Problems with naming resolution

[John Tan]

Ok. Some of the hosts that I have trouble resolving include :

www6.internet.gov.sg.
maillist.internet.gov.sg.
www.env.gov.sg.

Some of them can be resolved but cannot be resolved at other sites.
(see below) At other times I can resolve it. IS this normal or a symptom of 
some problem ? Appreciate if anyone
could help.

thanks
