how to grep for an IP address

[Elizabeth H]

I wanted to grep the IP address from this following exception. What is the easiest way to do this?

"var=something. something.somth ing.Exception : The IP xx.xxx.x.xxx cannot be used"


I want to grep the IP address from this string and store it in a different variable. Do i just use the regular regex pattern to grep an IP address or is there an easy way

One simple way would be to use regex like:

my $var = "something.something.somthing.Exception : The IP xx.xxx.x.xxx cannot be used";
$var =~ /(\d+\.\d+\.\d+\.\d+)/ ;
print "IP Address is $1 \n";
