This option doesn't allow block-list optimization (by removing secondary level domains if the top-level domain is also in the block-list), so it results in a much larger block-list file, but, unlike other DNSMASQ-based options, it has almost no effect on the DNS look up speed.

This option allows the block-list optimization (by removing secondary level domains if the top-level domain is also in the block-list), resulting in the smaller block-list file. This option will slow down DNS look up speed somewhat.|
 |```dnsmasq.ipset```|Creates the DNSMASQ ipset file ```/var/dnsmasq.d/simple-adblock.ipset``` and the firewall rule to reject the matching requests. This is the only option for AdBlocking if you're using a browser with [DNS-over-HTTPS proxy](https://en.wikipedia.org/wiki/DNS_over_HTTPS) built-in, like [Mozilla Firefox](https://support.mozilla.org/en-US/kb/firefox-dns-over-https#w_about-dns-over-https) or [Google Chrome/Chromium](https://blog.chromium.org/2019/09/experimenting-with-same-provider-dns.html). This option allows the block-list optimization (by removing secondary level domains if the top-level domain is also in the block-list), resulting in the smaller block-list file. This option requires you install ```dnsmasq-full``` and ```ipset``` [as described here](#how-to-use-dnsmasq-ipset).<br/>PLEASE NOTE, that unlike other options which are truly domain name based blocking, this is essentially an IP address based blocking, ie: if you try to block ```google-analytics.com``` with this option, it may also block/break things like YouTube, Hangouts and other Google services if they share IP address(es) with ```google-analytics.com```.|

       - Stopping/removing/disabling DNS-over-TLS, DNS-over-HTTPS or DNSCrypt on your local device and using the secure DNS on your router instead. There are merits to all three of the options above, I can recommend the ```https_dns_proxy``` and ```luci-app-https_dns_proxy``` packages for enabling DNS-over-HTTPS on your router.
