<?php
include("conn.php");
$ip=$_SERVER['REMOTE_ADDR'];
$result=mysql_query("select * form ip where iip=$ip",$conn )or die(mysql_error());
if($result){
echo "<script> alert('失败');window.location.href='index.html'</script>";

}else{
mysql_query("insert into ip(id,ip) values(null,'$ip')",$conn)or die(mysql_error());
}
 ?>

$result=mysql_query("select * form ip where iip='$ip'",$conn )or die(mysql_error());

楼主确定是iip不是ip?
$result=mysql_query("select * form ip where ip='".$ip."'",$conn )or die(mysql_error());
------解决方案--------------------
$result=mysql_query("select * from ip where iip='$ip'",$conn )or die(mysql_error()); //from写错了
