Dnsmasq is a lightweight, easy to configure, DNS forwarder and DHCP server. It is designed to provide DNS and optionally, DHCP, to a small network. It can serve the names of local machines which are not in the global DNS.<\/p>\n

Basic DNS Setup
\nFirst things first, let’s install the package:<\/p>\n

\napt-get update\napt-get install dnsmasq\n<\/pre>\n
If your goal was to set up a simple DNS server, you just succeeded. To test it, use your favorite DNS lookup tool pointed at localhost:<\/p>\n
\ndig debian.org @localhost\n; <<>> DiG 9.16.33-Debian <<>> debian.org @localhost\n;; global options: +cmd\n;; Got answer:\n;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 23056\n;; flags: qr rd ra; QUERY: 1, ANSWER: 3, AUTHORITY: 0, ADDITIONAL: 1\n\n;; OPT PSEUDOSECTION:\n; EDNS: version: 0, flags:; udp: 4096\n;; QUESTION SECTION:\n;debian.org.

or<\/p>\n
\nnslookup debian.org localhost\nServer:         localhost\nAddress:        ::1#53\n\nNon-authoritative answer:\nName:   debian.org\nAddress: 128.31.0.62\nName:   debian.org\nAddress: 130.89.148.77\nName:   debian.org\nAddress: 149.20.4.15\nName:   debian.org\nAddress: 2001:67c:2564:a119::77\nName:   debian.org\nAddress: 2603:400a:ffff:bb8::801f:3e\nName:   debian.org\nAddress: 2001:4f8:1:c::15\n<\/pre>\n
By default, DNS is configured to forward all requests to your system’s default DNS settings. In case you didn’t know, these are stored in the \/etc\/resolv.conf<\/p>\n
To add names, simply add them to your \/etc\/hosts file.<\/p>\n
\nnano \/etc\/hosts\n192.168.0.155   ipgw.io \n<\/pre>\n
\ndig ipgw.io @localhost\n\n; <<>> DiG 9.16.33-Debian <<>> ipgw.io @localhost\n;; global options: +cmd\n;; Got answer:\n;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 53022\n;; flags: qr aa rd ra; QUERY: 1, ANSWER: 1, AUTHORITY: 0, ADDITIONAL: 1\n\n;; OPT PSEUDOSECTION:\n; EDNS: version: 0, flags:; udp: 4096\n;; QUESTION SECTION:\n;ipgw.io.

Choosing Your Interfaces
\nOne you will probably want to do is tell dnsmasq which ethernet interface it can and cannot listen on, as we really don’t want it listening on the internet. Around line 69 of the \/etc\/dnsmasq.conf file, you will see:<\/p>\n
\n#interface=\n<\/pre>\n
By default, DHCP is turned off. <\/p>\n
Now change your dns on the IPv4 to your dnsmasq address server and your DNS server like Cloudflare.<\/p>\n
