DDWRT daemon.warn dnsmasq[1417]: ignoring nameserver 192.168.11.1 - local interface

See picture include

My dns like nanom2.dan.lan and nanom5.dan.lan and dan.lan not work

Your static DNS servers should be the upstream DNS servers on the internet that you'll be using for name resolution. Your router's local IP address is 192.168.11.1, so with the configuration in your screenshot, you're telling the router to look at itself for name resolution. What you really want is for the clients to look to the router for name resolution, while the router (using DNSMASQ) looks at a public DNS server on the internet, then provides those answers back to the client.

There are a number of good public DNS servers on the internet. I personally have been using Cloudflare (1.1.1.1 and 1.0.0.1). Other reasonable options include Google (8.8.8.8 and 8.8.4.4) or OpenDNS.

If you have "Automatic Configuration - DHCP" as your connection type, leaving the static DNS servers blank (0.0.0.0) will obtain DNS addresses from your ISP, which will work but may not be optimal.

I want that the client check first in dnsmasq of my router to see if there is an entry for this DNS resolution, if not then check on DNS public.

I want that dnsmasq keep 1500 DNS entry and I Try to configure my local name like dan.lan.

Actually when a client ask dan.lan it receive a Google search answer about dan.lan an I understand that not ask to my router dnsmasq. Same for nanom2.dan.lan and nanom5.dan.lan

I changed all static like you said 8.8.8.8 8.8.4.4 1.1.1.1.

I have same result. What’s now it’s not correct in my config?

See picture for

expand-hosts
address=/nanom5.dan.lan/192.168.101.1/

If the client ask Nanom5.dan.lan, for now it obtain googlesearch instead of 192.168.101.1

Try adding the following to your Additonal DNSMASQ Options:

dhcp-option=option:domain-name,dan.lan
dhcp-option=option:domain-search,dan.lan

Then restart DNSMASQ (killall -1 dnsmasq)

Release and renew DHCP on your clients. If you have static DNS suffix search strings on your client machines, add dan.lan. If you don't, because of the lines above, it should pick the suffix up from DHCP.

Hi,

I did all you show me. Check now the new config I have…. domain dan.lan doesn’t work.

Can’t resolv host dan.lan

Idea????

[ho1Aetoo]

You are using an old firmware build that is no longer supported.
Enable "local DNS" in the dnsmasq settings

[HHotline]

I’m trying but Don’t work….. other idea?

[dpp3530]

Going to ask a couple of stupid questions:

From the client side, check to see what DNS servers it's using (ipconfig /all on a Windows machine). If it's using anything other than 192.168.11.1, you obviously won't get the answer you're expecting.

Also, are the client machines using any kind of proxy server? If they are, is the proxy server itself using 192.168.11.1 as its DNS?

Not an expert on these matters, but if you set LAN Domain to dan, you also need local=/dan/ in the Additional Dnsmasq Options (at least with recent builds). Before I added that line, my local searches were first going to the upstream DNS servers before being resolved locally. (I caught this with tcpdump.)

Another fine point: local lookups seem to me to be case sensitive. I haven't checked this out carefully, but I have had lookups fail until I fixed the case.

Hi,

All clients have 192.168.11.1 as DNS

On other forum, someone said to me to In the Additional DNSMasq Options box, add "no-resolv" on a new line.

What do you thing about that?

Thanks all

is 192.168.1.12 only serving DNS names for dan.lan or does it forward to the internet for other domains?

If it only does dan.lan, then you can do something like this in Additional DNS config:
