Sometimes you wanted to get rid of your crappy ISP DNS servers for good.

I’m using wvdial to dial up, here’s what I do.

Steps:
[*] Disable usepeerdns. Edit “/etc/ppp/peers/wvdial” file. Commented the usepeerdns line. Here’s what is should look:
#usepeerdns

[*] Disable Auto DNS in wvdial. Edit “/etc/wvdial.conf” file. Set Auto DNS Off.
Auto DNS = Off

[*] Add your own DNS servers to “/etc/resolv.conf” file.
Eg.:
nameserver 8.8.8.8
nameserver 8.8.4.4
Those are Google Public DNS service, a very good ones, and best of all, its free!

More of free public resolving nameservers here.

[*] Edit “/etc/dhcp3/dhclient.conf”. Find:
prepend domain-name-servers 127.0.0.1;
Add your nameserver to the line, ie:
...
prepend domain-name-servers 8.8.8.8,8.8.4.4;
...

[*] Done!

Good luck!
