[netCDF #VDL-808876]: NetCDF and IPv6

Hi Sean,

> Does NetCDF support IPv6?

The netCDF library doesn't depend on IPV6 unless you build it with OPeNDAP 
client support, which is the default if the curl library is installed where
it can be found by the configure script at build time.

If the curl library supports IPv6, then netCDF's OPeNDAP clinet library also 
supports it.

Recent versions of curl support IPv6 by default, but this can be turned off
at build time.

So, in summary, to find out if your netCDF installation supports IPv6, just 
check whether the underlying curl library it was built with has IPv6
support, using the "curl-config" command, as in:

  $ curl-config --features
  SSL
  IPv6
  libz
  IDN

and if "IPV6" is one of the lines in the output, it is supported.  If there is
no installed curl-config command, chances are the curl library is too old to
support IPv6.
