Re^3: IP Filtering RegEx needed

You're are absolutely right!

OTOH in which log would you find addresses containing an octet with '995'

My attempt was just a quick hack to serve the OP and is not fully tested, though I believe it's good enough to don't match other ranges, but I could be incorrect, and maybe I should have stated so :-(

Thank you!

My above code is absolute nonsense and was just a quick hack This should do it now on the specified ranges: `my $regex = qr/ ( 123\.145\.14[6-9]\.2 # match first specified range \| # or # second specified range: 135\.168\. # <= first 2 octets (?: # 3rd octet: 1 (?: 0[0-9]\|1[0-5] ) # 100 - 109 or 110 - 115 \| # or [1-9][0-9] # 10 - 99 ) \. # 4th octet: (?: (?:1[01][0-9]\|12[0-5]) # 100 - 119 or 120 - 125 \| # or [0-9][0-9]? # 0 - 99 ) $ # end of string ) /ox;` [download] I'm all puzzled now!

my $regex = qr/
(

123\.145\.14[6-9]\.2       # match first specified range

|                          # or

                           # second specified range:
135\.168\.                 # <= first 2 octets
(?:                        # 3rd octet:
1 (?: 0[0-9]|1[0-5] )      # 100 - 109 or 110 - 115
|                          # or
[1-9][0-9]                 # 10 - 99
)
\.                         # 4th octet:
(?:
(?:1[01][0-9]|12[0-5])     # 100 - 119 or 120 - 125
|                          # or
[0-9][0-9]?                # 0 - 99
)
$                          # end of string
)
/ox;
