Nirvana | DNS outdated DNS was cool when speeds were slow and memory expensive. Now we could all run our very own DNS servers on the cheap. Why not?

1 edit | You could, but why would you want to increase the load on authoritative DNS servers out there? Right now, if you type in www.google.com, if you don't have the IP address already cached, your machine queries your ISP's DNS server, which already knows the correct IP address. Google's nameservers only get queried if your ISP doesn't have an IP address cached on their DNS servers. If everyone was running DNS, Google's servers are going to get hammered, since queries won't just be coming from a few thousand ISPs but from a few hundred million users.
Also, as hard as it is to patch DNS servers now, can you imagine if everyone was running DNS? Instead of patching a few thousand machines, you'd have to patch a few hundred million. |

Or you could just use OpenDNS, which, by the way, was secure the whole time.

well let's see, if the URL is not cached in your dns server, it has to ask for it in another server (not yours). if that server's record is incorrect, well guess what, yours will be incorrect.
i also don't really see the advantage of running your own DNS server for most people. sure it may be faster, but the dns retrieval is nearly nothing compared to the downloading of content and then processing. |

Right. Just run a local, caching DNS server that's configured to forward on to the ISP (or Open, or Level3) if it doesn't know the answer. No need for an end-user DNS to go straight to the authority, just up to the next link in the chain.
Mine currently forwards to OpenDNS for whatever it doesn't know.

| That is how DNS works.
If you have a DNS server and it does not have the answer it goes to the authoritive DNS server that is configured for it. It won't be going to Googles as mentioned above, it will eventually go to the root .com server which is what controls all .com DNS names. |
