Thank you for taking the time to write to us, but this is not
a bug. Please double-check the documentation available at
http://www.php.net/manual/ and the instructions on how to report
a bug at http://bugs.php.net/how-to-report.php

(number) 127.1.1.1  = 127.0

sorry, typo.

(number) 127.1.1.1 = 127.1

(number) 127.1.1.1 = 127.1
Yes, this is ok.
$ip = '127.1.1.1';
echo $ip == intval($ip); 
Ti is false and it should be false because 127.1.1.1 is not equal with 127.1

Problem is if IP is 127.0.1.1

$ip = '127.0.1.1';
echo $ip == intval($ip); // true

This is  127.0.1.1 == 127.0 and it is true. How it can be true? It should be 
false like in first case.

(number)127.0.1.1 = (number) 127.0 = (int) 127
(number)127.1.1.1 = (number) 127.1 = (float) 127.1
