Sorry I misunderstood. But I would be surprised you could write a generic enough function that would fit many websites. Most wedsites do not publish their IP addresss.
My suggestion would be to download the webpage, parse it, and retrieve the required information, rather thatn trying to navigate the page, through the internet explorer.
Soemthing like:

oIE = createobject('internetexplorer.application')
oIE.Navigate('www.tek-tips.com')
lcStr=oIe.Document.body.innertext
?lcStr

>>You could automate this site using GET and POST
