Is there a way to configure BIND so it answers for a zone, but only responds with the address of a different nameserver the client should ask? I set up a BIND instance on a VPS for adblocking purposes and it works fine (it’s ACL’d and not open to the public). Basically I set it … Read More “BIND: Redirecting queries for a zone to a different nameserver?” »

Is DNSCrypt and/or DNSSEC worth setting up? Once it’s set up, what’s the user experience like? Does everything work like it would if you didn’t use these two things and if a domain you’re connecting to doesn’t support it, will it simply not use it and connect normally? I was thinking of using it for … Read More “Is DNSCrypt and/or DNSSEC worth setting up?” »

I realize that this is a long shot but I want to give it a try. Does anyone have the com. and/or net. zone files for 2016-06-20?

Do you bother with a DNS caching server? Caching might already be done at the router level and is most likely done at the browser level–would setting up a simple DNS caching server on a Raspberry Pi be pointless, cause additional overhead, or is it actually something that produces noticeable (or even measurable) improvements? submitted … Read More “Do you bother with DNS caching?” »

If I want to compile a massive list of domains to block from other existing domains for blocking malware and ads, is it better to simply add them to the host file or use a DNS resolver such as dnsmasq that supports wildcards for performance reasons? I’ve heard that using a host file might be … Read More “Block lots of domains using hosts or DNS resolver?” »

I am having problems testing a app by using a local dns server to override the production server to a local dev server.
