From the instance with bind running, can you query both your defined
forwarders? Does it work consistently for a variety of domains?
dig @1.1.1.1 isc.org
dig @8.8.8.8 isc.org
Yes, it does. The above two commands work as well as several other
domains I tried, and the response has been immediate.
From the clients can you use nslookup or dig to query the bind instance
directly by specifying the ip and get consistent resolution from it for
different names?
Yes. From my Windows 7 desktop client I use the "Command Prompt" with
"nslookup" and get perfect and immediate results by specifying my DNS
server's hard IP. Furthermore, I ran the same command with no server
specified and it defaulted to my server's BIND instance and gave the
same immediate results. Unfortunately, I do not have "dig" on my
Windows7 clients.
Have you validated the DNS server IPs that are assigned to the clients
have the correct IP(s) set for the bind server?
Yes, they all do. They are set to the machine's IP on which the DNS
instance is running.
Are you sure there is only 1 dhcp service active on the network? Is the
WAP doing dhcp as well and giving conflicting options maybe?
Yes, there is only one (1). The WAP is not capable of performing DHCP
service. It only passes through requests to the DHCP server on my
machine. I can verify this by examining the list of active leases on my
DHCP server.

Is the browser using the OS settings for dns, or are they trying to do
DNS over https directly out to the Internet to other dns servers?

Howdy all!. My name is Arnold, and I'm new to both Bind9 and to the
Bind user's list. I'm hoping to contribute my findings on the use of
Bind9. in the future but, for now, I need some help in getting my 1st
install of Bind 9.18 performing well. It does run already, but does
not perform well at all. I'll explain.
First, a quick bit of history. I run a home network (a full domain
structure) and, for the past 23 years, I ran a server (Windows Server
2003) as a full Primary Domain Controller in my home network. I ran
DHCP, DNS and AD on that server. It worked great and had extremely
fast responses for DNS forwarding. Very rarely was there ever a
failure (i.e. "Site not found" or "No Internet Access") etc. And it
ran great for almost 23 years.... Until this past Easter Sunday, when
it died a nasty hardware death. I deemed it unworthy of repairing.
This because, 2 years ago, I began building two new mid-tower machines
(Intel coreI7 and was going to install Ubuntu Server (22.04) on one
and the 22.04 client on the other. I completed the client machine and
it is up and running perfectly. I held off on the server as my Win2003
server was still running. But not anymore.
I resumed the build of the Ubuntu Server (22.04). I installed
ISC-DHCP-Server for DHCP (I know Kea is available but I read where
that needs Ubuntu 24.xx+). I also installed Bind9.18 as the DNS
server. The DHCP server is working perfectly. No issues at all. Very
happy with it. The Bind9.18, not so much. BTW, I'll deal with an AD
replacement later if at all (Samba, Kerberos or something similar).
The following are the behavioral symptoms of the current Bind9.18
install.
* Links/URLs - Links/URLs submitted in a browser (especially a link
not used before or not after a long while) often take a very long time
to render and often fail with a "Can't access that site" or "No
Internet Access" error. if I keep refreshing the same link/URL
multiple times, eventually the webpage will render correctly. And the
site will continue to render correctly as long as I keep it active by
clicking other links, etc. on the page. But once there has been a
period of inactivity (usually 1/2 to 1 hr), it goes back to the
original behavior, requiring another cycle of "refreshes" and "site
not found" errors, before it renders correctly again. That said, I'm
starting to see continuity on the URLs/Links I use on a daily basis
(i.e. only once a day).
* When using "ping," if I ping the hard IP, it works correctly. If I
use the domain name with Ping, it fails on a "name resolution" error.
However, using "nslookup" with the same domain names does work
correctly. Cannot use traceroute as it is not presently installed and
attempting to install it gives "Temporary failure resolving the ubuntu
archive DBs.
* Devices that had connected to my Wireless access point (WAP) that
are "DNS dependent" also fail due to "No Internet access," including
my smartphone in Wifi Mode. My phone does not fail when in "5G" mode,
but that's expensive. FTR, my router is "wired" but I have a WAP
connected to it via Ethernet. Devices that connect to it can get DHCP
service, but fail when DNS is attempted. My laptops do not connect via
WiFi anymore. I can get one of my laptops connected if I 'Tether" it
to my smartphone while in "5G" mode.
All of the above leads me to believe that Bind 9 may not be configured
correctly to allow for the best possible performance/response times by
the forwarding servers (8.8.8.8 and 1.1.1.1). I have attached my
named.conf.options file and .local file. The named.conf file only has
includes for .options and ,local conf files. The .default-zones file
is commented out.
If you need other info about my configuration and setup, please feel
free to ask and I'll do my best to provide it.
Thank you all so much and I look forward to learning from you.
Regards,
Arnold
