Well, you did say: "Am I to believe that the browser is NOT using /etc/resolv.conf"
which to me reads that you were thinking that somehow the browser itself should be
using resolv.conf. I'm sorry if I misread what you wrote.
If it is empty, NOTHING gets resolved.
Not "entirely" true.
With named not running.....
[egreshko@f16-1 ~]$ cat /etc/resolv.conf
# Generated by NetworkManager
#search greshko.com
#nameserver 192.168.0.55
[egreshko@f16-1 ~]$ ping misty
PING misty (192.168.0.55) 56(84) bytes of data.
64 bytes from misty (192.168.0.55): icmp_req=1 ttl=64 time=1.99 ms
since /etc/nsswitch.conf contains
hosts: files dns
and /etc/hosts contains
192.168.0.55 misty
if you take the "files" out of the hosts line....then NOTHING gets resolved.
nsswitch comes out of the box with files listed first for hosts resolution.
I do not modify it.
I was using nscd thinking it is a lightweight caching resolver. But as
it turns out it is useless.
Time for fedora to bury it :)
Re: My router: it does very little if any caching - and has no
configuration for it at all.
I will try bind.
I've not used it....but have heard good things about dnsmasq which, according to yum
info, is A lightweight DHCP/caching DNS server.
I have used dnsmasq as well, and communicated with it's author
a couple of years ago.
But as I recall, it did not seem to help much, as I observed that
browsing to a website with just a couple of minutes lapse time,
FF showed on the status line it was looking up the domain.
Perhaps the cache expiry was set to a very short time?
