I have a variable $var(s:dst). It can store either a number or IP.

How do I check to determine whether it is a number of IP?

I tried the following and it did not work:
If ($var(s:dst) =~ “^\d+\.\d+\.\d+\.\d+$”){
It is a IP.
}else{
It is a Number
}

for this particular case, you better use functions from ipops module:

Using regular expressions with variables is correct as you tried, not sure the \d is taken on consideration, you may try \\d or what I usually use is [0-9] instead of \d.

Cheers,
Daniel
