Give this page a look.  It has a bat script called resolve.bat that will resolve the IP, DNS name, and Netbios name.  I'm sure you can remove the other 2 parts that resolve DNS and Netbios if you don't need them.

Vb6 code to resolve IP from URL:
URL to IP ... http://vbnet.mvps.org/code/network/iplookup.htm

Note: In demo Rem line "Text1.Text = GetMachineName()" so you can enter URL in Text1.

Here is another script to do it in VB.
'****************************************************************

'  File:    getipname.vbs  (WSH for VBscript)

'  Author:           M. Gallant    09/30/2001

'

'  Based on script by M. Harris & T. Lavedas:

'  posted to: microsoft.public.scripting.vbscript  2000/07/21  
 

'  Reads IP addresses via:

'    ipconfig.exe  (NT4 and Win2000)

'    winipcfg.exe  (Win95)

'  For NT4, Win2000 resolves IP addresses to FQDN names via:

'     nslookup.exe     (with default DNS server)
