Please help me!
I still use this code to send the IP value every time it changes. But that link has been Die.

"Http = require ('socket.http')
Http.TIMEOUT = 5
Local ip = http.request ('http://plotnikovv.ru/lm/logic.machine.92453i46.php')
Local oldip = storage.get ('myip')
If (ip ~ = nil and ip ~ = oldip) then
  Log ("Change my ip =" ip)
  Storage.set ('myip', ip)
  Mail ('aggfftc@gmail.com ',' Ctrinh Mr.Phuonghs569VC ',' IP '.. ip)
End
"
Link Die:
Local ip = http.request ('http://plotnikovv.ru/lm/logic.machine.92453i46.php')
