Why I Use My Own DNS Resolvers

For those of you who do care, but don’t know, DNS is what translate domain names into IP addresses and vice versa. If you type ‘www.google.com’ in your browser, a DNS server (somewhere) is going to need to translate ‘www.google.com’ into an IP address so that a socket connection can be established.

The reverse of that (reverse DNS) translates an IP address into a meaningful name. For instance, ‘echoreply.us’ translates to 216.146.142.235, yet a direct lookup for the reverse (PTR) entry for that same IP translates to ’s1.echoreply.us’ which is the name of the computer that hosts ‘echoreply.us’.
