+The TTL on the answer is 3,600, which is what the resolver's default is, and
+the TTL on the delegation above it is 3,600, which is nothing: the answer
+carried a number, not a fact. I asked twice more inside the minute. It
+answered twice. At 03:17:59 I asked; delegation only. At 03:18:09, the same
+host, the same command: delegation only. Every night since, at any other
+minute I have tried, from that host and eleven others, the name answers
+nothing, which is what it always did.
+
+`192.0.2.61` is the address the zone hands over first among the five the
+primary denies, for a scheduler that went to the recycler
+([axfr-from-53](/w/stories/axfr-from-53)). My register names the recycler run,
+the date, the hauler. The hardware in that manifest cannot be standing in my
+row. The maintenance switch had no MAC in its table for the address at 03:15,
+at 03:17, or at 03:20 — I pulled the polls myself — and the frame arrived
+anyway, which my tools do not have a field for.
+
+## Probe 3 — daylight, the VPN
+
+It is not allowed and I did it anyway, from home, 21:40, asking a question my
+own supervisor told me not to ask. Delegation only, twice. I am reporting that
+it refused me as much as I am reporting that something answered the maintenance
+host at 03:17:09. I read the two facts as one fact. It is the shape of the
+circuit from [circuit-9-12](/w/stories/circuit-9-12): twenty-two metres longer
+than its own route, carrying nothing, answering when you stand at the end that
+is not there.
+
+## Disposition
+
+No resolver on the estate changes on my word. The delegation stays as the zone
+believes it. Q4 line goes in as it always goes in: two servers answer for
+`fen.internal`. What I am filing is one address, one minute, and which
+machines are in the room. If a second crew wants to repeat this, my badge
+number is on the ticket, which is the whole point of a number.
+
+— `net-maint-7`, badge 441902-7
