Did you read the man page explanation for 'time_namelookup' ?

   The time, in seconds, it took from the start until the name resolving was
   completed.

It simply cannot be zero to follow this.

Using the IP-only address disables the name lookup. You could easily verify
this by snooping on the network when you invoke curl, and you shall see that
there is no DNS traffic happening.

This topic reminded me of a document I write this summer that I've forgotten
about, which explains the timings libcurl reports (which are pretty
straight-forward translated to single -w variables):
