Isn't a DNS cache included in the browser or operating system already?
Check nscd. It's used in openSUSE for name server caching. man nscd for details. Firefox also has a DNS cache. So, using a caching DNS server won't provide much improvement for a single computer.
slightly OT:
I just used wireshark to watch chrome page refresh with Windows 7. I happened to have susestudio open on a page with no advertising and few graphics. the result was 4 outbound DNS queries for susestudio.com to my DNS server in 3 seconds. So chrome v31 does not cache DNS even during a single page refresh.
An application really should not be caching, it should leave that to nscd or a caching dns. -- Per Jessen, Zürich (7.1°C) http://www.hostsuisse.com/ - dedicated server rental in Switzerland. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
