Code:
alias localip {
  .comopen a wbemScripting.swbemLocator | .comclose a $com(a,connectserver,3,bstr,.,bstr,root\cimv2,dispatch* b)
  .comclose b $com(b,execquery,3,bstr,SELECT * FROM Win32_NetworkAdapterConfiguration WHERE IPEnabled = True ,dispatch* c)
  var %b $comval(c,0),%r
  while (%b) {
    if ($comval(c,%b,DHCPEnabled)) %r = %r $comval(c,%b,DHCPServer)
    else %r = %r $comval(c,%b,IPAddress)
    dec %b
  }
  .comclose c
  return %r
}
You can try this, I might write something for the external ip later

Not a bad suggestion but it can be done without using 'php byte code'
