Jul 27, 2018 · A lot of people have questions about the concept of DNS Rebinding attacks, and many of the overviews dive too deep into the details. Here’s a simple explanation that should help those having trouble getting it.
Unlike BIND which can be used as both an authoritative and recursive name server, Unbound can only be used as a recursive name server. However, it has modules which support the DNSSEC feature. Just like BIND, Unbound was created for use on Unix-like operating systems. However, recent developments have allowed it to be used on Windows machines. PowerDNS

Jun 25, 2012 · Unbound doesn’t no anything about DHCP and it won’t accept DNS registrations from local machines. Dnsmasq does know about local names, since it’s the one handing out the IPs in the first place. Ideally, I use both DNS servers: unbound for external queries and dnsmasq for internal (and internal only!) queries.
Wed, 20 May 2020 21:16:12 GMT Fri, 12 Jun 2020 18:08:46 GMT <p> In order to configure dnsmasq to act as cache for the host on which it is running, put "nameserver 127.0.0.1" in /etc/resolv.conf to force local processes to send queries to dnsmasq.

EdgeOS includes a DNS forwarding service based on dnsmasq that is consulted when clients use the EdgeRouter as a DNS server. The dnsmasq service runs in the background and will forward all client DNS queries to the specified DNS server(s). There are two methods that can be used to provide DNS services to clients:

Jan 03, 2020 · DNSSEC and DNS over TLS are security enhancements Quad9 offers that many other DNS providers do not. DNS over TLS, for example, forces your pfSense firewall (unbound resolver) to encrypt the DNS transaction as it traverses the internet; what that means is a man-in-the-middle on the internet (or a nosy upstream network provider) can’t see which hostnames you are querying and as important, no ...
There are many ways to use Dnsmasq and /etc/resolv.conf together. My preference is to enter only 127.0.0.1 in /etc/resolv.conf, and enter all upstream nameservers in /etc/dnsmasq.conf. You don’t need to touch any client configurations because Dnsmasq will provide all network information to them via DHCP. Local DHCP
I'm running a local server with dnsmasq and unbound. The unbound is listening on 127.0.0.1:5300 on the server network.local. The dnsmasq is listening to 0.0.0.0:53 and has a config line stating server=127.0.0.1#5300. If I, on the server, query unbound directly, I will get the same answer everytime (with changed TTL's due to caching). This ...

Dnsmasq (whether I use an upstream DNS or unbound) gives me control over how stuff is looked up. For example, when I was working on a new web site, I could tell dnsmasq to use the hosting company's DNS for that one domain, so I did not have to wait for caches to expire between me and the host. Dnsmasq caches lookups. Actually, unbound does, too.
Unbound is a full DNS resolver with support for DNSSEC (signed DNS requests). If you want a "full and complete" DNS cache, install that instead of using dnsmasq (which comes by default). NOTE: There is one thing to be aware of when using Unbound.

With the move from bind to unbound, it is no longer possible to block ads through /etc/hosts. So I decided to try making a URL Filter called "mvps_hosts" (the hosts file I use to block ads). I downloaded the latest hosts file and stripped out everything but the urls, then pasted it into my custom URL Filter I made. I prefer taking all the resolver-breakers out. there's usually not more than 2-3 legit resolver updates in 5 years of lifetime of 10000s of servers but guys keep optimizing for a laptop. doesn't matter to them if companies lose millions due to prolonged outages caused by this stuff, and the impact on safety-critical systems is just waved away by "those people will test/optimize it anyway". yup ... dnsmasq is so tightly integrated in the firmware, doing a firmware 'replace' is likely not to be easy. The only easy way I can think of is to specify the unbound server on the LAN page and disable the option to pass the router address so only the unbound server is passed to the clients for their DNS.
