What's wrong with these Regular Expressions?

I'm a newbie to Regular Expressions, and I'm wondering why the following regular expression line does not yield the required results.

preg_match_all("/[\d]{1}[\d]{1}\d?[.][\d]{1}[\d]{1}\d?[.][\d]{1}[\d]{1}\d?[.][\d]{1}[\d]{1}\d?\s\-/", $Article, $matches);

I'm trying to isolate the IP addresses in my access log files for my domain. The above regular expression will provide me a list something like the following. As you see, the IP's are obviously incorrect, at least until you get to the first period in the address:

070.108.214.195 -
170.108.214.195 -
270.108.214.195 -
370.108.214.195 -
4216.154.18.235 -
570.108.214.195 -
670.108.214.195 -
7216.154.18.235 -
865.55.105.19 -
965.55.105.19 -
10216.154.18.235 -
11202.156.14.79 -

Again, my question is how to tweak (or if necessary, completely rework) the above regex code so that the IP address will be found correctly.

Thanks,

PS My ultimate hope is to isolate the information provided for each IP and to save it to a stats database.

 

"/^((0|1)?\d{1,2}|2([0-4]\d|5[0-5]))(\.((1|0)?\d{1,2}|2([0-4]\d|5[0-5]))){3}$/"
Example

$ips = <<< ips
070.108.214.195 
170.108.214.195 
270.108.214.195 
370.108.214.195 
4216.154.18.235 
570.108.214.195 
670.108.214.195 
7216.154.18.235 
865.55.105.19 
965.55.105.19 
10216.154.18.235 
11202.156.14.79 
ips;

foreach ( explode("\n", str_replace("\r", '', $ips)) as $line )
    if ( preg_match("/^((0|1)?\d{1,2}|2([0-4]\d|5[0-5]))(\.((1|0)?\d{1,2}|2([0-4]\d|5[0-5]))){3}$/", trim($line)) )
        echo 'Success - ' . $line . "\n";
    else
        echo 'Fail - ' . $line . "\n";

PHP:

Returns:

Success - 070.108.214.195 
Success - 170.108.214.195 
Fail - 270.108.214.195 
Fail - 370.108.214.195 
Fail - 4216.154.18.235 
Fail - 570.108.214.195 
Fail - 670.108.214.195 
Fail - 7216.154.18.235 
Fail - 865.55.105.19 
Fail - 965.55.105.19 
Fail - 10216.154.18.235 
Fail - 11202.156.14.79 

Code (markup):

Only matches exact Ips.
