I'm new to the Archer A7, and didn't realize it doesn't have a full DNS server included. It forwards my requests externally just fine, but does not resolve dhcp IPs.
How do others deal with this?
My thinking is to stick dnsmasq on a VM; will the Archer DHCP server update the DNS server, assuming I point it to the DNS server?
Thanks,
Dave

DNS addresses can be setup in 3 different locations. WAN, DHCP Server and Dynamic DNS. Since you mentioned that the router is not resolving DHCP addresses I would ask to know how your DHCP Server section Advanced > Network > DHCP server is configured

Thanks very much for your reply!
WAN is setup as DHCP, so pulling IP, DNS from Verizon.
I have not configured Dynamic DNS, but may do so in order for my domain name to resolve to my correct IP. Verizon doesn't change IPs on me all that often, so that isn't a high priority for me.
Regardless, both of those are external resolution, and not what my issue is.
My DHCP is set for my router's LAN IP--192.168.2.1--to be the primary DNS.
But when I run 'nslookup desktop' on my desktop machine, it doesn't resolve to the DHCP IP number of my Windows desktop (named: "desktop")
...snip...
C:\Users\davegold>nslookup desktop
Server: UnKnown
Address: 192.168.2.1
*** UnKnown can't find desktop: Non-existent domain
...snip...
So my guess is that while it listens on the DNS port, and that will work as a DNS forwarder, there is no connection between DHCP and the internal DNS proxy.
Thus my question on how others work around this, other than reserved dhcp IPs and hosts files, that is.
Thanks,
Dave

That should be working then. Let me reach out to my system engineers and see what they recommend. I'll reply once I have an answer.

@Carl I am also experiencing the same issue, DNS will not resolve with the IP of a device with a DHCP lease

What does your DHCP server screen look like? Particularly what are your DNS addresses set to?

Firmware Version 1.2.0 Build 20211210 rel.56314(5553) Hardware Version:Archer A7 v5.0
And if i tried to ping my devices on my network the name will not resolve to an IP i get this:
"Ping request could not find host DesktopName. Please check the name and try again."

Okay for your case in particular I would recommend using public DNS addresses. the two I would recommend using are either Google or OpenDNS.
Google:
Primary: 8.8.8.8
Secondary: 8.8.4.4
OpenDNS:
Primary:208.67.222.222
Secondary: 208.67.220.220
If this doesn't help let me know.

You would have to have a DNS server setup on you network that all your clients talk to in order for you to achieve your goal. Your DNS server would then have to subscribe to a public server for updates needed for public name resolution. I am familiar with DNSmasq for it's DHCP services, but I would reccomend some googling on using it in your use case.
