If you are looking for specific ip (no wild card) checking, you can use:

var_dump(is_private_ip('82.237.3.3'));

i want to allow users to filter their login based on their ip address (a new settings in the user preferences i will implement).

so if a user with a specific ip login and there is not restriction, the login is successful.

in any other case i was thinking this

if the user choose his full IP like 67.31.85.47 and he has this IP then the login is good
if a user choose 67.31.85.* and has this IP then the login is good
if a user choose 67.31.. and has this IP then the login is good
if a user choose 67...* and has this IP then the login is good
any other case it's invalid

the user can choose up to 5 IP restrictions. eg:

<pre><code>67.31.*.*
167.77.47.*
62.11.28.28
25.57.*.*
169.*.*.*
</code></pre>

i was tinking to strip the IP using explode and then compared to all restrictions he setup. 
this can be slow since i have to check 5 times * 4 (4 = IP exploded on the dot)

is there a faster way to do it?
thanks

PHP IP Filtering

我希望允许用户根据他们的ip地址过滤他们的登录(这是我将实现的用户首选项中的新设置)。因此，如果用户使用特定的ip登录并且没有限制，则登录是成功的。在任何其他情况下，我都是这样想的如果用户选择他的完整IP，如67.31.85.47，并且他拥有此IP，则登录是好的。如果用户选择67.31.85。*并且具有此IP，则如果用...
