Are you connecting through a router with a web interface? If so you can 
connect to the router and read the allocated IP address directly from 
it. Here is the script that works for my Netgear RP114 router, with 
tRouter being the address for the router, tName being the login name 
and tPass being my password. You would have to experiment to see the 
page address and exact text format.

   put "http://" & tName & ":" & tPass & "@" & tRouter & 
"/mtenSysStatus.html" into theURL
   put URL theURL into theData
   get lineOffset("IP Address :", theData)
   put line it to it+1 of theData into theData
   put word 1 of line 2 of theData into ipAddr
