Thanks for your help, guys. Didn't know dig existed for windows. Several ISPs (charter.net, alter.net) are choking on .us queries right now, but AT&T's name server is working ok for me. Here's one failing on .us, but .com works fine: C:\temp\dnstools>dig @24.197.96.16 com NS ; <<>> DiG 9.3.1 <<>> @24.197.96.16 com NS ; (1 server found) ;; global options: printcmd ;; Got answer: ;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 1940 ;; flags: qr rd ra; QUERY: 1, ANSWER: 13, AUTHORITY: 0, ADDITIONAL: 0 ;; QUESTION SECTION: ;com.

Thanks. Didn't have any *NIX boxes laying around to 'dig' any deeper.
i believe even windoze has dig at the command line, though i don't know in what directory it lies.
The web directory: http://www.isc.org/index.pl?/sw/bind/bind9.php or the ftp directory: ftp://ftp.isc.org/isc/bind/contrib/ntbind-9.3.1/BIND9.3.1.zip What is also very useful are the following two websites, so people can click around a bit and get nice pictures making everything crystalclear for them: DNSDoctor (which even supports IPv6 :) http://demo.dnsdoctor.org/ And of course DNS report: http://www.dnsreport.com/ Greets, Jeroen

It is perfectly possible. Unfortunately, all three nameservers of ".us" are behind the same AS and, unfortunately, they are all in the same /16. Checking the filters is a first step. PS: tracert exists on MS-Windows and c.gtld.biz replies to it.

the alter.net cache's you are using arent' guaranteed to work... especially for non-customers :) but... in general they do work, sometimes slowly as all manner of people use them regardless of their 'customer' status to alternet :(

I'm not seeing these problems though (though that problem might have been transient too) ; <<>> DiG 8.4 <<>> us ns @cache02.ns.uu.net ; (1 server found) ;; res options: init recurs defnam dnsrch no-nibble2 ;; got answer: ;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 9205 ;; flags: qr rd ra; QUERY: 1, ANSWER: 3, AUTHORITY: 0, ADDITIONAL: 3 ;; QUERY SECTION: ;; us, type = NS, class = IN ;; ANSWER SECTION: us. 6D IN NS c.gtld.biz. us. 6D IN NS a.gtld.biz. us. 6D IN NS b.gtld.biz. ;; ADDITIONAL SECTION: a.gtld.biz. 5d20h12m3s IN A 209.173.53.162 b.gtld.biz. 5d20h12m3s IN A 209.173.57.162 c.gtld.biz. 5d20h12m3s IN A 209.173.60.65 ;; Total query time: 144 msec
