If your host name is not resolving properly from the NCDC website,
please make sure that you or your DNS administrator check for the
following. In most cases, fixing one or both of the items below
resolves any issues when trying to access free online data.
example:
123.45.67.90 has host name of jdoe.ncdc.noaa.gov and jdoe.ncdc.noaa.gov
points back to 123.45.67.90 Show this to your system/dns administrator,
who should then be able to correct the problem on your end.
nslookup, host, and dig are commands that can be used to test name
resolving but your name may resolve correctly inside your own network
but not outside it.
