In Wireshark, it uses DNS or what ever you manually have written in
the "ethers" or "hosts" file. Whois only shows assignments from the
various Internet Registries.
You can of course infer names (say looking at the "Host:" header in
a HTTP request) but this isn't done.
Unfortunately their is no magic to do this.

HI, all:
I noticed that wireshark can show the host name(or website
url) for an ip address precisely. I need such a function which
can convert an IP address to the host name precisely. With linux
command "whois", the result is very coarse. Can anyone tell how
wireshark did the conversion and can I write some scripts or a
small program to do this? I mean the input is an IP address
while the output is a host name or URL, Thanks!
