hi Experts
just wondering if you can help me check a number between a specific range
if i have an ip address , how can i say the valid number for ip between 1 to 254
something like this
if ($ip ) =~ /[1-254].[1-254].[1-254].[1-254]/
{
}
what the pattern i need to type
thanks
You can try this:
$ip=~/(\d+)\.(\d+)\.(\d+)\.(\d+)/;
if ($1>=0 && $1<=255 && $2>=0 && $2<=255 && $3>=0 && $3<=255 && $4>=0 && $4<=255)
{
}

just wondering if i can do it in the patten matching
It can be done, but it is not pretty
$ip=~/\b((2[0-5][0-5]\.)|(1?[0-9]?[0-9]\.)){3}((2[0-5][0-5])|(1?[0-9]?[0-9]))\b/
