Ramhound : DNSSEC is certainly not a "replacement" for DNS, it is an extension of it.

comment Where did this incorrect cached DNS lookup come from?
Very hard to suggest any possible reason without the real domain name... dougbarton.us/DNS/bind-users-FAQ.html#RealNames

comment Strange DNS problem [seems to be IPv6 issue]
Very bad advise to disable IPv6 less than two years before the end of IPv4 addresses...

Bad advice, like many things coming from Bernstein (who said a lot of stupid things about the DNS).

comment How to choose a sensible local domain name for a home network?
Very bad advice since 1) They could be created by ICANN later and 2) your organization may merge with another one which already uses it

By curiosity, why using the lying DNS resolvers of OpenDNS ?

comment Name reputable dns servers for home use (as alternatives to your ISP's)
Do note that such "open" recursive name servers are typically a bad idea, as explained in RFC 5358 "Preventing Use of Recursive Nameservers in Reflector Attacks"

comment Name reputable dns servers for home use (as alternatives to your ISP's)
Warning, you make a big confusion between lying DNS resolvers (Comcast, OpenDNS, etc) and 404 errors which are a HTTP feature, completely unrelated.

comment Running DNS locally for home network
Be careful that OpenDNS name servers are liars: they rewrite DNS responses, to direct you to an ad service or to censor some destinations.

comment How ADSL connections work through router
Note also that it is specific to IPv4. With IPv6, there are much more IP addresses and therefore no need for the NAT hack.

comment Rename a group of files with one command
No, it works (I ALWAYS test before posting on SuperUser). The need to escape # depends on the shell you use (I use zsh).

comment How can I set up Linux to use a different DNS server for a certain domain?
That would be a poor solution because this information will quickly become stale. Never put in a static file data which is outside of your control.

comment Can't resolve domain names in Ubuntu with a static IP
Bad idea, they are lying DNS resolvers, which modify the legitimate responses (for instance to direct you to advertisments).

comment DNS does not resolve
Better to indicate the actual domain name. Otherwise, we can only guess.
