Question : Slow DNS resolution / log entries

I have a Fedora 10 box on the lan at work.  I am using the same DNS server as my windows box and the same DNS server as about 100 other people in the buildng.  None of which have a problem with DNS resolution.  


Anyway, we have lighting fast internet access and I have been noticing it taking quite a long time to pull up simple pages.  I did some investigation which led me to /var/adm/messages.  I see TONS of logs like this:

Dec  7 08:06:23 putorious kernel: Inbound IN=eth0 OUT= MAC=00:12:3f:be:1e:3e:00:09:11:3a:88:0a:08:00 SRC= DST=172.24.20.16 LEN=311 TOS=0x08 PREC=0x40 TTL=58 ID=39323 DF PROTO=UDP SPT=53 DPT=54173 LEN=291


The SRC is my DNS server, I dont understand what this is telling me?  Are incoming DNS packets being filtered/dropped for some reason?

Any help would be appreciated.

Answer : Slow DNS resolution / log entries

What is the timing when you ask your nameserver 'by hand'?
Try:

host -v google.com your.name.server

Then try to ask about google.com google's NS:
host -v google.com ns1.google.com

Last line of output should contain answer time.

Are there some big differences in timing?
