read IP address

[kirk]

I have simply point to point network. Assumed that is possible to know
MAC address of remote machine. It's possible to get also IP static
address ?

kirk,
you might want to elaborate more about the application and how they're
connecting. Im alittle confused about what you're asking.

Ok you need to get the IP addres of a remove computer using .net..
Humm probably not the right way to do it but here is how I would do it
(not tested but it should work). Call Arp from the commandline and
pipe the results to a text file. Then read the text file line by line
looking for the Mac address. If the IP is on the same line as the Make
address then return the IP

function getIpFromMacaddress
Dim TempFile = "C:\somefile.txt")
Dim macAddress = "0-aa-00-62-c6-09"
if io.file.exists(tempfile) then io.file.delete(tempfile)
Dim shell = createobject("wscipt.shell")
shell.run(string.format("cmd /c arp -a >> " & tempfile)
Dim sr as new io.streamreader(Tempfile)
dim s as string = sr.readtoend
sr.close
Dim lines as string = split(s, vbnewline)
for i as integer=0 to line.length-1
if line(i).indexof(macAddress) <> -1 then
return split(line, vbtab)(0).trim
end if
next
return "Ip not found"
end function

Thanks you Sammy, Sorry English is not my native language. I try to
explain better. I have a embedded machine ( like PC104 ) with ethernet
connection. I open socket connection throught TCP/IP and I can send
and receive message all is ok. But with TCP I need to know IP address
before. In my application this information will be easly losed. Is
there anybody that tryed to know remote IP address. Consider that I
have always simply connection one embedded machine linked with one PC.
Thanks a lot for any suggest...
