I hosted my own DNS server using my NAS, and you can too

Everyone wants to improve their internet speed, whether by boosting their Wi-Fi performance or switching to fiber-to-the-home. Those are good ideas for straight-line download speeds, but to make your browsing feel snappier for every website you visit, there's only one (almost) guaranteed fix. That's to self-host your own DNS server. Your devices sending DNS lookups to something on your home network are an order of magnitude faster than sending those same requests to an external DNS server and waiting for the reply.
