anyone running djbdns?

[Robert La Ferla]

I have an odd problem with djbdns.  A couple of common hosts (and I 
suspect others) don't resolve but nearly everything else works fine and 
has for years.  This problem has existed for years but I never took the 
time to fix it.  I want to fix it!

e.g.

These don't work:

# host www.edmunds.com
;; connection timed out; no servers could be reached
# host www.infiniti.com
;; connection timed out; no servers could be reached

Yet most work:

# host news.bbc.co.uk
news.bbc.co.uk. is an alias for newswww.bbc.net.uk.
newswww.bbc.net.uk. has address 212.58.240.143

# host www.boston.com
www.boston.com. has address 66.151.183.21
www.boston.com. has address 66.151.183.31

Here are the ROOT servers:

# cat ...dnscache/root/servers/@
198.41.0.4
192.228.79.201
192.33.4.12
128.8.10.90
192.203.230.10
192.5.5.241
192.112.36.4
128.63.2.53
192.36.148.17
192.58.128.30
193.0.14.129
198.32.64.12
202.12.27.33

What could be the problem?  How do I go about diagnosing this?

Thanks!
