Advice pls on what is happening on my system

BACKGROUND

I am on a cable connection in the UK with no other PCs or printers
attached. I use FILSECLAB's personal firewall.

I downloaded and installed "TreeWalk DNS" a week ago on my XP Pro
system. As I am in the UK I also installed the "ORSC Slave-Root"
package. I have to say I am not particularly familiar with the
technical details of DNS lookups.

OBSERVATIONS

Today I booted up. Before I manually launched anything I saw the
following entries shown below in my firewall monitor.

These entries have worried me because for the last week my PC has
been hesitating for several seconds before connecting to servers such
as (http://www.google.com or an NNTP news servrer) for the first
time. Subsequent connections seems as fast as usual.

Spybot (latest version with latest updates) reports nothing.

QUESTIONS FOR ANYONE

1: Which entries below are expected and which are unusual?

2: Have I got some subtle malware on my system?

3: How can I track back from these entries to find what programs
invoked NAMED.EXE to make these network connections?

4: Should I remove Treewalk or does it make no difference?

For the time being I have put these into my hosts file in order to
restrain them from connecting.

Thank you for any help.

NOTES:

(1) There were often several entries for each IP address but I have
listed only one.
(2) My IP address with port 1025 was always shown for each of these
entries
(3) The program associated with each entry was always Treewalk's
NAMED.EXE.
(4) In most cases, 70 bytes were sent and none received but for
192.5.6.30 (for which the IP lookup keeps failing) there was as much
as 10 KB of traffic in each direction!
(5) Sadly I can't find out anything for 194.54.112.30/FLUETANO.
