Where are my parts?

OK, who can explain this? I used to redirect parts.mbz.org to buymbparts.org by pointing to its IP address (74.208.144.39). Three days ago I changed parts.mbz.org so that has an A record of 199.166.24.53 The nameservers for mbz.org are:

From any of those servers, if I query the server from my XP laptop on Bell's wifi at Starbucks I consistantly get the wrong address, even though I'm querying the authoritatove servers directly:

C:\>host parts.mbz.org ns.ndc.vrx.net
Using domain server:

C:\>host parts.mbz.org ns1.vrx.net
Using domain server:

C:\>host parts.mbz.org mejac.palo-alto.ca.us
Using domain server:

parts.mbz.org has address 74.208.144.39

Yes if I query those nameservers from anywhere other than my laptop on Bells wifi I get different numbers from the same servers apparantly:

Bell is caching DNS records, ignoring TTLs by intercepting DNS requests? Really?

Reboot XP laptop.


C:\>host parts.mbz.org
parts.mbz.org has address 199.166.24.53

Finally. correct. (Use web browser to look at parts.mbz.org - get the wrong page.)


C:\>host parts.mbz.org
parts.mbz.org has address 74.208.144.39

Wrong! Lovely!
