Yeah, there's a lot going on in ppp systems.

I don't do dialup anymore. But, looking at my old PPP setup (I'm
surprised I still have it), 'dns-addr' is assigned in /etc/ppp/options.

Maybe you could try sneakernet.
They're in sealed boxes, up high, possibly near high-voltage equipment.

This is absolutely not the case. Never attribute to malice that which can
be more easily explained by massive bureaucracy. Also, these are devices
that are on a network that couldn't
Ah, they want you to debug for them for free. If the client is big
enough, then, yes, do complimentary service. If not, then just upload
an encrypted zipfile to OneDrive (or whatever), and tell them to download.

If the externally-reachable network is intended for the IOT devices to connect to, they may well be
using IP addresses only. Call it the "DMZ network" or "external network".
They probably have a "management network" that goes to different interfaces,
and which has DNS services for their own
You can enable debugging in your pppd config which may help.
There is also a "usepeerdns" pppd option that may give you some joy.
I have a client who has a prison as a customer and they have lots of
unusual requirements for computers inside the wire.
I have debugged hundreds of PPP
Thanks, all. Yes, there has to be a DNS, but there's a chance that
1. we haven't been told what it is;
2. our connection/hardware hasn't been authorized to connect to it or
know what it is
(yes, it's that kind of place)
There is no other internet connection. We've been given a host
PPP does not require a dns server address to be provided.
But most folks do provide one because it would make for LOTS of support
calls to not hand out your DNS servers.
Is there a DNS on the network that your connecting to at all?
If not then you wll likely be forecd to use the /etc/hosts
How do they want you to find things on their net?
Do they have a DNS server? Surely yes.
They should put it into the PPP negotiation. Why would they not?
If they won't put it into PPP, maybe you have to monkey with
/etc/resolv.conf (systemd will argue with you).
If they don't have a DNS,
I wonder if
1. they decided to not use DNS, in which case they would have given you an IP
address, or
2. they decided to not tell outsiders where the DNS server was, so that the
outsider would have to be given an IP address, or
3. they didn't tell outsiders where the DNS server was

I'd have expected so, but that RFC says "By default, no primary DNS address
is provided."
